Help and advice with 3 Omega Watches

I can tell you that the Constellation Chronometer has a solid gold dial. 🥰

All three look to be in great condition.
The papers/booklets should have model numbers etc that you can Google to find more info.

As to value, you can search places like Chrono24 to see what asking prices are.
Some of our US members may have a better idea of value as it can vary, depending upon where in the world you are.

Peter Blake GMT. Worth a few grand.

Dynamic III chrono worth a few grand.

Gold dial, fancy f300. Also worth a few grand in gold alone. The “OM” on the dial stands for On Massife which was required on solid gold dials for a period by Swiss law.

Over 10k in watches is my guess.

With stainless steel watches, production runs were in the hundreds of thousands, so there are a lot of examples around.
The solid gold Connie would not have been produced in large numbers, and a lot would have been scrapped for their considerable gold content, therefore there aren't many survivors, especially in that condition.

Please ensure that the battery is removed ASAP. A flat battery can degrade and leak electrolyte into the watch, which isn't good.

A Dynamic Chrono is around €2K, and the Seamaster GMT is around $2.5-3K. I sold a Dynamic last year and follow the GMT market pretty regularly. There isn't that much gold in the Constellation - a variant not particularly sought after, I'd put it at around $1.5K.

I am not downplaying the attractivenes of the watches, they are really, really nice and would make an excellent collection in their own right (which I guess they were...). A GMT diver, a flyer chrono and a vintage, gold dress watch. All are fantastic models - someone knew what he was doing buying these 😀

@mountainguy - you can look up the reference numbers in the papers to research some more, just remember that most prices you see online are asking prices, not sales prices (especially on Chrono24...). The Seamaster GMT is likely a ref 2534.50.00, the Dynamic is a ref. 5240.5000 and the Constellation probably a ref. 198.0022.
