I bought this watch on the bay a while ago. It was discribed as 'not running' so it was a bit of a gamble.
I liked the look of it, original black dialed watches from the '40s/'50s are pretty rare :)
It's a cal. 351 with a 14k Gold Filled case.
THIS IS MY FIRST FULL RESTORATION JOB!
The movement was VERY dirty..
All of the plates were covered in a hard thick layer of muck. The main plate was very rusty, the front was covered in a green furr of copper rust.
It took me many hours to get it cleaned up, one full night in lighter fluid, a couple hours in a salt+vinegar solution, half a pack(!) of toothpicks, several brushes and some copperpolish.. It's still not looking 'as new' but it was close to a lost cause. Got unlucky there.. ;)
The reason why it was this dirty was quite simple.. There is an engraving in the caseback, put there in 1954. It's engraved too deep so sweaty dirt got in thru a couple tiny holes..
The dial also looked pretty dirty and rusty.. Thought I would have to get it redone.
A lot a work resulted in this! (sorry for the bad pics)
The dial needed heavy cleaning, and I'm quite happy with the result. Altho the paint started to let go at the edges, most of its writing is still very crisp! Glad a redial wasn't neccesary :)
The movement was a mess, but I got it working after a big load of lighter fuel and more agressive cleaner stuff
The bottom balance inablock jewel was broken and the clip was rusted thru, so they were replaced.
almost there, spring on the autowinder click system (not sure what it's called) was broken and was replaced.:
finished and cased:
I should take some daylight pics! too dark for nice clear stuff now.
Runs and keeps time!
