From the inventor of the often-copied one-hand watch, another first, the Botta-Design DUO 24 dual timezone one-hand watch. The startlingly simple one-hand principle makes you wonder why we have the big hand-little hand set-up in the first place. It’s all in the clever scale that condenses 60 minutes into the space between each hour marker. You won’t be doing any split-second timing with this one, but you will be able to see the exact time, to within a couple of minutes, with briefest glance—most of the time, that is all you really want and need. One timezone has a normal 12-hour dial. The inner scale, for the second zone, covers 24 hours, divided into convenient a.m. and p.m. sectors. A quick examination of the pic and all will be clear. The movement is Swiss, the manufacture is German, with stainless steel case, sapphire glass, and leather or steel link strap, and there’s a special Black Edition. It’s also waterproof to 3 ATM. Starting at €348 (about $450).
