F77 Titanium Green Aventurine Open Heart MK2 Watch - 38mm 68051A77

The Watch

With the F77 Titanium Green Aventurine Open Heart MK2 watch, the Swiss brand Nivada Grenchen brings together sophistication and advanced engineering. Its octagonal Grade 5 titanium case offers exceptional strength while remaining remarkably light. At 38 mm in diameter and 12.20 mm thick, the watch fits comfortably on the wrist. Titanium adds durability and feels pleasant against the skin. The case pairs a brushed, satin matte finish with polished details for striking contrast. Its dominant gray and green tones give the design a distinctive modern look. Made for those who want a sturdy watch with the lightness and sophistication of European titanium, it also offers 10 ATM water resistance for a practical balance of elegance and performance.

The Dial

The dial is a visual standout, featuring aventurine, a semiprecious stone with shimmering reflections and a deep green color. An elegant open-heart design reveals part of the watch's movement, showcasing Swiss precision. The hands and hour markers feature SuperLuminova for easy reading in the dark. A minute track around the dial adds a refined detail. Protecting this jewelry piece, a domed sapphire crystal with an anti-reflective coating keeps the time easy to read, even in bright sunlight. Blending tradition and technology, the dial is central to the watch's design and invites admiration for both its looks and function. The transparent, screw-down caseback is made of titanium, reflecting the quality and authenticity of the craftsmanship.

The Movement

At the heart of this watch is the robust, reliable Swiss automatic SOPROD M100BV caliber. Beating at 28,800 vibrations per hour, it delivers smooth, precise timekeeping. A 42-hour power reserve keeps the watch running through a night or weekend off the wrist without needing to reset the time. Made in Swiss workshops, the caliber features an intricate architecture and meticulous finishing. Components visible through the open-heart aperture add a detail watch enthusiasts will appreciate, pairing visual appeal with performance. As it tracks the hours, minutes, and seconds, every beat reflects a tradition of attention to detail and reliable operation.

The Bracelet

The Nivada Grenchen F77 offers two bracelet options to suit different tastes and occasions. The first bracelet is made of titanium with a brushed steel finish, complementing the gray tones and giving the watch a subtle, sporty character. The second is fully adjustable with a Velcro closure, offering a more casual, practical alternative for active days and outdoor activities. The custom-sized lug width ensures a precise fit with either option. Both options feature a folding clasp for a secure, lightweight feel on the wrist. This choice of customization caters to traditionalists and fans of modern technology alike without compromising the watch's cohesive look.

Water Resistance

Built to modern watch standards, this Nivada Grenchen offers 10 ATM water resistance, equivalent to pressure at a depth of 100 meters. That makes it suitable for swimming and surface water sports. A screw-down crown adds protection against water intrusion. Equally at home on city streets and around the water, the watch pairs the elegance of a timepiece with the practicality of an adventure companion. Whether you face an unexpected splash or a busy day, its Swiss-made build offers a dependable blend of style and strength.
