On the outside, the Nomos Tangente Datum Watch looks deceivingly innocent, perhaps almost too simple to function. The watch’s 37.5mm face and slim profile lend it a delicate, elegant edge. However, as with all great things (people included), a minimalist exterior betrays the watch’s complex innards. The German brand has already won a 2012 Good Design for this model, which uses its signature “Beta” system to reduce weight by placing the date functions on the outside perimeter of the movement. A sapphire backing allows for full view of the watch’s inner workings. The Tangente Datum is available for $2,610 USD at Wempe New York and other retailers, as well as Nomos’ online store.
