Case Serial No.:
1966 Diamond Excellency "J" on what might be the original JB Champion scissor center mesh band. It was on the watch when purchased years ago. Band has some weak scissor springs but oh well, it wears fine. M6 on both movement and case back. I have had this one apart in the past, but didn't have the ambition to remove the band to get to the case back. Manual wind 17J. Runs well, but displays some crystal crazing that I'll live with until I can locate and original crystal. I also have the DE "J" in yellow gold plate.
