Omega pocket watch from 1951 -- where to find one?

A friend of mine is looking for a pocket watch but it must be from 1951. They are getting married on what would've been her grandparents' 70th wedding anniversary so she wants something to commemorate that year. Any suggestions where she might find one or what makes / models might be a good start? I suspect most aren’t dateable, but perhaps an Omega or similar could be dated from the s/n or else one with an inscription or mil markings?

I'm assuming that the Omega movement s/n system is the same for pocket watches as for the wristwatches (but maybe not?). If so it's a 12.5m - 13m one she wants.

Chrono24 has two:

Or I suppose it's a matter of trawling through ebay looking at movements until a 125xxxxx - 13xxxxxx turns up.

Any thoughts or help appreciated. (I'm in the UK if anyone has one for sale.)

Thanks OF!

i think EBAY would be the best option in your case - you might be lucky
unfortunately i do not know that much about pocket watches so i will let someone else comment on any suggestion
happy hunt 😀
