145.0022 hand made inner caseback engraving?

Well strictly speaking it is both. The PIC was introduced at the end of the 1980s to identify the full retail package, the case number is and always was a descriptor of the function of the model, dial colour etc. That speedmaster is indeed a 3570.50.00 but still can be described by its case number. Try ordering parts by PIC alone and you will see how useful a case number is. The tritium 3570 is pretty rare, only made for less than a year AFAIK circa 1997.

thanks for this comment.

I will take back my comment that this is not a 145.0022 and fully agree with you.

I’m doing some more research out of curiosity with a coffee. Haven’t finished all yet...
But case back coding is correct then!!

Again a nice watch!! 🥰

It’s not that straightforward. The case number doesn’t actually tell you things like dial colour, hands, if it has a bracelet or strap...it’s the PIC number that does all that. In fact the same case can be used across a multitude of PIC numbers.

However, a within a single PIC there can be multiple case variations. If you look at the Bond diver, 25318000, there are 3 cases used, and changes for items like when a bezel pip on a diver went from tritium to luminova, or if the case tube changes from a friction fit to a threaded design are across those 3 cases.

Complicated indeed. Who would be a watchmaker!

Omega makes it pretty easy on the whole, but yes the system has quirks.

The only number that will tell you “everything “ about a specific watch is the serial number...
