Is Titanium Softer than Stainless Steel?

Answer: It depends on the Heat Treatment.

Titanium is not softer than stainless steel. In fact, titanium is generally harder than stainless steel. The hardness of a material is measured on the Mohs scale, and stainless steel typically has a hardness ranging from 4 to 5 on this scale. On the other hand, titanium has a hardness of about 6 on the Mohs scale, making it harder than most stainless steel alloys. On a third hand, heat-treated steel can reach a hardness of 7.

There are different types and grades of stainless steel and titanium, so the hardness may vary depending on the specific alloy. However, in general, untreated (non-hrat-treated) titanium is considered to be a harder material than untreated stainless steel.

Heat Treatment Matters

Unhardened titanium is generally softer than hardened stainless steel. When we talk about hardness, we refer to a material’s ability to resist indentation or scratching. Stainless steel is often hardened through processes such as heat treatment or cold working to increase its hardness. Hardened stainless steel can have a higher hardness level compared to unhardened titanium.

Unhardened titanium, in its pure form, is relatively soft compared to hardened stainless steel. However, it’s important to note that there are different grades and alloys of titanium and stainless steel, each with varying hardness levels. So, the specific comparison would depend on the particular grades of titanium and stainless steel being compared. Nonetheless, in general, hardened stainless steel is likely to be harder than unhardened titanium.

How a Watch Escapement Works

A watch escapement is a crucial mechanism in mechanical watches that regulates the release of energy from the mainspring and controls the movement of the watch’s hands. It consists of several components working together to ensure precise timekeeping. Here’s a simplified explanation of how a watch escapement works:

1. Mainspring: The mainspring is a coiled spring that stores potential energy when wound. As the mainspring unwinds, it releases this stored energy to power the watch.

2. Balance Wheel: The balance wheel is a wheel with a weighted rim that oscillates back and forth, creating a periodic motion. It acts as the timekeeping element of the watch, and its oscillations are what allow the watch to measure time.

3. Balance Spring: The balance spring, also known as the hairspring, is a fine coiled spring attached to the balance wheel. It provides the restoring force that keeps the balance wheel oscillating back and forth at a consistent rate.

4. Escape Wheel: The escape wheel is a toothed wheel that interacts with the pallet fork to control the energy flow. It rotates in small increments, known as “ticks,” driven by the unwinding mainspring.

5. Pallet Fork: The pallet fork is a lever that engages with the escape wheel teeth. It has two small prongs, called pallet jewels, which alternately lock and unlock the escape wheel teeth, controlling the movement of the escape wheel.

The interaction of the escape wheel and the pallet fork is the key to the escapement’s operation:

– Locking: As the balance wheel swings, the escape wheel rotates, and one of its teeth comes in contact with the pallet fork. This locks the escape wheel momentarily, stopping its rotation.

– Unlocking: The balance wheel continues its oscillation, causing the pallet fork to release the locked tooth of the escape wheel. The release of the tooth transfers a small amount of energy to the balance wheel, keeping it oscillating.

– Impulse: When the escape wheel tooth unlocks, the energy stored in the mainspring is transferred to the balance wheel, causing it to swing in the opposite direction. This transfer of energy is known as the “impulse,” and it maintains the oscillation of the balance wheel.

This process repeats with each swing of the balance wheel, creating a regular oscillation and precise timekeeping. The escapement effectively divides the unwinding of the mainspring into small, precise increments to ensure accurate timekeeping and control the speed of the watch’s movement.

It’s important to note that there are various types of escapements used in different watches, including the lever escapement, Swiss lever escapement, and co-axial escapement, among others. Each type has its own design and characteristics, but the fundamental principle of regulating energy flow remains similar across all escapements.

How Does an Automatic Watch Work?

An automatic watch, also known as a self-winding watch, is a mechanical watch that is wound automatically by the movement of the wearer’s wrist. It works using a combination of mechanical and gravitational forces to keep time.

Inside an automatic watch, there is a small weight called a rotor that is connected to the movement of the watch’s gears. As the wearer moves their wrist, the rotor rotates and winds a mainspring inside the watch. The winding of the mainspring provides the energy needed to power the watch’s movement and keep time.

The movement of the rotor is controlled by a series of gears, including a winding mechanism that prevents the mainspring from being overwound. When the mainspring is fully wound, the winding mechanism disengages, preventing any further winding of the watch.

To ensure that the watch keeps accurate time, automatic watches also include a regulating mechanism, such as a balance wheel and hairspring, which control the oscillation of the watch’s gears.

Overall, an automatic watch works by using the movement of the wearer’s wrist to wind a mainspring, which provides the energy needed to power the watch’s movement and keep time. The movement of the watch is controlled by a series of gears, including a regulating mechanism, which ensures that the watch keeps accurate time.

How Does a Quartz Watch Work?

A quartz watch is a type of electronic watch that uses a small battery-powered quartz crystal to keep time. Unlike a mechanical watch, which uses a complex system of gears and springs to regulate the movement of its hands, a quartz watch relies on the vibrations of a tiny piece of quartz crystal.

