Buler divers watch. Clean case and great dial 41mm without crown makes this a big heavy watch with bakelite type bezel that turns. Runs well but have not timed over a day for gain/loss. Very clean overall sturdy watch. As with any vintage diver waterproof is not suggested. Appears to have a 25 jewel ETA movement. Also has a vintage and desirable Tropic Diver Band.
