Help with pie pan and 300hz Constellation’s

Peemacgee

There are no pie pans included in these photos.
Pie pans have a faceted dial with a distinct change in direction at the edge of the central plane.

Dials with a painted outer edge are not pie pans (no matter how the seller describes them)

A bit of advice if I may @Amuel

Mechanical watches and electronic watches are very different beast altogether (and come with their own distinct characteristics / issues)
If you are looking for your first Omega, try and focus on a particular style and reference of watch that interests you and hunt for that while reading as much about that reference as you can.

I have three f300 Omegas all with 1250 movements. They’re all great. They’re not universally popular, so you have a good chance of getting one in pristine condition if you look carefully.

There are two problems; first they require specialist watch repairers who are a diminishing number and who can charge a little more for servicing and repairs. Second, if you need replacement parts, it is generally these guys who have them. In London, I reckon to pay around £300+ for service/repair.

So far as the watches you posted, I reckon that the C case bracelet is incorrect for the watch.
