Need Help Identifying my SMP 300m

Hello! I purchased a used Omega SMP 300m blue wave dial. I am confused by the case having a serial of 49645538. it also has a model number of both 168.1502 and 368.1502, which i understand it is reflective of being a service case.

Would it be possible for this watch to be a complete fake or just an altered frankenwatch? Would a real SMP300m ever have a service case with serial 49645538? I am so confused what I bought. I don't know when those services cases were made. Do service cases have a different serial system?

Why do you think it is a service case? That looks perfectly straight for an early Bond middy.

Simply because i don't understand how the serial number is in the 49 millions or how it doesn't say 2551.80 inside the caseback

The serial is right for a ~1994 SMP. 2551.80 is the PIC. No Omega ever has the PIC inside the case, the other number is called the case number. Google Omega PIC for more info.

Why would a 1990s SMP300m bond middy have a serial in the 49millions

They just do. One theory is that they are left over late 1980s movements. I wonder if it’s in fact an 1109 or 1111 movement inside rather than the later 1120. Don’t be fooled by any online serial date lists you may have found. Virtually all are useless for most Onega watches after ~1980.

The movement is 1109. See attached pic

Every visit to OF I get to learn something new.

And Calibre Corner agrees:

The Omega caliber 1109 is an automatic movement found in some Omega Seamaster Pro 300M watches from the early 1990s (1993?). [...] This movement was later replaced by the Omega caliber 1120 in the mid to late 90s (1996?).

So you're confident in that i have a legitimate 1994 bond middy? correct movement, case serial and case number?

I am yes but we may be able to go one better if we politely ask @Archer to check it for you since he has Extranet access.
