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).
I am ordering some things, and thought I'd try again to get this guy back on the road. The Incabloc springs fell out, and I broke one trying to get it back in. I tried micing it, but what I'm getting doesn't line up with any of the springs I see on the Incabloc parts chart. I was hoping to back door it by seeing if I can figure out what setting the movement it's based on is supposed to have, but I can't figure out what the movement is. The only markings are a faint "+ -" on the balance cock, and a star on the rotor (pictured, but difficult to see) that was under a decorative plate.