Inside a quartz watch, there is a small battery that provides power to a small electronic circuit board. This circuit board includes a quartz crystal, which is a thin piece of quartz that is cut into a precise shape and size. When an electric current is applied to the quartz crystal, it begins to vibrate at a very high frequency, usually 32,768 times per second.

These vibrations are incredibly regular and predictable, which makes them ideal for keeping time. The electronic circuit board measures the vibrations of the quartz crystal and uses them to regulate the movement of the watch’s hands.

The quartz crystal is also used to power a small motor that moves the hands of the watch. This motor is controlled by a tiny integrated circuit, which receives signals from the quartz crystal and uses them to adjust the movement of the motor.

Overall, a quartz watch works by using the vibrations of a small quartz crystal to keep time and regulate the movement of its hands. The battery-powered electronic circuit board inside the watch measures the frequency of these vibrations and uses them to control the movement of the watch’s motor.

How Does a Mechanical Watch Work?

A mechanical watch is a timepiece that uses a complex system of gears and springs to measure the passage of time.

At its heart is a mechanism called the Escapement, which is responsible for regulating the movement of the watch’s gears.

The escapement consists of a balance wheel, a pallet fork, and an escape wheel. The balance wheel is a weighted wheel that swings back and forth, while the pallet fork is a small lever that engages with the escape wheel.

The escape wheel has a set of teeth that the pallet fork catches and releases, causing the balance wheel to oscillate back and forth.

As the balance wheel swings back and forth, it drives the movement of the watch’s hands through a series of gears. The mainspring, which is wound by turning the watch’s crown, provides the energy to drive the gears and power the movement of the watch.

The rate at which the balance wheel swings back and forth is controlled by a hairspring, a tiny coil of metal that is attached to the balance wheel. The length and tension of the hairspring determine the watch’s accuracy and can be adjusted by a skilled watchmaker.

In summary, a mechanical watch works by using the energy stored in a wound mainspring to power a system of gears and a regulating mechanism known as the escapement, which keeps time by oscillating back and forth at a precise rate.

How Much Should I Spend on a Watch?

When someone finds out I am a Watchmaker, their first question tends to be, “How much should I spend on a watch?”

That is a good question, and a good question that applies to every purchase. “How much can you spend on a watch?” Is the response from a slick salesperson. “Not as much as I’d like!” is the usual response. This has solved the age-old question, “Do people wish they could spend an unlimited amount of money on a watch?” The answer is usually a resounding “Yes”.

But that doesn’t answer the question. So another typical response question is “What is your budget?” with the usual answer of “Not as much as I’d like!” Because to establish a budget, first you would have to list your requirements in a watch. You may not know your list of requirements, and it takes lots of education to reach that point. So we still can’t actually answer “How much should I spend on a watch?”

Simple Rule of Thumb

As a theoretical physicist, it comes naturally to me to think in terms of equations and math. This, as it turns out, is quite unusual, and less valuable than all my teachers told me.

As I have been contemplating the question of “How much should I spend on a watch?” for some time, I wanted to boil it down to some simple mathematical formula that would make sense to anyone.

Watch Industry?

It is difficult to make sense of an industry which in itself makes little sense, such as Watchmaking.

Watchmaking is a failed U.S. industry. Almost no jobs remain in the United States for Watchmaker. No watch factories exist. There are no U.S.-made major brands of watch available in any mass sales market.

The U.S watch industry died during the 1990s, as the last employed Watchmakers retired from service, and small jewlery stores with in-house Watchmakers permanently closed their doors.

The United States lost its pride in making things.

Watch Market?

Regardless of the US Watch Industry, U.S. citizens still wear watches. Maybe not every person, but still you see watches on people every day. They are still buying watches.

I checked a few of the major online sales channels, and the results are similar. The United States are buying extremely cheap, disposable watches at around the $30 price point. Unfortunately, it is a $3 watch.

Thousands of $30, crappy watches are being sold each month, at each online marketplace. These are never made in the United States. These are always “snap together” and never meant to be taken apart. If it dies, go buy a new one, ad throw this one in the landfill with all the others. Send another $30 permanently overseas and wear your crappy $30 watch another year, if you are lucky.

So how can I mathematically capture how much it costs to buy a crappy, mass produced, machine made of cheap materials, in a country with slave labor and no ecological responsibility, while still capturing how much it costs to buy a completely hand-made-from-scratch, Swiss museum piece?

And finally, today while walking the dogs, it came to me.

FAEstimate

You have to spend about $1 per week you wish to wear a watch.

FAE Watch Company

There it is, in all its perfect simplicity: $1 per week you want the watch to operate is all it takes to wear a watch.

It doesn’t matter the total number of weeks you wish to wear it for, this math still works.

It doesn’t matter how expensive, or how cheap a watch; simply multiply the number of weeks you wish to own, wear, and use your watch by $1 and that’s how much you will need to spend.

Want a watch for 5 years? 5 years times 52 weeks per year is $260. Pretty reasonable.

