Housed in a 40 mm, 12.1 mm-thick 18k rose gold case, the Streamliner Tourbillon Rainbow (Ref. 6804-0401) carries an individual number of 200132584. The cushion-shaped form flows into an integrated 18k rose gold bracelet secured by a push-button folding clasp, and the watch is rated to 12 ATM (120 meters / 400 feet) water resistance. A domed sapphire crystal with anti-reflective coating protects the dial, while a see-through sapphire case back reveals the movement within.
The bezel is set with 60 baguette-cut colored sapphires — 2.90 carats in total — arranged to produce a continuous rainbow effect around the case. Beneath the crystal, the dial is rendered in Vantablack®, a material that absorbs 99.965% of light, creating an extraordinary depth against which the rose gold components and the one-minute flying tourbillon seem to suspend in near-total darkness.
Driving the watch is the HMC 804 manufacture calibre, an automatic movement offering a 72-hour power reserve and displaying hours, minutes, and the one-minute flying tourbillon. This example is presented in unworn condition.
