I just needed to point out the Nomos Tangente Ref. a hundred and one is water-proof to 30m, not 100m. It doesn’t detract in the least from it while. It’s a stunning timepiece! With minimum maintenance beyond battery alternative, they're ideal for people in search of precision and usefulness. Quartz https://www.watchesworld.com/germanys-top-10-favourite-luxury-watches/
