A friend has come across these hands from a watchmaker's deceased estate. The watchmaker, Omega trained, worked with Omega and other Swiss brands over the course of his career.

What would you say he has here?

Seamaster?


Left: Speedmaster Alpha straight groove? Right ??


Speedmaster A1 Broad Arrow (different size arrows?) or Seamaster?


Maybe?

You need to measure the hole sizes to get a better idea. As the broad arrow hours could be for a variety of models. Here's a good starting point, there are quite a few more threads.
