At the speed of sound
Measuring 37 mm in diameter, with a vintage-inspired dial and a monopusher set into the winding crown, this short-interval timekeeping instrument pays countless tributes to Angelus’ rich history, particularly its speciality in crafting chronographs. Its noble hand-wound mechanism, historical roots and superior finishes give this chronograph a wildly elegant retro aesthetic.

Distance and time
A telemeter is a type of measurement scale associated with a chronograph’s sweep seconds. Other categories in this family include pulsometers, tachymeters, decimal scales, fixed or rotating countdown scales, and asthmometers, which are a speciality of Angelus. Telemeters measure the distance to an event. To use a telemeter, the chronograph is started when the event is observed and stopped when the sound of the event reaches the observer. The scale is finely graduated in kilometres and calculates the distance based on the time interval divided by the speed of sound, which is approximately 1,240 km/h.
Body and face
With a diameter of 37 mm, the Chronographe Télémètre is the smallest contemporary Angelus model. The case middle presents characteristic curves that run from lug to lug. The polished edges, plunging at the top and twisted on the flanks, highlight the complex shape of the lugs. These dynamic details contribute to the characteristic vintage signature of the timepieces in the La Fabrique collection.
The satin-finished flange echoes the finish of the case and contrasts with the grained effect in the centre of the titanium grey dial. These finishes are illuminated by a delicate diamond-polished thread that separates the two areas. The small seconds and 30-minute totaliser counters are snailed, while the appliqué hour-markers and Arabic numerals have been given a 3N gold finish.
Heart and soul
The Chronographe Télémètre is powered by the in-house A5000 calibre. This chronograph movement, with an integrated mono-pusher, presents a two-tone finish: the elements of the mainplate and the bridges are golden-finished, while the components of the chronograph function are finished in palladium. The overall effect is completed by pronounced bevelling and stretching.
With its hand-wound movement and a 42-hour power reserve, the A5000 calibre is a highly versatile technical foundation for Angelus. Its regulating group oscillates at a frequency of 3 Hz (21,600 vibrations per hour), and the chronograph function is controlled by a column wheel with a horizontal clutch, just as it was in chronographs produced between the 1940s and early 1970s.
