Here we go again...another Constellation for consideration

At the risk out of wearing out my welcome but nonetheless grateful for everyone's assistance on avoiding a franken/fake the other day, I have come across another listing that seems legit but would appreciate some input advising of any red flags you might see. Many thanks in advance! The seller's description as follows;

Case: 35 mm stainless steel case showing honest signs of previous wear.
Dial/Hands: Original Omega silver dial, it has a few marks as expected from a vintage watch. Original hands and crown.
Movement: Omega caliber 501 automatic movement which has been recently serviced by a watchmaker and is running -1 seconds per day.
Crystal: Acrylic showing very light signs of marks.

Unfortunately not. These are the seller's photos. However. I've attempted to sharpen some of them

I suppose it would but I don't have any. I do however, have an opportinity to see the watch in person as he lives in Calgary.

I agree, the case does look polished and here's a caseback photo which also looks polished. I'm thinking I'll give this one a pass...

Seller is asking $1250 US
