I am looking for a Omega Marine Standard.
It is the second generation of the original Omega Marine, now powered by a T17 movement and with the crown protruding through the case as is normal rather than the crown inside like on the original Marine.
Usually has Omega reference number CK3635 or CK3637

I am also open to versions of the Marine standard with other brand names, as well as the Tissot Aquasport.
I am located in Austria and would prefer a seller within the EU but am open to offers from around the world.
