Gruppo Gamma – a very special microbrand from Singapore

Gruppo Gamma was founded in 2013, fuelled by a strong desire to design and build timepieces that can be appreciated by collectors and aficionados. Gruppo Gamma produces between 1,000 and 2,000 pieces a year and doesn’t enjoy scale efficiency as big companies do, but being small and independent Gruppo Gamma can focus on giving you the best ownership experience possible. Gruppo Gamma is here for the long haul and a significant portion of their earnings is re-invested into product development and aftersales support. No wonder, that the timepieces hold their value over time.

Retrospective maritime design language

Gruppo Gamma designs are retrospective, military and maritime. After all they are based in Singapore, a country surrounded by water and where fellow countrymen serve in the military. Nevertheless, best Swiss movements such as the ETA and STP caliber are installed. The strong case shapes and dial design with high level of finish gives the wearer of the watch a special feeling of retro and fine watchmaking. They are a microorganism of Singapore – small, with neither the tradition of old civilizations nor price-competitiveness of developing nations, but they are hardworking, passionate and have an eye for details.
