Angelus has spent decades developing complications with a practical purpose, and the Instrument de Mesures represents the most concentrated expression of that approach yet. From the alarm movements and eight-day calibers that defined its early reputation to the chronographs that earned it a place among collectors. The Instrument de Mesures continues that tradition and takes it a step further, consolidating three distinct measurement scales within a single 39mm steel case. The telemeter calculates the distance to a sound-producing event by timing the interval between sight and sound. The pulsometer delivers a heart rate reading from just 15 counted beats. The tachymeter, arranged as a spiral closest to the center of the dial, determines average speed over one kilometer across a range from 20 km/h to 500 km/h. A single chronograph hand activated by the pusher integrated into the crown reads across all three. The watch is produced in two limited editions of 25 pieces each, one on an ebony-black dial with blue, orange and cream scaled markings, the other on an ivory-white dial with blue, red and green.
What makes the Instrument de Mesures technically interesting is how Angelus resolved the legibility problem those three scales create. The dial is built in three dimensions, with a domed center, a sloping intermediate section and a raised outer edge, each level carrying a dedicated scale. Laser-cut markings sit subtly within the material rather than on top of it. Syringe hands reference the 1960s Angelus chronographs that anchor the design vocabulary here, and a box-shaped sapphire crystal gives the dial the depth it needs to read clearly under a range of lighting conditions.
The A5000 caliber inside is an in-house chronograph movement with a column wheel and horizontal clutch, both choices consistent with traditional chronograph architecture and the vintage spirit the watch projects. Palladium-treated elements on the chronograph mechanism contrast against the 3N gilded finish of the rest of the movement, visible through the sapphire case back. This is a watch that follows directly from the Chronographe Medical of 2023, the Instrument de Vitesse of 2024 and the GPHG-winning Chronographe Telemetre of 2025. Each of those pieces addressed a single measurement function. The Instrument de Mesures addresses all three at once.
