No and no.
The watch is only waterproof as long water deosn't get inside. Water can cause corrosion and leave up residue. Especially since it's unlikely the water that will get inside will be pure. It will contain minerals and might be slightly acidic. Besides, pocket watch is very delicate mechanism. When the water rushes inside, especially under pressure (...

I got my first wrist watch nearly 50 years ago. It was fully mechanical, spring powered, no batteries, & needed to be wound every day. My second watch, obtained a few years later, was also fully mechanical, but automatic - meaning it had a rotating weight/pendulum that moved every time the wrist moved and it wound the spring.
About 40 years ago I bought ...

Pretty sure they are not all stainless steel. I would expect some brass and I don't think I would expect the springs to be stainless steel.
Different metals with water result in galvanic corrosion. And stainless steel can still rust. Also, water leaves behind residues and junk. And water provides resistance to the gears and mechanical oscillators so it would ...

Dog leashes allow line to run, retract, then slide a button to lock the line in place. Dollar stores have inexpensive options.
This takes care of locking after full retraction: Include a ramp and stop with a bead (on the line), so during retraction once brought behind the stop-engagement this prevents the line from re-extending.
If you want a seat-belt ...

First of all, this is very much depended upon the implementation.
Having said that, the chances that damage occurs during self winding are minimal. It would take a pretty bad design to do that, and usually the people that still make watches are very experienced and with attention to detail.
So the only case that you might actually "hurt" the ...

I expect it works the same as a wrist watch type ; There is a weighted wheel , that is one side is substantially heavier than the other side . When the watch is moved , the heavy side of the wheel rotates so it is on the bottom. By using a ratchet , this rotation winds the main spring when rotation is in the correct direction . In the opposite direction the ...
