I have a huge pet peeve when it comes to the watch hobby/industry and its the word timepiece.
A watch is a watch, not a friggin' timepiece. If you insist on saying timepiece, then you need to know and accept you're an horological douchebag.
Remember, watches are first and foremost machines, tools, instruments, but they are not jewelry or art, therefore, they are not timepieces. Sure, watchmakers have taken their craft to levels that definitely rival great works of art, the same way a Ferrari does in the automotive industry. But just like a Ferrari is still a car not a travel-piece, a watch is still a watch.
Not a timepiece.
Watches, in other words, exist because at some point someone thought it would be a good idea (or it became necessary), to know what time it was without having to look for a clock tower. It wasn't as a way of self expression the way making music is, or painting something is.
In fact, telling the time isn't even considered a complication within the industry. This is because a watch can't be a watch without at least telling the time. It's its main purpose. Everything else is a bonus!
Even if we think back to the evolution of the Pocket watch, which was for practical reasons designed to fit in a man's vest pocket, to the various events that put watches on people's wrists, it was all because of practical reasons, not artistic reasons.
In World War 1 pilots started wearing watches on their wrists because it'd have been kinda hard to reach into their pockets while flying a plane in combat. They also needed these tools to be extra legible, hence the big arabic numbers in white on black dials.
When Rolex invented the first water resistant case and slapped it on the wrist of Mercedes Gleitze in 1927, which she wore while swimming across the English Channel, no one commented on how sparkly it looked in the water. People were wowed because water did not get inside destroying the movement. It was a practical invention that would revolutionize the world of diving, especially for the military.
When NASA approved the Speedmaster for space travel after a serious battery of tests, it wasn't so Astronauts could look extra cool in their space uniforms. It was a necessary tool, one that proved vital when the astronauts of Apollo 13 used their Speedmasters to time trajectory adjustments after an electrical short caused serious damage, which resulted in the need to turn off all nonessential systems. The timing of these adjustments needed to be exact. Not long enough and they would get the trajectory wrong, too long and they would use up the descent engine and be lost in space.
It's also important to understand why the word timepiece took hold, or what the true motivation behind it is, and that is this: yes, its because you're a douchebag, but also watch companies realized its a lot easier to sell people watches if they were appealing to their visual interests and not their intellectual ones.
If they had to sell you on the machine alone, they'd have to make an objective substantive case. If they had to sell you on the esthetics, well thats easier, because its subjective and we have the right to our own personal taste.
Not to mention, when you sell something to someone using their heart and not their brain, its a lot easier to overcharge.
So again, don't be a douche. You don't call your hammer a striking-piece, or a screwdriver a fastening-piece, so for the love of all things good in this world, don't call your watch a friggin' timepiece.
