My wife has a Mondaine with only a single hand to indicate hours and minutes -- no second-hand. Resolution is only 5-minute intervals. She obtained it in Germany 10 - 15 years ago and isn't sure how old it is. There is nothing on the caseback or face to identify the model.
I don't know much about Mondaines, and have not been able to find out any information about this particular watch. I'd appreciate any assistance anyone could offer.
The case is very light (density-wise) and has a brushed finish. I suppose it might be titanium, but doesn't seem hard enough for that -- maybe a nickel-alloy? The crystal has small scratches (that show up very well in the photo) and is flat. The battery has died, but I assume that it still runs. I have contacted a Mondaine service shop for info about replacing it.
I've attached a photo.
