Hours and minutes are clearly legible in a large sub-dial, while cut-outs in the main dial reveal the intricate workings of the precision micro-mechanics of the in-house manufacture movement beneath.

The visible oscillating balance wheel at 7 o’clock and open seconds’ wheel at 5 o’clock add vibrancy and animation to an already rich visual experience of mechanics, texture, colour and composition.

The elegant 41mm diameter case – available in red gold or platinum – is distinguished by clean lines around its full case perimeter, with the crown remarkably absent.

The Prestige HMS features the signature Romain Gauthier rear crown configured so that it is flat, flush against the case-back. Large in diameter, this crown enables the watch to be easily wound while on the wrist.

That’s because both timepieces feature the signature Romain Gauthier rear crown configured so that it is flat – flush against the case-back.

Romain Gauthier harnessed all his knowledge and experience of precision-mechanics to come up with this crown design that has manifold advantages over traditional caseband crowns.

Placing the crown on the back increases winding efficiency as well as water resistance. It also reduces wear and stress of components.

What’s more, the large-diameter flat crown enables the watch to be easily wound, even while on the wrist.

As well as these engineering advantages, there is also the aesthetic benefit of having the crown on the back, for the crownless perimeter of the case boasts graceful, uninterrupted lines that effortlessly catch the eye.
