The hand-wound movement of the Master Tourbillon is a La Joux Perret calibre, beating at a cadence of 21,600 vibrations per hour with a power reserve of more than 90 hours. At 6 o’clock, the tourbillon carriage is attached to an 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 open-worked drum. The time-setting mechanism appears on the case-back. In addition to the traditional decorative finishes (hand bevelling, polishing, circular graining and Côtes de Genève), the letters RJ are engraved on the mainplate.





The Master Tourbillon dial features a complex split-level construction and comprises eleven parts in addition to the hour-markers. Around the rim, the sloping bezel ring is enhanced with applied tee-head shaped hour-markers. The stylized applied letters of the RJ logo under the brand name are in gold and the blued steel open-work hands are coated with white Superluminova C1.
The complex case adopted by Romain Jérôme 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 impeccable quality finishing, the casing ring is an integral part of the gold case-middle.

Golf Master Time watches are issued in Limited Editions of 50 in each gold colour.
