F77 Tiger Eye bicolor MK1 where stone meets swiss precision

Some watches tell time. A rare few tell a story. The Nivada Grenchen F77 Tiger Eye Bicolor MK1 does both, and does them beautifully. This is the final edition of the F77 Mark 1, a closing chapter in the brand's modern history and a genuine collector's piece for those who understand what that means.

Anchored by a natural tiger's eye stone dial, dressed in a two-tone silver and gold stainless steel case, and powered by a Swiss automatic movement, the F77 Tiger Eye is neither a fashion watch nor a tool watch. It occupies its own space, warm, precise, alive, sitting at the intersection of vintage soul and modern discipline.

Steel, gold, and the earth between them

The F77 case is machined from 316L surgical-grade stainless steel, a material chosen not for compromise but for longevity. It resists corrosion, sits comfortably against skin, and holds its finish through years of daily wear. The two-tone silver and gold colorway adds a dimension that goes beyond aesthetic choice. It is a direct reference to Nivada Grenchen's vintage archives from the 1970s, when the brand produced bold dress-sport pieces that fused warm gold tones with cool steel in a way that felt both luxurious and sporty.

No two dials are identical. Yours will be your own

Applied silver indexes sit cleanly against the stone, each one carrying a small luminous dot that holds its glow long after the lights go out. The seconds hand sweeps at 28,800 vibrations per hour, smooth, steady, and hypnotic. The overall dial layout is uncluttered and legible, giving the stone room to breathe while maintaining the functionality expected from a daily-wear Swiss automatic watch.

Wearability is one of the F77's strongest arguments. The 37mm diameter and 45mm lug to lug measurement make it genuinely versatile across a range of wrist sizes. It disappears under a shirt cuff. It holds its own against an open collar. The two strap options extend its personality further. The 316L steel integrated bracelet is the signature choice, architectural and refined, while the canvas velcro strap introduces a sport casual register that transforms the watch entirely. Same movement. Same dial. Completely different energy.

Inside the F77 Tiger Eye is the Soprod P024, a Swiss-manufactured automatic movement that represents exactly the level of finishing and reliability this watch deserves. It beats at 28,800 vibrations per hour, offering the smooth sweep and timing accuracy that quartz cannot replicate. Its 38-hour power reserve means a watch worn regularly through a normal week will never stop unexpectedly. Take it off on Friday evening, pick it up Sunday morning and it will still be running.

Tiger Eye vs Tiger Eye Bicolor

The F77 Tiger Eye wears a full stainless steel bracelet. Every link is 316L steel, brushed and polished in the same alternating finish as the case. The overall effect is monochromatic and cool: silver case, silver bracelet, warm amber stone dial. The contrast comes entirely from the dial itself, the tiger's eye pulling all the warmth while the case and bracelet stay clean and neutral around it. This is the purer, more restrained interpretation of the watch.

The F77 Tiger Eye Bicolor MK1 changes the conversation the moment you look at the bracelet. Running through the center of each link is a gold-toned line, a two-tone detail that runs the full length of the bracelet from lug to clasp. The case carries the same two-tone silver and gold treatment, so the bracelet does not contrast with the case but extends it. The gold line in the links picks up the warmth of the tiger's eye stone and creates a visual thread that connects the dial to the band.
