This is a Maurice Lacroix tumbler. A tumbler from Maurice Lacroix, a Swiss luxury watchmaker. It's an accessory for the tide watch. I'm selling it because I don't have a chance to use it. How about using it at work or in your car during your private time? As a Maurice Lacroix enthusiast, why not enjoy a cup of coffee elegantly with a Maurice Lacroix tumbler, which even professional watch connoisseurs recognize.
