Master watchmaker Vianney Halter has recently presented his latest achievement in this field with La Resonance, a timepiece which is the result of several years of research and development, preceded by models like the Deep Space Tourbillon in 2013 and the Deep Space Resonance in 2021.

La Resonance is a 3-hand, 35 grams light, round watch, regulated by two oscillators coupled by acoustic resonance which makes the two spiral-balance oscillators influence each other, quickly reaching a common frequency making the whole regulating system more accurate.

Defined by a 39 mm unibody titanium ring enclosed with 3 curved sapphire windows, the case has a minimalistic approach. The lugs, thanks to a small shoulder and bevel, are slightly set apart from the body. They are removable to allow for a complete restoration without altering any geometry.
The knurled crown at 9 o’clock allows the right caseband to be fitted with a sapphire window that reveals the beauty of the mechanisms and, more in particular, the heart of the acoustic resonance. 

Characterised by a truly unique architecture, the new caliber VH222 has no mainplate being made only with bridges and pillars.

All superfluous material has been trimmed down and each component is as thin and light as possible according to its function. The power is provided by two barrels that feed into a 55-part differential that splits the power so that the two balances receive the c...
