What to know
The Infinity Series Radiant extends J.N. Shapiro’s material experiments into a monopusher chronograph. Its brushed tantalum case measures 38mm across and 9.6mm thick. One dial combines meteorite with a heat-blued zirconium chapter ring; another uses guilloché zirconium across the dial and counter. Both versions are shown here.
Power comes from the hand-wound La Joux-Perret 5000-4, a column-wheel chronograph with a single control and a 30-minute counter. It runs at 21,600 vibrations per hour and provides 38 hours of reserve. June 2026 coverage described an initial run of 75 pieces. Unlike Shapiro’s Resurgence, this model uses a Swiss movement.
