Tissot PRC 100 Solar: Swiss Solar Technology Takes On Asian Dominance
Tissot Invests in Swiss-Made Solar Technology
Tissot has launched the PRC 100 Solar — the first analog quartz watch equipped with Lightmaster Solar Technology, developed entirely in Switzerland. In an exclusive interview with Monochrome, CEO Sylvain Dolla revealed the brand's strategy to compete with Asian solar dominance through homegrown innovation.
The Swiss Solar Challenge
For decades, solar watch technology has been dominated by Asian manufacturers. Tissot's partnership with CSEM in Neuchatel aimed to change that. "No such technology existed in Switzerland. Everything was Asian-based," explained Dolla. The result is a proprietary solar cell technology featuring microscopic honeycomb-structured cells integrated beneath the sapphire crystal.

From PRX Success to Solar Innovation
Tissot's PRX collection has been a phenomenon, with initial sales 20 times the forecast. The brand's strategy of focusing on 99 new references per year (down from 150) has allowed deeper investment in quality. The PRC 100 Solar represents the next chapter, combining Tissot's accessible pricing philosophy with cutting-edge Swiss solar technology.
As solar technology advances, Tissot's investment in domestic production could reshape the competitive landscape between Swiss and Japanese solar watches.
Sustainability Meets Watchmaking
The PRC 100 Solar aligns with Tissot's broader sustainability initiatives, including solar panels generating 105.25 MWh of energy for their facility and paperless digital catalogs. The Lightmaster technology eliminates the need for battery replacements, reducing environmental impact over the watch's lifetime.
