Your thoughts on this one

Hello

I recently saw this watch in a local jeweller and was wondering if anyone had any thoughts on it. I'm new to OMEGA watches, but I have to say that this particular watch stood out from the crowd in the shop window. Any general information about the watch would be gratefully received, as would any ideas as to a ballpark cost for such a piece. The information I have in addition to the picture is as follows:

The watch is hallmarked 18ct gold
The diameter is 34.5mm
Originally the watch had an 18ct gold bracelet which was badly damaged and so it is now on a new OMEGA leather strap.
The production number is 61000104 which I believe puts it around 2000
There are four numbers in the case 1250050 3250050 1270150 3270150

Many thanks in advance

I'll check the year of manufacture for you when I get home. That's one of the early coaxial calibers.

No. I haven't bought the watch yet it's still in the jeweller's window. From speaking to the jeweller I'm guessing that he hasn't got the original bracelet but I could find out if it makes a difference. I must admit, I would have preferred it on the original bracelet.
