Hello dear members,

To build up my Omega knowledge, I was looking at seamasters pictures around year 2000 and I notice one marked
"Seamaster Professional Chronometer".
To appreciate the differences between models, Does someone can tell me what is behind the words"professional" and "Chronometer"?
Thanks

 

Why don't you start at the Omega website, lots of info.

 

Thanks, but it is still not clear.

 

I think professional is just a naming. And chronometer is a certification given to watches that upheld the standard given by COSC
