    I’ve just encountered this same problem. There were initially concerns that the Omega Speedmaster Automatic Date circa 1991 was fake but my watch may come from a period of “cheap” 7750 17 Jewel movements?

    I have two case numbers which I’ve read enough on three pages to understand:
    1750043 & 3750043

    There is a serial number on the watch back:
    53638035

    I was going to pay for an Extract from the Archives because I love the watch but without a movement number I don’t see how I can do that.

    That is the serial number you would use, rather than the movement number. These movements were not numbered...at that time only the COSC versions were getting serial numbers on the movements.

    I have a newer 1957, and the serial number is on the lug like some have said previously. It is extremely hard to see for the untrained eye, it took me a couple of slow looks to find it. Mine is on the 6 o'clock lug on the 9 o'clock side.

    Archer you were right and thank you.
    Omega issued an Extract of the Archives for my watch. I couldn’t have provided more information with my request. I believe there are some anomalies in the Omega catalogue from a time when the company was struggling financially which led to using old stock parts including a stock of Valjoux 7750 movements.
