I got the Mondaine from Drop that came in the Red case; it looks just like this except for it's in a red block (I think black was the other option). After less than 6-months and the battery is dead. It looses time every month. There are supposed to be 3 magnets on the back, but there are only two. I wouldn't buy another.
rpaulsenI bought 2 of those as well. Same results. Dead batteries within months and missing magnets to hold the clock in its base (block). It falls out quite easily.
