Nivada Grenchen Watch: Aquamar Black

NIVADA GRENCHEN Aquamar: A vintage diver with reversible indices

The Nivada Grenchen Antarctic Diver Aquamar Black adopts the aesthetic of 1960s divers, revisited with a modern touch. Its brushed and polished 316L steel case measures 38 mm in diameter, 12.9 mm thick, and features a 45 mm lug-to-lug distance. The bidirectional bezel is adorned with a graduated black ceramic insert.

The matte black dial uses a "sandwich" construction with cut-out indices, revealing a luminescent date disc with dual Super-LumiNova that alternates between white and a patina tone depending on the position. The hands display a "cream latte" faux-patina charm.

The Nivada Aquamar is powered by a Soprod P024 automatic caliber (25 jewels, 28,800 vibrations/hour), offering a 38-hour power reserve, with hour, minute, central second, and date functions.

The model features a double-domed sapphire crystal with anti-reflective coating, a screw-down case back and crown (the case back is engraved with the iconic Antarctic penguin), and offers water resistance of 20 ATM (200 m).

This Black Aquamar is offered with several tool-free interchangeable straps: black or brown leather (with or without white stitching), Flat Link or beads-of-rice steel (no date), tropic rubber, or black Nato, all in 20 mm width.
