Newbie question: age/ref. number/caliber list for Speedmasters of the last 30 years

101010oxo · Feb 2, 2020

I am looking for a list referencing year of manufacture/serial number/reference/caliber of Speedmaster Professionals appr. 1990-today.

All the lists I could find on the net only list these things up to the 90s or 2000 but nothing after. I often find watches for sale online were ref number/year/caliber seem to be contradicting, e.g. a ref. ST 145.0022 with a caliber 1861 made in 2005...

For example these lists contradict and don't cover the last 20-30 years:

Most lists stop at the 3570.50.00 a model that was around until 2014 before the big box and change to ref: 3674836377472637487627483620988

( me poking fun at the current long reference number Speedmaster )

Thank you. Is there a way to correlate a serial number with a year of production, eg. a 77xxx number?

Mind you my 7777xxxx was bought new in 2013

Great, thank you!

Now I only need the calibers 861/1861 and the reference numbers.

There were no Speedmaster professionals with serial numbers starting between 48 and 77.

I think your assessment is correct ;-)

So the above list is for all Omega watches? But Speedmasters went from 48xxx to 77xxx? In 2005?

Also I have gathered from the mentioned references that the 1861 superseeded the 861 in 1997?

And then I read:

New reference for the 145.022 (PIC number 3350 B on leather strap and 3351 B on steel bracelet from January 1988, then 3890.50 and 3590.50 since December 1989 then 3870.50 and 3570.50 since 1996) same engraving on caseback as the 145.022

So after 1996 no more ref. 145.0022. But what does "same engraving on caseback as the 145.022" mean? That the 3570.50 case backs were engraved with 145.022 or 145.0022?
