The Nivada Grenchen F77 MKI “Last Series” is the final run of the first-generation F77: four stone-dial variants, each reported as a numbered edition of 75. All share a 37 mm case, 45 mm lug-to-lug measurement and automatic Soprod P024 movement. It is distinct from the newer F77 MKII.
What “Last Series” means
Nivada Grenchen calls its Tiger Eye model “LAST SERIES MARK I” and describes it as the final edition of the F77 Mark I. The release followed the MKII’s debut earlier in 2025; the stone-dial editions serve as the first-generation watch’s send-off. The brand’s product page says the watch “closes a defining chapter in Nivada Grenchen’s history” and calls it “a true collector’s piece”—brand language, not an independent assessment. Nivada Grenchen’s F77 Tiger Eye Mark I listing and Time+Tide’s October 2025 release coverage describe the collection and its context.
Which F77 MKI Last Series variants were made?
Time+Tide identifies four configurations. It reports 75 individually numbered pieces per variation, based on Nivada Grenchen release information; Oracle Time also reports 75 pieces per model. Those are per-variant figures, not a separately stated total for the run.
| Variant | Case and bracelet finish | Dial |
|---|---|---|
| F77 MKI Tiger Eye | Stainless steel | Tiger Eye stone |
| F77 Tiger Eye Bi-Colour Mark I | Steel with yellow-gold PVD accents | Tiger Eye stone |
| F77 MKI Malachite | Stainless steel | Malachite stone |
| F77 MKI Green Aventurine | Stainless steel | Green aventurine stone |
The stones give the models different patterns and visual character, so the choice is primarily aesthetic. Bracelet and optional canvas Velcro strap configurations are described by the brand and Time+Tide; availability of a particular combination may vary by listing.

Is the Nivada Grenchen F77 MKI Last Series still available?
Current stock is not established across the four variants. The official product page and a dealer listing show that models have been listed, but a listing alone does not confirm present inventory. Chronoscout’s page records an extended sold-out period for the Malachite MK1 through its September 2026 observation; that is specific to Malachite and does not establish the stock status of the other variants.
Before buying, confirm the exact dial and finish, strap configuration, seller, regional price, current stock, warranty and return terms. The Chronoscout Malachite MK1 price and availability page is a third-party tracker, not a definitive inventory source for the full Last Series.
