Manufacture Royale 1770 Steel with Openwork Skeleton Dial

Named 1770 after the year Manufacture Royale was founded, this timepiece newly embodies the daring and excellence which define the Manufacture.

Its restrained and thoughtfully elaborated form is the continuation of a generous and creative style, though contours have been softened and remodelled to propose a watch that is both sober and contemporary. Entirely developed and manufactured in-house, its haute horlogerie movement incorporates a splendid flying tourbillon.

The new MR03 calibre inside the 1770 watch showcases one of watchmaking’s most refined technical sophistications: the flying tourbillon. This aesthetically pleasing and visually spectacular construction leaves the observer free to admire in all its splendour the movement of the escapement and the superlative finishing of its parts.

An essential component since it determines the watch’s precision, here the escapement embraces the ultimate innovation with a pallet fork and escape wheel in silicon.

Thanks to its resistance to variations in temperature and to magnetic fields, among other qualities, silicon makes an important contribution to the movement’s performance. In this instance, the calibre also incorporates a screwed balance and a flat balance spring.

The flying tourbillon, which makes one revolution in 60 seconds, is positioned asymmetrically at 7 o’clock. This unconventional choice creates a unique visual tension that gives the watch all its personality. In addition to hours and minutes, the 1770 incorporates a power-reserve indicator for autonomy of 108 hours or four and a half days. Comprising 208 parts, the MR03 is hand-wound.

In an openwork slate-coloured version, the 1770 offers a striking and contemporary look. Its various levels lend a bolder technical dimension and offer glimpses of the movement with different forms. The sword shaped hands are partly satin-finished and partly polished for easy legibility.

Manufacture Royale is also known for the complexity and immediately identifiable design of its watches’ exteriors. Comprising a great many carefully executed and hand-finished parts, they are constructed in accordance with a pre-defined principle: the movement is housed inside a case, which in turn is contained in a sometimes mobile structure.

A hallmark of Manufacture Royale, this principle is captured in its essence by the 1770. Two beautifully proportioned brancards hug the case. Secured by functional, visible screws, they extend beyond it, and then gently curve to form the lugs.

The crown is polished with the initials “MR” engraved in its centre. The back of the case is entirely open to reveal the splendour of the movement.

Alternating polished, straight-grained and satin finishes, the exterior of the 1770 watch is a consummate example of Swiss haute horlogerie in both its aesthetic, imagined by the acclaimed watch designer Eric Giroud, and the flawless crafting and finishing of its parts. Made from 20 separate elements, the steel case measures 43mm in diameter.
