About

Horological Machine N°1 is a highly innovative and totally original timepiece. HM1 features the world’s first movement with four barrels connected in both parallel and series, as well as the first wristwatch movement to have the energy transmitted to the regulating system from two sources simultaneously.

The three-dimensionality of the case and the sophisticated multi-strata of the dial both captivate the eye and challenge the mind. Within that structure beats a movement like no other: 376 parts, 81 functional jewels, 4 mainspring barrels, 7-day power reserve and an elevated central tourbillon.

Look deeper and you will discover that Horological Machine N°1 is more than a meticulously hand-crafted work of art, more than an intricate masterpiece of micro-engineering: it is a machine epitomizing the incredible passion and enthusiasm its collective of Friends dedicated to its creation.

Horological Machine No1 is delivered with a black hand-stitched alligator strap with a 18K Gold custom designed deployment clasp.

A bespoke pin-striped flannel and leather Etro carry bag holds the Wenge timber and leather presentation case.

set the time

Your watch is equipped with an automatic movement. If it has stopped, give the winding-crown (in the push position) a few turns clockwise.

The winding-crown has 2 positions:

1 Push position = normal position for wearing the watch.

2 Pull position = position for setting the time. Pull the winding-crown all the way out and turn the hands clockwise to set the desired time.
Then, don’t forget to push back the winding-crown against the case.

change straps

1 - Remove the screw on the right-hand lug by turning anticlockwise with the supplied dynamometric screwdriver.

2 - Remove the screw on the left-hand lug by turning anticlockwise with the supplied dynamometric screwdriver.

3 - Push the central pin out from between the strap and the lugs and remove the strap. Repeat steps 1-3 on the other side of the case.

4 - Place the new strap between the lugs and slide the central pin through lugs and strap.

5 - Screw-in the left and right-hand screws into the lugs by turning the dynamometric screwdriver in a clockwise direction. Take care not to force or over-tighten screws. Repeat steps 4-5 on the other side of the case.
