Came across this one recently and I can't say I've seen a dial like this. Anyone seen anything like this before?
Done some looking around and the movement is a Favre Leuba cal 251. Still no sign of this dial variation however.
Check this one out - I was told by the owner that it’s form late 50’s possibly early (60/61) by the original owner. Doesn’t wind at the moment, seems to be stick when rotating the crown. Original band too... exactly as he bought it many years ago.
