H. Moser & Cie.’s Endeavor Tourbillon Skeleton

The 40mm red gold timepiece features a fully openworked movement, where all non-essential materials are carefully stripped away, leaving only what is absolutely necessary.

The fully skeletonized — and fully visible — HMC 814 is an automatic, three-dimensional calibre designed to have exceptionally open bridges to allow more light to traverse the entire watch and highlight the in-house one-minute flying tourbillon and patented double hairspring.

Visible through the caseback, the movement’s gold skeletonized oscillating weight contrasts alluringly with the dark main plate and bridges with anthracite PVD finishing. The refined timepiece boasts a 72-hour power reserve.
