Massena LAB Uni-Racer watches

The Massena LAB Uni-Racer is a hand-wound chronograph modelled on the Universal Genève Uni-Compax, the "Big Eye" chronograph Universal made from 1963 to 1965 and named for its oversized minute counter. It was the first watch Massena LAB released under its own name. The studio, founded in 2018 by the collector William Massena, began by working with independent watchmakers such as Habring².

The case is brushed and polished steel, a little larger than the 37 mm original, 13 mm thick and water resistant to 50 m, with a domed acrylic crystal and a solid steel caseback. Inside is the Sellita SW510 M, a hand-wound cam-lever chronograph built on the Valjoux 7760, itself a 7750 without the automatic winding. It runs at 28,800 vph with a 58-hour power reserve, and the oversized register counts 30 minutes.

The first two references, announced in October 2020, follow the two dials of the Uni-Compax: the UR-001 has a white dial, as on the original 884100/02, and the UR-002 a black dial, as on the 884100/01. Each was limited to 200 pieces.

In July 2021 Massena LAB added three colourways inspired by summer leisure, on the same case and movement and each limited to 35 pieces. The Cruise (UR-001-CRU) has a sunray-brushed indigo dial with aqua accents and red crosshairs. The Safari (UR-001-SAF) pairs a green gradient dial with khaki sub-dials. The Rally (UR-001-RAL), the sportiest of the three, has a sunray-brushed silver dial with blue counters, red crosshairs and a five-minute indicator on the 30-minute counter.
