Exuding clarity, classicism and refinement, Prestige HM features off-centre hours and minutes, superlatively hand-finished, in-house movement, graceful case and ergonomic case back crown.

Inside the chapter ring of the 18k gold dial, the smooth-finished, off-centre hours-minutes subdial bearing the R. Gauthier logo is flanked either side by a gorgeous guilloche that shimmers in the light. The dial elements are fixed invisibly from beneath, lending the displays a delightful purity.

The graceful case is distinguished by clean, unbroken lines around its perimeter, with the absence of a ‘normal’ crown revealing just how remarkable the movement is.

By placing the crown flat on the case back, Romain Gauthier has increased winding efficiency since energy no longer needs to be transmitted through 90°, while the large diameter and undulating profile of the crown enable Prestige HM to be effortlessly wound, even while on the wrist.

Turning over Prestige HM, the wearer can admire the finely-finished Calibre 2206 HM through the display back. This movement was conceived, developed, produced, decorated, assembled and regulated at Manufacture Romain Gauthier in the Vallée de Joux, Switzerland.

Virtually every component of the movement bears Roman Gauthier’s distinctive touch. The bespoke gear wheels feature circular arms providing elegance and strength. The polished screw heads bear an aesthetic S-slot that enables more torque to be applied during assembly. The regulator boasts a Romain Gauthier-designed balance wheel featuring distinctive curved arms and calibrated eccentric weights, as well as a high-efficiency triangular pallet lever, another Romain Gauthier invention.

The large movement bridge with a cut-out and the Vallée de Joux style finger bridges around the bottom catch the light and the eye with their polished, rounded bevels that have been meticulously created by hand. Such anglage is the hallmark of superlative hand-finishing, for which Romain Gauthier has become renowned.

The jewel countersinks are also hand-made and hand-polished, while the mainplate recesses are decorated with spotting (perlage). As many as 60 hours have been devoted to hand-decorating the movement – even those components that are not on show.

Prestige HM has been created in four 38-piece limited editions: 18k white gold, 18k red gold with black dial, 18k red gold with champagne dial and 950 platinum.

Prestige HM with diamond-set bezel – featuring 60 baguette-cut diamonds totalling 3.86 carats set into the bezel – has been created in four 8-piece limited editions: 18k white gold, 18k red gold with black dial, 18k red gold with champagne dial and 950 platinum.
