I'm shopping a gen crystal for my 116610ln (B25-295-C12-C1) and I see crystals advertised as gen in 2 different blister packs: https://www.ebay.com/itm/ROLEX-GENU...483816?hash=item23d41c5c68:g:kFMAAOSw69Begm-k and https://www.rolexforums.com/showthread.php?t=728608. Can those both be gen crystals but in different blister packs? Thanks in advance!
