Omega Constellation 168.017SP

CK90s · Sep 23, 2025

Hi,
I've recently brought this Constellation. I was wondering if the rotor is the correct one for the year and serial number and not a replacement. I love the watch, only one scratch on the caseback but everything else seems good. Can anyone help to identify if all the parts are 100% authentic. There's an Omega symbol on the crystal

Current thinking suggests the ‘O’ on the rotor means it is a replacement part.

However, the 29,4xx serial places the movt at or around the point where the rotor style changed to this more simple version.

I don't see any reason to think there is anything inauthentic about this watch, but as Peemacgee points out the 'O' likely points to a replacement rotor. All in all it's a lovely watch.
