ROMAIN JEROME Master Tourbillon Limited Edition

The Master Tourbillon collection testifies to the superlative horological expertise of ROMAIN JEROME. It is based on a movement developed by masters of their art and aesthetically enhanced to correspond to the brand’s golf-themed identity.

The movement of the Master Tourbillon, distinguished by a level of fine craftsmanship that initiates will appreciate, may be admired from various angles. At 6 o’clock, the tourbillon carriage is attached to an exceptional and invisibly secured bridge. At 12 o’clock, the moon-crescent shaped opening reveals the wolf’s tooth ratchet-wheel and provides a bird’s eye view of the mainspring housed within an openworked drum. The time-setting mechanism appears on the case-back.

The quality of the finishing is heightened by the pleasure of seeing the movement in operation. In addition to the traditional decorative finishes (hand bevelling, polishing, circular graining and Côtes de Genève, the letters RJ are engraved on the mainplate. This hand-wound tourbillon, a refined version of a La Joux Perret calibre, beats at a cadence of 21,600 vibrations per hour and has a power reserve of more than 90 hours.

The Master Tourbillon dial features a complex split-level construction and comprises eleven parts in addition to the hour-markers. The opening at 12 o’clock, on which the club-style striped motifs echo those on the tourbillon bridge, enables one to appreciate certain specific features of the movement. Around the rim, the sloping bezel ring is enhanced with applied tee-head shaped hour-markers. The stylised applied letters of the RJ logo under the brand name are in solid gold and the blued steel openworked hands are coated with white Superluminova C1.

The complex case adopted by ROMAIN JEROME for its entire range of creations – thirteen parts assembled with no visible screws and featuring golf-style inserts on the lugs – clothes the Master Tourbillon in pink or white gold, with a bezel that is either polished or set with brilliant-cut and trapeze-cut diamonds. The watch also has a dimpled golf-ball type crown as well as sapphire crystals with multilayered anti-reflective treatment on both sides. The case cover carries the engraving of the model number within the limited series.

Its modular nature means that individual parts may be modified or replaced as necessary, such as following an accidental impact, either by restoring them to their original state or by giving them a different finish. To ensure maximum precision and impeccably quality finishing, the casing ring is an integral part of the gold case-middle.

The mississipiensis alligator leather strap, cut from large square scales, is hand-sewn and comes in a choice of colours: brown, green, black or white. Fashioned from solid gold matching the colour of the case, the double folding clasp with safety push-piece shaped like a golf club ensures perfect fit and comfort during all sports activities.
