There’s a reason why the small second dress watches of the 1940s and ‘50s still impress today. Elegant and understated, they could be worn anywhere, anytime. It was their timeless looks that inspired the retro-temporary style at the heart of the TRIBUS collection.

One of our first releases, the TRI-01 Small Second Chronometer captures the TRIBUS handwriting in its purest form, where vintage feel and modern flourishes combine. Its dial looks effortlessly impressive, with a smoothly concaved subdial and the inclusion of luminous hands makes for easy reading in the dark.

The TRI-01’s case has been sculpted from stainless steel; we chose to engineer each one in Switzerland, utilising the country’s reputation for world class detail and precision. Through its exhibition backplate, you can witness another piece of art: its Swiss-made Sellita SW261 movement.

Each SW261 movement has been chronometer-certified. Only once they’ve passed a number of tests in different positions and temperatures are they deemed precise enough to feature in the TRI-01 collection. Accurate to within -4/+6 seconds a day, the TRI-01 sits in the top 6% of all Swiss-made watches for timekeeping. Because only the best will do.
