F77 Titanium Skeleton Open Heart MK2 Watch - 38mm 68023A77

The Watch

The Nivada Grenchen F77 Titanium Skeleton Open Heart MK2 brings a modern, innovative approach to Swiss watchmaking. This watch features an octagonal Grade 5 titanium case, a material known for its exceptional lightness and strength. Matte finishes combining brushed and satin surfaces give it a sophisticated yet understated look. At 38 mm in diameter and 12.20 mm thick, the watch is proportioned to fit a range of wrists while maintaining a subtle presence. The screw-down crown, positioned at three o'clock, is easy to use and supports 10 ATM water resistance for activities around water. A fixed bezel completes the balanced case design while helping protect the dial and movement.

The Dial

The Nivada Grenchen F77 Skeleton Open Heart dial stands out with its brushed finish and skeleton design, offering an intriguing view of the movement inside. More than a way to tell time, its open-heart design makes the mechanics part of the experience. Elegantly shaped hands coated with SuperLuminova are easy to read in low light, alongside well-positioned hour markers and a minute track. An anti-reflective sapphire crystal provides a clear view of the dial and excellent scratch resistance. Distinctive and expressive, the dial celebrates watchmaking craftsmanship, bringing style and function together in black and gray.

The Movement

Inside the Nivada Grenchen F77 beats a Swiss automatic movement, the SOPROD M100BV caliber. Known for its reliability, it runs at 28,800 vibrations per hour (4 Hz) for precise timekeeping. Its 42-hour power reserve keeps the watch running for more than a day and a half off the wrist. This performance reflects Swiss watchmaking expertise, with each component carefully assembled for reliable operation. A transparent caseback with sapphire crystal lets you watch the oscillating weight in motion, adding another visual dimension while protecting the movement.

The Bracelet

The Nivada Grenchen F77 offers a choice of two bracelets to suit different styles and needs. The first, made of titanium, has a brushed finish that complements the case for a clean, contemporary look. Titanium is also hypoallergenic and highly durable, supporting comfort and long-term wear. Alternatively, the adjustable Velcro strap offers a flexible, comfortable fit for active everyday use. Each option features a folding clasp for a secure fit and easy wear. Choose the bracelet that suits you from the drop-down menu.

Water Resistance

Designed to be as functional as it is attractive, the Nivada Grenchen F77 offers 10 ATM water resistance. This makes it well suited to everyday water activities such as swimming and shallow-water diving. Every component, from the screw-down crown to the case structure, is carefully designed to resist water and pressure. A screw-down caseback further strengthens the watch's water-resistant seal. Paired with its precision, this durability makes it a smart choice for anyone who wants a watch that looks good and is ready for daily challenges.
