For Christmas time, Swiss luxury watch brand CORUM pays tribute to its classical collection Romvlvs, by revealing an exceptional jewellery timepiece, bearing a tourbillon movement crafted on sapphire plate and bridges.
Introduced by CORUM in 1966, the Romvlvs model makes reference to watchmaking art in its purest form, and has made its mark on watchmaking history. This model is in fact the first watch to display a dial without hourmarkers and having the index engraved on the bezel. Interpreting the classical codes of the brand, the Romvlvs collection was enriched in 2008 by two major complications: a perpetual calendar and a retrograde annual calendar. In 2010, CORUM pushes technical boundaries to their limits by offering a Romvlvs Billionnaire Tourbillon demonstrating the brand’s remarkable talents.
Ultimate expression of refinement and brilliance the Romvlvs Billionaire Tourbillon stages the tourbillon movement crafted in sapphire bridges and plate in an amphitheatre of diamonds. Endowed with a 90-hour power reserve, the tourbillon prevailing on its sapphire crystal throne is a truly exceptional creation. The mainplate and the three bridges are made of sapphire crystal, a very delicate and brittle material.
Framing the movement like a genuine work of art, the white gold case is set with 164 diamonds, accentuating the precious appearance of this exceptional timepiece. True to the aesthetical codes of the Romvlvs collections since 1966, the bezel bears the Roman Numerals drawn by 44 baguette diamonds using the invisible diamond setting technique. At the heart of this diamond fairy of 4.7ct, this stunning movement is beating at 21,600 vibrations per hour. Water-resistant to 30 meters, the inimitable cambered case typical to the Romvlvs, measures 45mm.
Manufacturing the Romvlvs Billionaire Tourbillon calls for extreme precision and high-end watchmaking knowledge, a CORUM signature available in a limited production of 5 pieces only.
