Tissot PRC 100 Solar Quartz 39mm Mens Watch Silver

Ref. T1514221103100

The PRC 100 has been part of Tissot's T-Sport catalogue since the mid-2000s, and this 2025 revival makes a pointed update: out goes the conventional battery, replaced by the ETA F06.615 Lightmaster movement, which draws charge from a honeycomb-patterned solar cell woven into the dial. The practical gain is a 14-month power reserve and the end of battery replacements. When charge runs low, the seconds hand shifts to four-second jumps — a useful alert that requires no digging into a manual. At 39mm and 9.22mm deep, it sits neatly under a cuff and wears across a range of wrist sizes without the bulk that some sport watches carry. The dodecagonal bezel is the most distinctive element of the design, giving the case a faceted geometry that reads differently from a plain round profile without announcing itself. The butterfly clasp makes daily on and off straightforward.
