Last night while I was rummaging about in the watch room I rediscovered this little gem that came in a box of watches I won at an auction. This was not what I was after so it’s been sitting a while. So this afternoon when I got home from work I thought it needed a little attention. A good cleaning inside and out along with a new strap and crystal we have this lovely Water-protected Olympic watch.
It has a movement I’m not familiar with , a Buren 481. I may be wrong but it seems that you can replace the mainspring without disassembling much of the movement.
The case also has the handy adjustable water resistant stem tube.
