To be honest, I only put it on for a moment since it’s both NOS and also today is Speedy Tuesday... (Wakmann Regate, with Lemania cal.1341 - the base/predecessor movement of the Omega cal. 1040/1041)
I am wearing this one today, it almost gets no wrist time but maybe once a decade ( literally) it gets to see the sunlight. It was my Fathers watch and he almost never wore it and when he passed away in 1980 it went to me where other than a full service back in 1990 it never got worn. Since that time its been worn maybe 4 or 5 days total, main reason being I hate leather straps and putting on and doing up buckles is a chore to me and the previous expander bracelet wasnt (like all) secure as it would have likely flown off my wrist. Essentially its a new watch, though I changed out the metal expander bracelet that had graced ( disgraced it) it for the last 40 plus years at the beginning of last year with an Omega leather one but unfortunately until I can get a period Omega rice grain or similar metal strap its unlikely to see much sunlight except for days like today where I will wear it in remembrance of my Father.
