Why would anyone "pull the stem out and stop the wristwatch at night or when not wearing it" in the context of mechanical watches?
I read this the other day while discussing mechanical pocket and wrist watches:
Plus it is common practice to pull the stem out and stop the wristwatch at night or when not wearing it. You then have to set everything each time you put it on. That's…

Do really "all mechanical watches need to be maintained properly"?
Somebody answered this on a different question:
All mechanical watches need to be maintained properly. Every year or two they should be taken to a watchmaker for a service. This will include lubricating the watch, checking the bearings, for signs…

Watches: screw-down crown, gaskets, and what else?
I recently learned that some watches have a "screw-down crown", which to my understanding is made with a threaded crown stem that tightens into a threaded watch case. This seems inconvenient because a user has to loosen the crown, which can be hard…

How to regulate the RPM of a mainspring powered gear without an escapement?
I am building a watch and want to include a mechanism, where, upon the press of a button, the mainspring releases its energy causing the music box to play. Traditionally, the music box does not allow all energy to be released at once by using a wind…

How is energy in the hairspring restored in a mechanical watch?
I've read through the excellent guide to how mechanical watches work by Ciechanowski, but it leaves some questions unanswered.
The main spring of the watch, when it loses energy, can of course be re-wound using the watch's crown, and the guide above…

How can (many) mechanical watches keep track of the current day of the month when these vary so much over months and years?
Having dealt with dates and time in programming context for many years, I have realized what a nightmare our common calendars are, and how much they vary by the year/month/etc.

Are mechanical pocket watches inherently water-proof and last "forever"?
Recently, I bought a cheap (~$53) but elegant mechanical "retro pocket watch", newly made. That is, not an antique made in the 18th century or anything.
So far, it's worked flawlessly and feels very solid. But who knows what it will be like in 10…

How can a mechanical pocket watch wind itself from movement, and does it really get damaged if wound "too much"?
Today I received the mechanical pocket watch that I had recently ordered. It was this one: https://www.trendhim.se/guldfargat-mekaniskt-retro-fickur-p.html#full-gallery
I find it extremely fascinating to just stare at the mechanism. It's…

How can I make a needle to turn slowly CW to the final position, then return quickly CCW back to the initial position and to start again turning CW?
What I want is after the needle reaches 60 it should go back to 0 in the way showed in the image
The mechanism should preferably be based on gears which convert a steady continuous rotation to the shown slow CW turning and fast return.
here is a…
