Just posting this for bragging….


Bought this 321 on eBay for restoration. It’s been a battle of science and skill here… tiny alignments, chrono finger adjustments, beat error, missing hour hammer, and a stem/case geometry issue from a previous botched service. In fact, this watch is the most challenging job I’ve ever attempted. But proud to report that I’ve got it running to near perfection.

Vintage hands, period correct (likely original) DNN bezel (it’s a 67 transition, so Omega did this on occasion on the last 321s). Almost flawless (FLAWLESS) dial.

The patina tells a story, so I’m not polishing it any more than just a light cosmetic buff. But each pit and scratch looks like a well worn and well cared for piece of history.

Anyhow, enjoy some pics!


(Amplitude actually 270)

Excellent work !!!
and i wondered about your amplitude as 330 is very high but you already mention its 270 which is excellent. ( so the standard lift angle in your app is set to 52 ? )

Enjoy it well.

Yes the app initially defaults to a lift angle of 52. I set it to 40, but I don’t trust the apps always. So I visually confirm by recording the swing in slow motion. (Full swing divided by 2 = amplitude). 😀
