Hublot pays tribute to the elegant Cheval Blanc Randheli, a luxury Maison in the Maldives, with the Hublot Randhelo Oceanographic 4000. This special diver’s watch is available only at Cheval Blanc Randheli and withstands a pressure at the extreme depth of 4000 meters.
In order to be described as a “montre de plongée” (diver’s watch), resistant to the pressure exerted at the record depth of 4,000 metres, the watch had to meet the exacting specifications of the international standards of Swiss Watchmaking (NIHS).
It’s seal was tested by Hublot in a Roxer tank, submerged and pressurized to the equivalent of 5,000 metres. To ensure the watertightness of the watch and to resist this extreme pressure, the synthetic sapphire crystal is 6.5 thick. This is thicker than normal, but is reasonable for this level of resistance. The caseback is screw-down made of grade 2 titanium, an extremely strong stainless material.
Its case is made of titanium, which makes the Oceanographic 4000 light on the wrist. From the brightness standpoint, the time and elapsed time measured by the flange must be legible from a distance of 25 centimeters in the dark. To meet this requirement, the dial, the flange and the hands of the Oceanographic 4000 have been optimized to have a larger surface area treated with SuperLuminova™, a luminescent material emitting a yellow color
The watch’s reading method has been made as safe as possible through the use of an internal rotating flange that is unidirectional and rack-driven, with a dive time indicator.
