The old 36,25 mm have a smaller or no lume plot at all at 3 o`clock to make room for the date.
Please correct me if I am wrong, I am on thin ice here, I only got the 41mm.
See that's what tricked me too into being unsure, cause I wasn't aware if or not there were any Seamasters with the date at the 6 o'clock going around and it's not a no date, it's the date at 6 version. So I am on thin ice as well.
