MB&F’s HM5 was inspired by two 1970’s icons; the first high-performance supercars and the Amida Digitrend watch. Deceptively simple at first glance, the indications are inverse and reflected at 90° which are then magnified 20% thanks to an integrated optical prism. Upon a closer glance a second water-resistant case presents itself in order to guard the high-performance engine contained within. The bi-directional jumping hours and trailing minutes displayed by the reflective sapphire crystal prism is housed in zirconium with a stainless steel case. Limited to 66 pieces.
