Nivada Grenchen F77 MK2 Open Heart
The Nivada Grenchen F77 MKII Open Heart introduces a fractured aperture at six o’clock, revealing the balance wheel while preserving the strong geometry of the original integrated design.
Each model uses a lightweight 38mm Grade 5 titanium case and bracelet, with a choice of Carbon, natural Green Aventurine or genuine Meteorite dials. Double-domed sapphire crystal, a screw-down crown and 100 metres of water resistance complete the collection.
