aprox 38mm...bezel has light scratching and is in great vintage condition dial and hands are funky and have a have nice patina to them. crystal has a noticeable scratch from the date going past the center and one going north south by the date. buff out or replace for a striking watch. watch keeps time and i do not know the service history. pretty sure this has a felsa movement but i can't verify. it has a roulette date wheel in red and black The Allaine Diver has a style that is wholly unique and absolutely eye catching. This watch was also made by Mirvaine and Ovidgal and a new modern spin by Zelos a few years ago. 399 + ship CONUS
