Independet Swiss Watchmaker. 

Our journey began in 2009 with the opening of our fully integrated Manufacture in Biel. Under the leadership of watch enthusiast Serge Michel and master watchmaker Claude Greisler, our goal was clear: to create innovative, high-quality timepieces in-house, rooted in Swiss-German watchmaking tradition yet elevated through our self-developed movement concepts. From day one, we’ve embraced an openwork design approach with our watches, a design-aesthetic that we call “transparent mechanics”. Why? Because we want to highlight the labour, precision, and dedication poured into each piece—a true reflection of our timepiece-manufacturing philosophy: the science of movement. This scientific ethos has shaped our watches and formed the foundation of our distinct design language, which is evident across all our product lines. Each watch we create is hand-crafted, with nearly all movement components made in-house.
