Introduction
Inspired by their 1960s doctors watch, Angelus collaborated with Massena Lab in 2023 to create a limited edition faithful re-interpretation of their early medical chronograph, limited to just 99 pieces. Boasting an opaline silver dial with a dual scale for reading the vital signs doctors need during patient examinations: a pulsometer – to measure the patient’s pulse – and an asthmometer – to record their respiratory rate, this timepiece pays homage to the mid-century trend of watchmakers creating specialized chronographs to meet specific functional or professional requirements. Increased in size to 39mm to make its dial mor legible, the ref. 0.CHAS.A01A that we have here takes a mid-century inspiration and injects it with a modern sense of design. Powered by the manual-wind cal. A5000, this timepiece offers the finest level of watchmaking Angelus has to offer, with its small seconds subdial residing at 9 o’clock so as to leave the asthmometer uninhibited.

THE DIAL
Featuring a silver dial with two medically-relevant scales, a pulsations scale, and a respirations scale (asthometer), the Chronographe Medical pays homage to the important uses that doctors had for chronographs back in the early days of wristwatches.

THE CONSTRUCTION
Made of medical-grade stainless steel, the Chronographe Medical's 39mm case lacks any distracting embellishments that would otherwise take away from its role as a potentially life-saving tool watch.
