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. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOne instrument, several measurements\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003eWith its extensive metrological capabilities, this model remains  true to Angelus’s historical mission: creating the functional  complications that have forged its reputation among collectors. From  alarm watches and chronographs to eight-day movements, Angelus has  always designed its mechanics to serve a practical purpose and the  wearer's needs. \u003c\/p\u003e\u003cp\u003eThis new piece follows in the footsteps of the Chronographe  Médical of 2023, the Instrument de Vitesse launched in 2024 and the  Chronographe Télémètre, winner of the Chronograph Prize at the Grand  Prix d’Horologie de Genève in 2025. The Instrument de Mesures represents  the culmination of these earlier creations, bringing together their  three signature scales – a telemeter, a pulsometer and a  tachymeter – within a single watch. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTwo editions\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003eThe Instrument de Mesures is available in two limited editions of  25 pieces. The first features an ebony-black dial, with the scales  arranged from the outer edge towards the centre in shades of blue,  orange and cream. The second pairs an ivory-white dial with blue, red  and green markings. The finely grained surface of the dials is  complemented by syringe hands, a design signature directly inspired by  the 1960s chronographs that Angelus pays tribute to here. \u003c\/p\u003e\u003cp\u003eAt 39 mm in diameter, the steel case combines balanced  proportions with a slender profile. The twisted lugs flow naturally from  the case band, creating a fluid and harmonious silhouette. The bezel’s  simplicity gives the dial centre stage. And beneath a box-shaped  sapphire crystal, the generous dial opening highlights what makes the  Instrument de Mesures unique: its multiple graduated scales, designed to  provide a clear and intuitive reading of its various functions. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThree scales\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003eThe 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. \u003c\/p\u003e\u003cp\u003eThe various scales are straightforward to use. To measure an  event, just start the chronograph using the single pusher integrated  into the crown. A second press stops it at the end of the measurement.  The position of the central seconds hand on the corresponding scale  immediately indicates the result. Pressing the pusher a third time  resets the chronograph to zero, ready for a new measurement. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFour sections\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003eIntegrating 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. \u003c\/p\u003e\u003cp\u003eTo 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. \u003c\/p\u003e\u003cp\u003eDesigned according to a rigorous visual hierarchy, this  three-dimensional construction naturally draws attention to the  essential information. A functional approach that perfectly embodies the  vocation of the Instrument de Mesures as a true instrument watch  conceived above all as a tool for reading and measurement. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFive thousand \u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003eThe 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. The abundance of bevelled edges is a testament to the  Manufacture’s traditional craftsmanship. \u003c\/p\u003e\u003cp\u003eVisible through the sapphire case back, the chronograph mechanism  immediately draws the eye. Its palladium-treated elements stand out  strikingly against the rest of the movement, which has a 3N gilded  finish. This contrast emphasises the complexity of the construction and  highlights all the components involved in time measurement. \u003c\/p\u003e\u003cp\u003eFaithful to the great traditions of chronograph watchmaking, the  A5000 incorporates a column wheel and a horizontal clutch, both defining  features of traditional chronographs. A technical choice that combines  mechanical refinement, operating pleasure and fidelity to the vintage  spirit that defines the watch.\u003c\/p\u003e","brand":"Angelus","offers":[{"title":"Default Title","offer_id":47212233883819,"sku":"OCHDS.IO1A.V1477S","price":23600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/2783\/3515\/files\/5811167743.jpg?v=1781042183","url":"https:\/\/www.exquisitetimepieces.com\/products\/angelus-instrument-de-mesures-ivory-white-ochdsio1av1477s","provider":"Exquisite Timepieces","version":"1.0","type":"link"}
