By launching the Angelus x Massena LAB Medical Chronograph from the new La Fabrique collection, the iconic Swiss watch brand revives its legacy in manufacturing doctor’s watches.
Created in collaboration with Massena LAB, the Chronographe Médical is limited to 99 pieces. Endowed with dual pulsometer and asthmometer scales, it is a true tool watch for medical professionals. This model also marks the beginning of a new Angelus collection named La Fabrique created specifically for tribute editions.
In the 1960s, Angelus launched a wrist-worn hand-wound chronograph for doctors and medical professionals. Its unique style dial featured a dual scale for a pulsometer to measure the patient’s pulse and an asthmometer to record the respiratory rate. This doctor’s watch has been brought up to date by Angelus to appeal to modern tastes.
Movement
The Chronographe Médical x Massena LAB houses the Angelus manual winding A5000 movement with integrated mono-pusher chronograph.
It has a small seconds dial at 9 o’clock. The chronograph seconds hand placed on the centre can be used for calculating heart rate or respiratory rate in reference with the respective scales. Equipped with a single mushroom-shaped pusher at 2 o’clock and operating at a rate of 3 Hz, the Angelus A5000 chronograph calibre incorporates a column wheel and a horizontal clutch.
The case is made from 316L steel. Lastly, the case diameter has been increased to 39mm to make the pulsometer scale more legible.
Pulsometer
The pulsometer function indicates a patient’s heart rate without the need for calculations. On the Angelus Chronographe Médical, the pulsometer scale between 1 and 3 o’clock is based on 10 beats. As soon as the chronograph is started, simply count 10 beats, then stop the mechanism. When compared against the pulsometer scale, the chronograph hand will then indicate the number of beats per minute.
Asthmometer
The asthmometer displays the respiratory rate per minute. The Chronographe Médical works on the basis of five breaths. After starting the chronograph, count five breaths before pressing the pusher again. The chronograph hand will indicate the number of breaths per minute on the inner scale graduated from 40 to 10.
Dual Pulsometer and Asthmometer Scale
The pulsometer scale of this watch has a very specific colour code: green, black, or red, corresponding to the severity of the reading obtained during the examination. By contrast, the respiratory scale is red and is nestled inside the minute circle. These two scales are positioned so as to make them as legible and clear as possible. Before each scale, the requirement for taking vital signs is listed (base 10 pulsations and base 5 respirations).
The font used is particularly wide and contrasting. Two large arrows accentuate these scales, one of which, curved and crossing the minute circle, is completely unique. Lastly, the silvered opaline dial and Dauphine hands with luminescent lines are identical to the model that inspired this timepiece. The dial has 12 appliqué hour markers: six indexes and six Arabic numerals.
To give more importance for the pulsometer and asthmometer scales, the minute track and the hour markers have been pushed in towards its centre.
The watch comes fitted on a full-grain golden brown calfskin Novonappa® strap.
Limited to 99 pieces, Chronographe Médical x Massena LAB will be available through the network of authorised Angelus retailers. The watch will also be available directly from MassenaLAB.com.
