Nivada Grenchen F77 Titanium Open Heart MK2 38mm, Green Aventurine dial, titanium bracelet, front view
F77 TITANIUM GREEN AVENTURINE OPEN HEART MK2 - 38MM
$2,295.00

An emerald-green Aventurine dial fractured around an open balance wheel, glowing through its cracks and powered by the Swiss SOPROD M100BV.


The F77 MK2 Open Heart Titanium Green Aventurine is the most luminous expression of the collection. The Aventurine dial shimmers with natural mineral inclusions, creating depth and texture. The fractured architecture radiates outward from the open balance at 6 o’clock, where the movement comes to life. When illuminated, Super-Luminova diffuses through the dial’s fractures, amplifying its dimensional effect and enhancing nighttime visibility. The 38mm Grade 5 titanium case combines brushed and polished surfaces, anchored by the signature octagonal bezel with eight exposed screws. Inside, the Swiss-made SOPROD M100BV automatic movement delivers a 42-hour power reserve and a visible balance wheel. Protected by a double-domed sapphire crystal and water resistant to 100 meters, this edition blends technical innovation with expressive materiality.
