Looks similar to the Heritage 300 Seamaster one, but not sure if it's a vintage one from the pic.
Yes, does look like the bezel on my modern Seamaster 300 heritage but…
1. Lume dot looks a little big and out of proportion.
2. Ridges around edge don’t look as sharp.
Both of these could just be distortions from the quality of the photo, but combined with the missing lume markers at 5, 15, and 35, I suspect it is a bezel from a fake.
