Nivada Grenchen was a household name in the mid-century as it manufactured watches of all kinds from the 1920s through the 1970s. No other model from its lineup embodied this do-it-all ethos as strongly as the Chronomaster, a true Swiss army knife of Swiss watches. Designed to be a chronograph, aviation tool, and dive watch all in one, the Chronomaster is considered one of Nivada Grenchen’s signature designs and was chosen as a core model in the brand’s 2018 relaunch.
The Chronomaster’s 316L stainless steel case is 38mm across, 46.5mm lug to lug, and 13.75mm thick providing 10 ATM of water resistance. The Lollipop model features a matte black bi-compax dial with a prominent red lollipop chronograph hand in the center, while the “Orange Boy” variant sports a bold wedged orange chronograph hand. On the edge of the dial is a tachymeter scale, which is paired with a no-click bi-directional dive bezel. The Chronomaster features 20mm lugs and can be configured with a variety of vintage-inspired leather straps, rubber tropic straps, and bracelets.
Powering the Chronomaster is the Sellita SW510 M BH B, a manually wound two-register chronograph movement with 63 hours of power reserve. It features running seconds at 9 o-clock, elapsed minutes at 3 o-clock, and a stopwatch seconds at center. The caseback is solid and brushed, while the front is protected by a double domed sapphire crystal.
