The case back is cleaned of debris (you don't want crap falling into the watch), the case back opened, the inner cover removed, loosen the setting lever screw maybe 1.5 turns (turn it too much and the dial side of the watch has to come apart), remove the stem and crown, then unscrew the crown from the stem. Honestly if you have to ask, you should really take it to a watchmaker. Cheers, Al
Agreed for the 321, just because it has such value. Like many tasks performed the first time, there's always the chance things don't happen as intended. It would be far less tragic for this to happen to a less valuable, less historically-significant timepiece!
Just to know...if it was something simple...guess for some it would be but not for me so off it goes. Cheers and thanks!
I've always been partial to visegrips. But then, I think a Timex Marlin is a fine high class timepiece, of unparalleled accuracy and quality, generally undervalued by the world at large.
remove the inner cover credit domingo chavez screw the setting lever, be careful if you do one round more, you'll have to remove all pieces of the caliber. (sorry for my english writting)