Want a watch for 40 years? 40 years, times 52 weeks per year, is $2600. Some of the $2600 will be paying a Watchmaker to maintain the watch over time, or the watch might just grind to a halt, like a car which has never had an oil change.

Cheap Watch Example

For that $30 bare-minimum in the cheap-watch market, you will get a daily-wear watch that will not quite last a year. Not if you really wear it each and every day, and no matter what you do. I would say 30 weeks, or about 7 months, is more likely a realistic lifespan for such a watch.

Can you make a $30 watch last longer by storing it in a safe with a nitrogen-only, temperature-controlled environment, with a master Watchmaker on-call to ensure it will live as long a life as possible? Of course. But notice how all the extra effort to keep the cheap watch alive still raises the cost above the original $30.

Can a watchmaker replace a battery, and try to clean it? Maybe, but it would cost more than a new one for $30. Chances are the cheap watch is already starting to decompose from remaining in daily contact with skin and its various salts, oils, fungi, and bacteria.

Will it last less than 30 weeks? Absolutely this is possible. With a plastic or if you are lucky glass crystal, the odds of it scratching are very, very high. How many scratches can you live with? If none, your 30 weeks to wear a cheap watch might get cut short.

If you like to lose things, and you like throwing things away, a cheap, $30 watch might be the best answer for you.

Let’s just hope the Asian factories will continue to create them so cheaply for you, because your refusal to purchase from the United States has made it that Asia is now your only hope. If Asian factories want a pay raise for its workers, or are expected to start following environmental impact laws, you can say Goodbye to your cheap, crappy watches and say Hello to expensive, crappy watches.

Expensive Watch Example

Let’s say someone overspends on a watch because they believe it’s got brand value over time. So they pay $16,000USD to buy a Swiss, automatic, mechanical dive watch, apparently designed for those who operate submarines.

The good news is that this watch is much more likely to be maintained carefully over its lifetime. It is more likely to make it into a Watchmaker for service. It is more likely to be carefully stored and well-treated. As a result, it is more likely to be functional and thus get “passed on” when its owner dies. This adds many years to the watch’s life, which could easily span many decades, if its various electroplated surfaces remain intact.

For this overpriced watch to achieve the rule of $1 per week, however, it would have to remain in service for approximately 300 years. That is because $16,000 pf $1 per week divided by 52 weeks per year gives about 307 years. It needs to be handed down about six times, or once every 50 years.

The Stainless Steel itself is at risk to not make it the 300 years. And it is more likely that the electroplated surfaces will decay first, followed by the dial, hands, and indices, as with most 100 year old watches.

But if you really want a watch that will last 300 years, it will take all of that $16000, and it will probably fall short since it is hard to test things over 100 years.

FAE Watch Example

I would put the FAE Quartz Field Watch against any other watch when considered with this new “$1 per week” FAEstimate. It’s extremely long service life, and high durability make it a watch that will function easily for the rest of your lifetime.

While the band, movement, dial, and hands may not last 200 years, the case definitely will. Stainless Steel should easily maintain service for 100 to 200 years.

Its crystal is not plastic, or even glass. It is a sapphire lens, which is scratch-resistant from almost all materials, except diamonds.

And while the shorter-lived materials cannot be avoided, they should still function for your lifetime, about 70-80 years.

For simplicity, we could even say it will last 50 years. This is a bit conservative, but realistic. But let’s not stop there.

Let’s just assume the FAE Quartz Feld Watch lasts only 25 years. You get it in college, and after about a dozen new bands, its still going strong after more than a couple decades of service. In fact, let’s just say 20 years of faithful service. That amount of time goes by in a blink.

Yet 20 years is more than a thousand weeks. For a FAE Quartz Field Watch, 20 years is just a warm-up.

Nevertheless, how much does a FAE Quartz Field Watch cost me per week when it lasts 20 years?

20 years times 52 weeks per year gives just over 1000 weeks; 1040 weeks. For a FAE Quartz Field Watch that is priced new at $249.95 that last 20 years: we divide $249.95 by 1040 weeks to give $0.24 per week. That’s a quarter per week to own a FAE Quartz Field Watch. Even with annual maintenance, the FAE Quartz Field Watch will still cost you less than $1 per week.

If it does last 50 years, which is very possible, we take 50 years, times 52 weeks per year, which gives 2600 weeks. $249.95 divided by 2600 weeks means it only costs ten cents per week! What about batteries? A 371 costs around $2, and you need one a little more than every three years. That’s around 16 batteries at $2 each, or $32 over the 50 years.

Cheap Watch for 50 Years

Just for fun, let’s assume someone changes their $30 cheap watch each 30 weeks during a 50 year watch-wearing lifespan.

50 years times 52 weeks per year is 2600 weeks. 2600 weeks is made of about 86, 30-week perods. That means, over 50 years, you would have to buy 86 cheap watches!

86 watches at $30 per watch is $2580 and a good 20 pounds of crappy watches piled in the landfill.
