Tissot PRC 100 Solar Quartz 39mm Mens Watch Black

Ref. T1514223305100

The PRC 100 has been part of Tissot's sportswear line since the mid-2000s, and this 2025 iteration marks its most significant update: the dial's honeycomb structure is not purely decorative but houses photovoltaic cells that charge a rechargeable accumulator, good for up to 14 months on a full reserve. Ten minutes in direct sunlight at around 5,000 lux adds roughly a day of running time, and an end-of-energy indicator warns before the watch stops entirely. It is a genuinely practical arrangement for a watch worn daily and rarely thought about. At 39mm across and 9.22mm thick, it sits closer to a dressed sport watch than a chunky tool watch, and the 44.6mm lug-to-lug means it will fit a wide range of wrists without the dial hanging over the edges. The all-black PVD across both case and bracelet reads as a unified piece rather than a case dropped onto a mismatched band, and at 128g the bracelet has enough substance to feel considered without becoming heavy through a long day.
