AN ICON THAT NEVER STOOD STILL
Because great design doesn’t age, it evolves. The F77 emerged in the 70's with a strong identity, returned through MKI and MKII with renewed precision, and now expands into a broader collection. An icon, no longer limited to one expression.
F77 VINTAGE PIECE FROM THE 70’S
The 1970s gave rise to a new aesthetic in watchmaking one that fused form and function, luxury and sport. The F77 was Nivada Grenchen’s answer to that trend. With its faceted case, integrated bracelet, and bold dial textures, it stood proudly among the avant-garde steel sports watches of its generation.

F77 OPEN HEART
F77 MKII STONES DIAL
F77 MKII TRESSED DIAL
FORGED IN SPACE,
REVEALED ON EARTH
A REAL PIECE OF METEORITE
Imagine an object falling from the silence of the stratosphere, shaped by speed and friction.
This vision inspired the F77 Open Heart. Its fractured dial reveals the movement beneath, like a core still burning from re-entry.
WHERE THE SURFACE OPENS, THE HEART TAKES OVER
This edition takes the iconic F77 and pushes it into a new realm.
The dial opens to reveal the movement beneath, giving the watch a living, breathing presence on the wrist.
Available in Matte Black, Natural Aventurine Green, and a real Meteorite, the F77 Open Heart combines Grade 5 titanium, sculpted apertures, and Swiss mechanics to create a bold evolution of the model.
TITANIUM GRADE 5
Renowned for its exceptional strength and lightweight properties, Titanium Grade 5 sets the standard for durability and comfort in watchmaking.
With a composition of approximately 90% titanium, 6% aluminum, and 4% vanadium, this alloy offers unparalleled performance and resilience.
A WATCH THAT FEELS ALIVE
THREE FACES OF THE OPEN HEART
A TRIO BORN FROM CONTRAST
Matte Black, Aventurine Green, and Meteorite each reinterpretthe fractured dial in their own language.
Black brings depth and contrast, Aventurine creates a cosmic glow through the fissures, Meteorite introduces raw celestial texture.
Together, they form a trio that transforms light, shadow, and movement in completely different ways
LIGHT TROUGH THE FRACTURE
LIGHT THROUGH THE FRACTURE
The F77 Open Heart is designed to glow from within. Applied indexes and hands are enhanced with crisp white Super-LumiNova, ensuring precise legibility in low light.
On the Green Aventurine version, luminous material is placed beneath the dial itself, allowing light to diffuse subtly through the fractured openings.
FEATURES
For this Open Heart edition of the F77, we crafted a Grade 5 titanium case paired with a fractured dial that reveals the movement beneath.
Available in three dial executions, it features a double-domed sapphire crystal and an exhibition caseback that highlight the depth and modern direction of this creation.
THE STORY CONTINUES
ON THE BACK
THE STORY CONTINUES
ON THE BACK
The exhibition caseback completes the Open Heart experience, revealing the Swiss-made SOPROD M100BV in motion. Through the sapphire crystal, the bridges, gears, and oscillating weight come to life echoing the visible balance at 6 o’clock on the dial side.
Beating at 28,800 vph (4Hz) with a 42-hour power reserve, this automatic caliber is derived from the proven A10 architecture, combining precision, reliability, and modern mechanical depth for the F77 MKII Open Heart.

THE F77 MKII STONE DIALS LINEUP
GREEN AVENTURINE
A Ventura Born
of Chance
Green aventurine is known as the stone of opportunity, a symbol of optimism, vitality, and quiet confidence. Its natural shimmer (aventrurescence) catches the light with a refined sparkle, elevating everyday moments without shouting for attention.
LAPIS LAZULI
Earthborn Beauty,
Celestial Soul
Lapis lazuli isn’t just a stone, it’s Earth’s deep-blue history, formed over millennia and dusted with natural gold flecks. Celebrated for centuries in art and ornament, it keeps its intensity through time. Reimagined on the F77 dial, it delivers a bold, quiet presence on the wrist proof that the most cosmic wonders can be born right here on Earth.
DARK BLUE AVENTURINE
A Glimpse into
the Cosmos
Aventurine glass turns the dial into a night sky, deep blue, sprinkled with countless sparkling inclusions like suspended stardust. Rooted in a centuries-old glassmaking tradition, it proves that wonder can be crafted. Often linked to calm focus and positive energy, it adds meaning to the shimmer.
METEORITE
A Slice of the Sky
The meteorite used for this dial originates from the Muonionalusta meteorite, discovered in northern Sweden. Classified as an iron octahedrite, it contains approximately 7.65% nickel and belongs to a rare category of metallic meteorites, representing only about 5.7% of all meteorites that reach Earth.Formed in space over millions of years and revealed through acid etching, its distinctive Widmanstätten pattern, composed of kamacite and taenite bands, is the natural signature of its extraterrestrial origin.
