Nivada Grenchen F77 Open Heart Titanium Skeleton MKII

The F77 MK2 Open Heart Titanium Skeleton reveals the mechanical soul of the collection. Its vertically brushed black gradient dial appears shattered, opening a precise aperture at 6 o’clock where the balance wheel beats at 28,800 vibrations per hour. The fractured architecture creates depth while preserving legibility through applied titanium-toned indexes. Crafted entirely in Grade 5 titanium, the 38mm case features alternating brushed and polished surfaces. The iconic octagonal bezel with eight exposed screws reinforces the unmistakable F77 identity. Inside beats the Swiss-made SOPROD M100BV automatic movement, offering a 42-hour power reserve and marking a technical evolution within the F77 line. Protected by a double-domed sapphire crystal and water resistant to 100 meters, this edition balances sport-luxury heritage with contemporary mechanical expression.
