I recently acquired two Omegas. They came with a few other Omega watches I intend to keep. When it comes to Universal Geneve and Longines, I can usually come up with an estimate of value - but Omega as a brand is so varied, I can't keep track. What would you expect these watches to go for? I am intending on selling them. The 343 Omega requires a service. The hammer is not properly positioned and so it doesn't swing without moderate force. The Omega 200 is just fine - though the crystal needs a buff.
The Seamaster is one of those funky late 60's / 70's watches that are pretty cool. I have no idea what those divers sell for, but they can be anywhere from mildly interesting to insanely coveted. The 343, if it's an original dial and not a service replacement, is going to catch the eye of a few of our vintage collectors that like bumpers.
I see asking prices for the Poppy 200 all over the place up to and over 3k Euros. However I am yet to see one sell for more than 2k, and that was a few years ago now and probably still trading on the Omegamania bubble. I wouldn't pay much more than for a Banana 200 in equal condition. So for a perfect example with original hands, dial and bracelet private sale 1.5-2k max. A little more seldom seen? Yes. A little more desirable? I'm not so sure.
There is one on the private watch sales that is for sale for 1650 pounds. It has been there for a while and might have been sold. I am in the love it camp and its on my list of watches to buy in the future. I would have bought it but another watch I wanted more was available so I bought that instead.
The poppy is very similar condition to the one I had (which is now sold) and went for £1650, which is a fair price in the current market, eBay would realise a similar return
I have a 343 chronometer- similiar to yours....The last one I saw sold on Ebay for about 800.00...I don't think the 343 RG has achieved the collector interest that 352 RG has...
