Hi guys, Quick question. Can someone tell me why some 930 end link holes on 2254.50 to access the pins are rectangular and go flat, and the 930 stamping is parallel? While some 930 bracelets are bigger, more tapered and have 930 stamping at 45 degree angle? Thinking of getting a 2254.50 and just curious as to the difference if its based on year etc. I noticed more of the 2254.50 from Japan have the first one, with the smaller rectangular openings. Any help would be appreciated. Thanks,
