Cyril Favre
Founder & Watch Analyst
Cyril Favre is the founder and sole analyst behind 10h09. Over the past five years, he has catalogued more than 4,000 mechanical and quartz watches — measuring, photographing, and scoring each one across 35 style and value dimensions. He built the 10h09 matching engine to answer one question he kept asking himself: which watch actually fits me, not just which one is popular? He writes under a pen name to keep the focus on the watches, not the person. Every recommendation is backed by a public methodology anyone can audit.
