One for the experts
Has anyone come across a date at six 1950s Omega Seamaster with this movement I believed that
They were powered by either 353 or 355 movements
Or is this something of a rarity
Sorry no photo

 

Did you google “Omega 355” lots of examples.

 

Like this one?

 

Can't be too rare, I've got one.

 

501 is a no date movement, period.

 

I wondered about the title too, then I read the OP and see its about a bumper.

 

Thanks for the posts on this one as has been said the 501 is a non bumper movement
And I would expect to find it in an Omega Seamaster with rhe date at the three position
Or more likely a mid to late 50s no date seamaster

 

I think you misunderstand how the movement numbers work. See here for info on the 50X movement’s. The 501 has no date at all. The 502-504 have a date wheel.

And for the bumper with date 353

Here a ref. 2627, cal. 353 from 1952, is has nothing to do with a cal. 501
