Had this for a while, spent a lazy Saturday working on it
This is a 1958 284 (30 T4 SC PC AM 17 Jewel), shared with the Railmaster and Ranchero.
As you can see, the winding/setting mechanism was pretty messed up and rusty - the set lever had snapped/rusted through, the set lever screw was a seized mess plus lots of rust on the lever, set bridge etc. Some rust on the crown and ratchet wheels. Watch was not running.
The set lever was pretty hard to find, I ended up sourcing a second hand one - and a new set lever screw. I decided to salvage everything else, as the parts are simply getting hard and expensive to source, and it is probably better to save them for a better watch or one where a little surface pitting cannot be lived with
Objective is a well running, functional watch - maybe even a beater. Due to the dial, this one will never be a perfect resto.
In parts (most not all), after the first clean
Cleaned (lighter fluid, peg wood and elbow grease - and my favorite, electric toothbrush ) and ready for assembly
Derusted and oiled setting mechanism
Polishing the rust off the ratchet and crown wheels took a long time, and are not perfect.
Victory - running (no top jewel yet)
Cased, a good size @ 36mm.
Rough dial, but fine and wearable on the wrist. The case has nice bombe lugs.
I'm wearing it today
Crown is very worn and a new one is on the way. Although the replacement doesn't have the small Mercedes symbol inside the Omega symbol indicating an early Naiad. I'll fit a new stem at the same time.
So that was my first Omega repair/service. Quite a nice movement to work on, the plating held up well, and the parts fitted snugly. What I liked best was all the oversized screws - much easier to work with than the usual ones.Omega Museum says...
