Thanks, I thought the same about the moon phase disc on the steel piece. And I noticed the non-red 31 and the lack of a disc.
I also have another one that I've come across that is 38mm, but I'm waiting on more pictures. If you could give me preliminary thoughts on what you think I'd appreciate it! It looks fairly original to me. The fonts match up, the moon phase disc looks correct, the date compax looks correct with the properly aligned circle that encloses it and with the red 31, the steel lugs look original and look like they haven't been re-welded on. My only concern is the crown and possible the pushers (it almost looks like the bottom pusher is slightly farther out than the top pusher), but it could be the angle.
Please let me know what you think! Thanks.
