Angelus Instrument de Mesures Ebony Black.

What is the new Angelus Instrument de Mesures?

The Angelus Instrument de Mesures unites the chronograph’s “three signature scales” – telemeter, tachymeter and pulsometer in a single watch. Renowned for functional watches such as alarm watches, chronographs and eight-day movements, Angelus’s Instrument De Mesures joins the brand’s Chronographe Médical (2023), Instrument de Vitesse (2024) and Chronographe Télémètre, the latter which won the Chronograph Watch Prize at the Grand Prix d’Horologie de Genève (GPHG) awards ceremony held in November 2025.

What are its dial features?

Right: Ivory White. “The telemeter gauges the distance to a sound-producing event by calculating the time elapsed between seeing it and hearing it. The pulsometer makes it easy to measure heart rate: simply count 15 beats to obtain a pulse reading. Finally, the tachymeter determines an object’s average speed over a distance of one kilometre. On the Instrument de Mesures the scale covers speeds from 20 *km/h to 500* *km/h.”*

The Ebony Black reference features an ebony-black dial with the three scales “arranged from the outer edge towards the centre” in blue (telemeter), orange (pulsometer) and cream (tachymeter).

The Ivory White reference features an ivory-white dial with the three scales (same sequence as the Ebony Black reference) in blue (telemeter), red (pulsometer) and green (tachymeter).

“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.”

“To achieve the necessary depth, Angelus implemented an innovative manufacturing process that involved laser-cutting directly into the material. The markings appear to emerge subtly from the dial, present without compromising legibility. 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.”

Both dial versions feature a “finely grained surface” and syringe-shaped hour and minute hands, the latter a tribute to 1960’s chronographs.

Is it powered by a column wheel chronograph movement?

Instrument de Mesures Ivory White. — Image: The movement is crafted by Manufacture La-Joux Perret S.A., which together with Arnold & Son and Angelus is essentially one entity. The main plate features a 3N gold finish and a circular-grained pattern. The bridges feature a 3N gold finish, Côtes de Genève and polished bevels. The wheels are circular-grained and the screws polished.

Yes. It is powered by Calibre A5000, an in-house manual winding movement with a column wheel and horizontal clutch that drives the central hours and minutes and 1-minute monopusher chronograph (enabling the wearer to obtain readings from the telemeter, tachymeter and pulsometer scales).

It measures 29.4 mm (diameter) * 4.2 mm (thickness), comprises 23 jewels, beats at a luxurious rate of 3 Hz or 21,600 vph and delivers a power reserve of 42 hours.

What are its case and strap features?

Its case is made from stainless steel and measures 39 mm (diameter) * 9.25 mm (thickness). Dial side features a box sapphire crystal with anti-reflective coating on both side and the caseback features a sapphire crystal with anti-reflective coating. Water resistant up to 3 bar or approximately 30 metres.

The Ebony Black reference comes with a black calf leather strap and the Ivory White reference with a tobacco-coloured calf leather strap. Both straps are fitted with a stainless steel pin buckle.

What do we think?

The triple scale design of Angelus’s Instrument de Mesures evokes much more of an “instrument look” than the typical two and three register chronographs. It is perfect for scientists, doctors, and race car drivers, maybe even pilots, for whom the readings of a telemeter, pulsometer and tachymeter scale is useful, often critical. It would be an ideal watch for Dr. Emmett “Doc” Brown the mad scientist in the 1985 cinematic epic Back to the Future! (It was followed by two sequels in 1989 and 1990).

The triple scale design is not so common. Patek Philippe had launched a limited edition triple scale chronograph (a handful of references, and not a monopusher) as part of its 175^th anniversary in 2014.

The Instrument de Mesures looks great in both its Ebony-Black and Ivory-White avatars, boasts wearable proportions, and is powered by a slow-beating column wheel chronograph movement. At 25 pieces each per reference (typical of Angelus) and a relatively accessible price, the Instrument de Mesures promises rarity, and allows a broader spectrum of collectors (they will need to act fast) to obtain this beautiful watch.
