Every time Tissot launches something new, it captures my attention. Each release brings something fresh to the table—whether in terms of aesthetics, reliability, or technological innovation. Sometimes, it’s a combination of all three. That is exactly the case with the new PRC 100 Solar models, which combine appealing design, high accuracy, and a clear commitment to sustainability. But let’s take things from the beginning.
The idea of converting light into everyday, reliable energy feels more relevant today than ever. Watches that do not rely solely on mechanical precision, but instead align themselves with the natural rhythm of the world around us. Based on this philosophy, Tissot enriches the PRC 100 Solar collection with new models that bring a familiar design into the present, using solar energy as their driving force. With clean geometric lines, a distinctive dodecagonal bezel, and a power reserve that reaches up to 14 months in complete darkness, the PRC 100 Solar tells a contemporary story of precision, durability, and discreet technological innovation.
The PRC 100 is not a new watch. It made its debut in the mid-2000s, at a time when geometry and robustness played a leading role in watch design. Today, it returns refreshed, retaining the dodecagonal bezel—an unmistakable signature of the collection—and the characteristic sunray dial, which interacts with light and creates subtle visual effects as it moves. Its aesthetic balances structure and fluidity, industrial precision and natural variability.
Three new additions now join the PRC 100 collection. The two-tone 34 mm model, with a yellow gold PVD case and silver dial, is aimed at those seeking elegance in more restrained proportions. The corresponding 39 mm version maintains the same finish, creating a “twin” that functions almost as a dialogue between size and presence. It’s a great idea for a couple who want to wear matching watches.
Completing the range is a stainless-steel PRC 100 Solar in 39 mm, featuring an ice-blue dial, a cool, luminous shade that recalls the 34 mm model released in 2025, this time presented in a more commanding size.
Beneath the sapphire crystal, discreet solar collectors capture both natural and artificial light, storing it in a rechargeable accumulator. The result is impressive: up to 14 months of autonomy in complete darkness, without any exposure to light. This feature not only represents a technological achievement, but also turns the PRC 100 Solar into a genuinely practical tool for everyday use.
The watch’s functionality does not stop when the sun goes down. The hands and hour markers are coated with Super-LumiNova®, ensuring excellent legibility in the dark. The quartz movement delivers the accuracy one expects from Tissot, while optimized energy consumption enhances the sense of long-term reliability and endurance. The three-year warranty simply seals this philosophy.
As a whole, the renewed PRC 100 Solar collection speaks of discipline, resilience, and quiet strength. It does not seek to impress through excess, but through consistency. It captures light, transforms it into energy, and ultimately into time. And in doing so, it becomes part of a broader narrative—our everyday relationship with time and rhythm.
Prices: €495 (steel 39mm), €545 (two-tone models 34mm and 39mm)
