Firstly, it would have been nice for you to introduce yourself as a new member!
This site is predominantly for those with an interest in the replica world of timepieces, but that isn’t to say that we do not discuss genuine timepieces either (as replicas are based upon them)! We welcome without discrimination!
Do you have a model number for this omega model as it appears to be the 41mm omega reference 2541.80 according to your description date? If this is correct???? , the this uses the omega caliber 1538 which is based on the eta 255.461! I remember replacing one recently for a work colleague! It was the same model used in the Bond movie “Golden Eye”. They would sell online new for Approx 200 American dollars all depending on what part of the planet you reside! If you are savvy with basic watch repairs, you may do. It yourself and save heaps!!
Good luck and BTW Welcome to this wonderful fraternity of watch lovers!
