The Horological Machines 41.TSL.OW, seen from the bench

The HM4 represents MB&F's interpretation of the aeronautical watch concept, with a design that evokes aircraft turbines. The timepiece is equipped with the MB&F HM4 caliber that indicates hours, minutes and power reserve through laterally positioned displays. The case features a distinctive three-dimensional shape that houses the unconventional movement configuration.
