Jean Marcel Tantum LE Manual-Wind Watch

Limited to a serialized run of just 100 pieces, the Jean Marcel Tantum is a captivating timepiece for a handful of reasons. The first? It’s remarkably slim—just 8 millimeters, to be exact—for a comfy feel on a bare wrist or under a cuff. The second reason? Its Swiss-made 17-jewel manual-wind movement can be admired from the back of the case through a sapphire display crystal. As if that wasn’t enough, this minimal watch tracks seconds via a 6 o’clock subdial, rather than a traditional seconds hand. Obviously, you’ll want to keep a beauty like this clean. As an extra treat, when you breathe on the case to clean it, you’ll see the Jean Marcel logo appear, only to disappear once the condensation dissipates.
