Reviving a bit of an old thread that I found during search - I've been looking at the Chinese set as well, but I have a question for the "hand-winders" on the thread - how do you deal with automatic mainsprings? When I do hand wind, it's from the outside in (the reverse of how the spring comes out of the barrel) and the split ends / extra pieces of automatic ends are especially tricky. I feel like there's no good hand-winding technique for these springs and winders are the only option.
A classic Seiko quartz rises from the junk pile today.
This was missing its crown and stem when it arrived, but otherwise it was in excellent condition, so I decided to trawl through my large pile of random stems to see if I had something suitable, and my luck was in.
I then couldn't decide whether it would look better with a silver or gold crown, but settled on the silver one.
Too much bling with the gold one I thought. Looking online, all of the similar Seiko watches with silver cases have silver crowns and gold cases, gold crowns, so I think I made the correct choice.
A little bit of a polish and a fresh leather strap, and it makes a very handsome addition to the 404 club.
If the mainspring unwinds back through the stem then the click may have failed. On these earlier longines the click spring is concealed under the barrel bridge.
Loose screw - most likely you loosened the bolt screw to far and it has fallen out. Remedy - remove dial to reveal bolt (aka setting lever and hold static while you reinsert the stew again).
