A New Light on Timekeeping: Introducing the Tissot PRC 100 Solar

With the release of the PRC 100 Solar, Tissot marks a new chapter in its pursuit of innovation. Anchored by its iconic dodecagonal bezel, the models bring nature and technology together, transforming solar energy into limitless power.

First introduced in the mid-2000s, the PRC 100 was recognised for its striking design, carving out its place in the Tissot collection. Today, it returns with a pioneering Lightmaster Solar Quartz movement, harnessing photovoltaic energy to fuel every second.
True to its name - Precise, Robust, and Classic - the PRC 100 Solar features a bold silhouette and a sunray dial that create a striking interplay of textures, giving the watch a strong presence on the wrist.

Available in two sizes, 34mm and 39mm, in a range of variations with leather or stainless steel bracelets, the Tissot PRC 100 Solar is an invitation to seize the day and every opportunity it brings - turning light into power and ambition into action, because the future belongs to those who dare to create it.

Following the Sun, Moving with Purpose

Like the sun's journey across the horizon, the Tissot PRC 100 Solar offers a spectrum of choices, each capturing a distinct expression of confidence. All five versions with a 39mm case bring their own presence, ready to move with you.

The stainless steel models come in two variations: a silver sunray dial that plays with reflections or a deep blue dial that captures depth and dimension.

For a more striking presence, the full-black model with a matching bracelet delivers undeniable character.

Meanwhile, two leather-strap options create contrast - stainless steel paired with brown leather, or full black with a smooth leather strap.
The PRC 100 Solar 34mm models mark a new dawn in the collection's evolution. With refined proportions and a luminous palette, designed for those who embrace their own radiance, these stainless steel, two-tone rose gold PVD or full yellow gold PVD models make their own statement.

When night falls, each Tissot PRC 100 Solar model continues to shine with Super-LumiNova®-coated hands and indexes that ensure visibility long after the sun sets, so time is always in sight.
Drawing energy from light, the PRC 100 Solar introduces a new era of innovation for Tissot. Equipped with a quartz solar movement and advanced Lightmaster technology, it absorbs both natural and artificial light as it passes through the sapphire crystal, where discreet solar panels convert and store it in a rechargeable accumulator.

Beyond its sustainable source, the movement's precision guarantees unwavering accuracy, while its optimised consumption extends power retention, keeping the PRC Solar 100 running far beyond its exposure to light.
