Writer Jamy Gourmaud spotted wearing a Tissot

French television personality turned writer Jamy Gourmaud — best known to generations of viewers as the enthusiastic host of science program C'est pas sorcier — was recently photographed wearing a Tissot T-Touch Expert Solar, identifiable by its vivid orange rubber strap and matching orange applied indices and hands against a grey tactile dial. The sighting aligns neatly with Gourmaud's everyman-intellectual image: technically serious hardware worn without pretension.

The Tissot T-Touch Expert Solar T091.420.47.051.01 sits at the top of the T-Touch family, introduced in 2013 as the solar-powered evolution of the original touch-screen T-Touch launched in 1999. Its 47 mm titanium case houses a Tissot Caliber T151, a solar-quartz analog-digital movement that charges via photovoltaic cells integrated beneath the anti-reflective sapphire crystal — a genuinely clever piece of engineering that eliminates battery replacement entirely. A full charge delivers approximately a year of autonomy in the dark.

The tactile sapphire bezel is the watch's signature party trick: press it at any of the function markers — METEO (weather trend), ALTIMETER (up to 9,000 metres), COMPASS, CHRONO, TIMER, or ALARM — and the watch activates the corresponding sensor, displaying results on the lower digital sub-register. It is Swiss Made, water resistant to 100 metres, and weighs a featherlight 69 grams thanks to the grade-2 titanium construction.

From a collector standpoint, the T-Touch Expert Solar occupies a pragmatic niche: it is not a luxury watch in the traditional sense, but it is one of the most functionally complete outdoor instruments available at its price point, outperforming far more expensive rivals in raw utility. The orange variant in particular has developed a loyal following among hikers and adventure-oriented professionals who appreciate the high-visibility colour scheme.

At an official retail of around $875 USD, the T-Touch Expert Solar represents exceptional value engineering. Grey-market prices hover close to retail, reflecting steady demand rather than speculative interest. For Jamy Gourmaud, a writer and communicator who built a career demystifying science for the public, wearing a solar-powered, titanium multi-sensor watch on his wrist feels less like a style choice and more like a natural extension of his worldview.
