Swiss luxury watch brand Ulysse Nardin has released two new versions of its LADY DIVER 39mm and BLAST TOURBILLON 45mm timepieces, both inspired by the iridescent rainbow colors of silicium.

In 2001, Ulysse Nardin became the first watchmaker to introduce a timepiece with silicium escapement components. Since then, the brand has incorporated this metalloid into several of its movements, including the BLAST TOURBILLON’s caliber UN-172 and the LADY DIVER’s caliber UN-816.

Inspired by the shimmering colors of this revolutionary material, the bezels of these two new models are adorned with purple, green, blue or pink gem-stones that sparkle in the sunlight for a “rainbow” effect.

The ULYSSE NARDIN BLAST is a revolutionary watch with a 45mm case and skeleton “X” dial with complex and geometric forms.

To soften the look, a total of 50 rubies and sapphire baguette gemstones adorn the bezel and the indexes of the RAINBOW edition of the ULYSSE NARDIN BLAST.

The BLAST is powered by the UN-172 automatic flying tourbillon movement with Silicium technology (escapement wheel, anchor & balance spring) enclosed in a black DLC titanium case and sealed with a black ceramic polished and sand-blasted upper case. Boasting a micro-rotor in platinum placed at 12 o’clock, the UN-172 calibre offers 72 hours of power reserve.

Limited to 50 pieces, the ULYSSE NARDIN BLAST RAINBOW watch comes with a waterproof velvet rubber strap or a black alligator strap, together with a black DLC titanium and black ceramic self-deploying buckle. It is water resistant to 50 meters. This timepiece retails at a price of 85’000 CHF.

The new LADY DIVER RAINBOW in black or white is the next generation of the 2019 LADY DIVER but with eye-catching, dazzling decorative touches. Forty stones (ruby, aquamarine, topaz, tsavorite and sapphire) are set on the concave unidirectional bezel of this new watch.

Eleven diamonds serving as indexes increase the scintillating effect of the watch and bring a touch of elegance to this sublime diving watch. Both young and sportive, this 39mm ULYSSE NARDIN LADY DIVER RAINBOW is water resistant to 300 meters.

The UN-816 automatic movement with Silicium technology is the beating heart of each DIVER watch, keeping track of the hours, minutes, seconds, and date.

Both white and black LADY DIVER RAINBOW models come in a limited edition of 300 timepieces each on a white or black structured rubber strap, at a price of 12’900 CHF.
