The Definitive Modern Speedmaster - Six Years With The Calibre 321

Recently, one of our readers asked me for an update on my ownership of the Omega Speedmaster Calibre 321. He also wanted to know how often I wear it compared with the stainless-steel Omega Speedmaster Professional Moonwatch introduced the following year (2021).

A most puzzling design oversight, compounded by stories of owners having to get holes drilled in the clasp to remediate this. At this price point? Seriously?

The FOIS2 has this. Why skimp with the Halo product? I guess they wanted to keep the clasp super slim like the original.

I've had my Ed White since March 2022, it's still my go to Speedmaster (had 13 at one time, now down to eight). Super watch. If I put it crown down at night it keeps time within a second a day. I sized the bracelet when I got it and that's it, never have had a need to adjust the bracelet during the day, in summer or winter, it just fits me fine. And I'm in and out of a humid climate and air conditioning, no need to adjust it. Have absolutely no need, or desire, for a bulkier adjustable clasp with 1/2 link adjustment. It's still the best Speedmaster in the current catalogue, or made since the original 321 was cancelled in the late sixties, imo.
