Speedmaster '57 clasp on 321 bracelet
Quote:
Based on my measurements on the 50th anniversary it is not compatible without modifications. ![]() Hope the Speedy 57 clasp fit on the 321 bracelet without the need of other parts or modifications ! ![]() Sent from my iPhone using Tapatalk Pro

I’m not gonna lie, it would be nice to have some on the fly adjustability on the 321.
Again, I’m not sure it trumps losing that beautiful vintage logo on the clasp though … ![]() |

The width of the clasp arm on the 50th anniversary is about 6 MM while on the Speedy 57 is about 7 MM. if the width of the arm in your 321 clasp is about 7 mm should be a direct swap. ![]() Sent from my iPhone using Tapatalk Pro

I'll take a caliper to it when I'm back at home. With the leatherman here at the pool it looks like 6.5 mm. Can you just file 0.5mm off each side of the little interface that sits inside the link and use the rest of the clasp as is?

Yes you could shave .5 MM on each side of the interconnecting link groove or at the arm. Don’t want to modify the 57 clasp, but rather modify the interconnecting link as long as can get an extra ordered (imagine is about $70) to have it just in case decide later to sell the bracelet back on its original conditions.

Got it. Just want to see what would be needed if it doesn't work for me. EW bar width is confirmed at 6.5 mm per mitutoyo.

My Mitutoyo is out of batteries ![]() Reading on a scale think it is 7 MM width so you probably need to shave .5 MM to make it fit ![]() ![]() Sent from my iPhone using Tapatalk Pro

Speedmaster '57 clasp on 321 bracelet
Quote:
Thanks for this pic. It's definitely 0.5 mm bigger than the EW bar. I think since it's only 250 micrometers from each side I'll tape some 3M 400 grit abrasive on the work bench and just swipe the top section 10 times on each side, measure, repeat until I hit 6.5 mm. It's so minor I don't think you'll be able to tell if the grain is all in one direction. There's also some slack in that joint that will help a lot. ![]()
