Anyone ever do this? I have some 6309 Sample watches I bought years ago. A few months ago I got a few 7546 watches on Yahoo Japan. One was not working and had an ugly case to boot. I serviced it this weekend and it seems to be happily ticking away. So I was thinking of combining resources and put the 7546 into a case I like.
The 7546 has a tab on the dial and the 6309 dials do not so I might have to swap dials. One candidate has a Seiko 5 dial. That could cause some head scratching down the road.
