Although i am slightly annoyed by the “flight qualified in 1965” text. Its like justifying itself that it’s also a legit moonwatch

I’d go sapphire sandwich if ever. Applied logo, partly polished links on the bracelet, and supposedly thinner than the hesalite version. Ideally, I’d go hesalite but those pros offset the cons for me.
The 321 is undoubtedly a connoisseur’s piece but seems a bit flat when i look at most pictures. The new speedy with the bracelet and polished links look really nice. For once, i prefer the shine over the tool aesthetic!
