Angelus unites the chronograph's key functional scales—telemeter, pulsometer, and tachymeter—in a single design. True to its heritage as a maker of functional timepieces, Angelus brings together the expertise developed through its previous instruments in the Instrument de Mesures. Produced in two limited editions of 25 pieces, this watch is a genuine instrument of measurement, designed to calculate elapsed time, the speed of sound, distance travelled and heart rate. Using a single chronograph hand, it integrates three functions, each with its own dedicated scale. Housed in a 39 mm steel case, its three-dimensional dial is both highly legible and meticulously graduated, giving the Instrument de Mesures the character of an authentic tool watch with a distinctive vintage charm and singular identity.
One Instrument, Multiple Measurements
Integrating these three scales alongside the essential minute track required a particularly sophisticated design approach. The amount of information to be displayed, combined with the need for legibility and clarity, led Angelus to adopt a distinct colour code for each function. This arrangement is reinforced by a three-dimensional dial construction, featuring a domed centre and outer edge connected by a sloping intermediate section. The telemetric scale is situated on the highest level at the periphery of the dial. The pulsometer extends across the angled intermediate section, and the tachymeter, in the form of a spiral, is located closest to the hands.
The In-House A5000 Chronograph Calibre
The Instrument de Mesures is powered by Angelus's in-house A5000 chronograph calibre. Its classical architecture showcases numerous intricately shaped components, providing an ideal canvas for high-end finishing. Faithful to the great traditions of chronograph watchmaking, the A5000 incorporates a column wheel and a horizontal clutch, both defining features of traditional chronographs.
