My father-in-law passed away recently and while my wife was cleaning out his condo she came across this Wakmann alarm watch. It is 35 mm in diameter with an 18 mm lug width, domed crystal and pretty nice bracelet(which I'll be changing as I prefer straps). The alarm is in good working order but the watch seems to be running a bit slow. I will be having it serviced. I haven't opened it up so I don't know what the movement is. On the dial it states France. My father-in-law was an opera buff and used to have my wife tape (reel-to-reel) the radio broadcasts of the Met. She had to set the alarm so she knew when to change tape reels.
