Why It's Interesting
Compact 38.5mm and still rated to 200m, with proprietary crown sealing usually reserved for Sinn's dive pieces. Bead-blasted finish keeps it understated. At around €1,400 entry, it sits between Tudor Black Bay 36, Nomos Club, and Damasko DA variants, but leans more instrument than any of them.
