Chronographs are traditionally among the heaviest watches on the wrist: more components, more case depth, usually steel. Polychrono solves that by building the complication in high-grade lightweight polycarbon, producing a fully functional chronograph that stays comfortable through all-day wear.
The Movement
Polychrono timepieces are driven by a premium Japanese quartz chronograph movement, specifically the Seiko Epson VR32 or an equivalent calibre. Quartz chronograph movements deliver precise elapsed-time measurement with the reliability and low maintenance the format is known for.
Reading the Three Sub-Dials
The dial layout uses three dedicated sub-dials: a 24-hour indicator, a chronograph 30-minute counter, and a running seconds display that confirms the watch is operating. Once the layout is familiar, all three read at a glance.
Built at 40.5mm
Polychrono models are crafted in a prominent, sporty 40.5mm case diameter, preserving the iconic octagonal bezel architecture. The size gives the multi-dial layout the space it needs to stay legible.
Everyday Resilience
All Polychrono models carry a standard water resistance rating of 5 ATM (50 metres), making them resilient to rain, splashes, and hand washing.
