[Help with] Constellation 168.0057 Cal. 751

Amuel · Sep 5, 2026

Hi everyone I’m trying to buy my first vintage Omega and would like to not get burned.

I’m eyeing this Constellation, pictures below (bad quality but already requested better ones). Ref. ST 168.0057, Cal. 751 (says the seller).

Asking price is 750€ + fees so around 800€ total.
Thanks in advance for any feedback. Wish you all a great Saturday.

This reference is one of the later C case models and should have cal 1021 movement and a different dial configuration with Omega logo at bottom and different text font.
So something has been changed along the way it is not 165.0057 movement and dial, looks like 169.029
Hard pass on this one.

Hi All,
I'm new to this forum, been on Watchuseek for a while, but thought I might get more info here. I've been a watch fanatic for a few years now, having a 1996 Speedmaster Date, 1950 Longines...

The seller is an antique shop, my guess is that they don’t really know which caliber is in as it should be 1021, maybe it really has a 1021 but then the dial would not match as you pointed out.
