Metro Datum Gangreserve

A symphony of a city in white, mint, and red: Designed by the renowned Berlin designer Mark Braun, Metro Datum Gangreserve is young and sophisticated, straightforward and slim. The clear minute indexes, hands as fine as quill tips, and a slim case makes this watch flattering to the wrist, the arm, and the eyes. And despite all its metropolitan credentials, Metro Datum Gangreserve is still Glashütte through and through: Equipped with a power reserve indicator and date function, a very special heart is ticking away inside—the exquisite NOMOS caliber DUW 4401 with the in-house built NOMOS swing system.

The designer explains this timepiece’s appeal—and what makes each Metro model so special—in this short film.
