Abstract
Using micro-manufacturing techniques inherited from the microelectronics industry, it is possible to batch process with a micrometric precision, centimeter scale silicon parts featuring extremely fine mechanical functions. High precision mechanical watch can particularly benefit from this approach which fosters the emergence of novel ideas and allows their concretization at the watch scale. CSEM has always played a pioneering role in this field and aims at becoming the Swiss Competence Center for the design, manufacturing, assembly, and characterization of hybrid silicon based innovative watch micro-mechanisms. In the Frame of the SILOSCAPE MIP, a novel escapement has been invented, designed, produced and integrated in a watch caliber; its functionality has been validated through a first characterization campaign.
