Omega Seamaster 300

The reference is 165.024 with a sub reference -64. I might be wrong but I wouldn’t expect to see a big triangle dial on a -64 but again, don’t take that as gospel.
In the current market I’d say it’s worth maybe £3000 give or take.
Who quoted £2200? I’d advocate sending this to Swiss Time Services for a quote.

What did the watchmaker say the movement needed? $2200 would almost buy another 300

Here is some nice info regarding your reference!

Enjoy!

Whoever gave you that quote for repair is, I suspect, going to send it to an Omega repairer and then keep the balance as their broker fee. Serial will probably be in the 24mil range. The thing that interests me is that I didn't think the BT was a thing on a -64? I would like to see a clear photo of the 3, 6 & 9 and the movement.

Welcome @Vixter05 - as Wes said, the 165.024 is the model reference number. To answer your question directly- depending on variables like condition of every detail on the watch and originality- they can be worth anywhere from £6-12k- but the market can be very fickle. Your dial isn’t in the best of shape, hands have been relumed, case may have seen a polish/rebush at some point (can’t tell from the pics) and bracelet isn’t original- so yours probably resides towards the lower middle part of that range.

For service in the UK, contact Simon Freese

He has a great reputation specifically working with vintage Omega and is know for his quality and integrity. Service price will be no where near what you were quoted.

The dial looks original but the hands were relumed at some point (which was pretty common as the lume could dry out and fall out of the hands). If Simon doesn’t do reluming he could send the hands off to James Hyman to do them to match the dial.

If you value this as a family heirloom, then resale value isn’t of much concern- but you wouldn’t be throwing good money after bad.

If you just want to sell it, then don’t do anything to the watch, keep it as is and you will probably have received a few PM’s from this post offering to buy it already.
