Hublot Oceanographic 4000

In association with the Oceanographic Museum of Monaco, Hublot unveils a diver’s watch able to withstand the pressure exerted at a depth of 4,000 metres. For the first time, the famous Oceanographic Museum of Monaco, with the Institut Océanographique Fondation Albert 1st Prince de Monaco, has agreed to be associated with a watch. The watch will be officially revealed in Monaco today.

“Starting with its seal, tested by Hublot in a Roxer tank, submerged and pressurised 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 case back is screw-down, a sine qua non for reaching such depths. It is made of grade 2 titanium, an extremely strong stainless material.

From the brightness standpoint, the time and elapsed time measured by the flange must be legible from a distance of 25 cm in the dark. To meet this requirement, the dial, the flange and the hands of the Oceanographic 4000 have been optimised to have a larger surface area treated with SuperLuminovaTM, a luminescent material emitting a green colour in the titanium version.

The watch is fitted with two screw-down crowns (a protective measure that helps ensure water resistance by compression of an O-ring seal).The flange crown which sets the dive time is placed at the 2 o’clock position for easy access and more comfortable use.It is unidirectional, again for safety reasons, with a bayonet fitting and protected by an oversized crown guard, for extra safety and easy operation when handling diving equipment. The second crown, for winding and setting the time and date, is positioned at 4 o’clock to avoid obstruction.

Finally, the Oceanographic 4000 has a helium valve, a feature essential to any diving watch capable of descending to great depths.An essential feature when the watch is used in diving chambers, the helium valve allows gases that have infiltrated the watch during the descent to safely escape during the ascent. The valve fitted to the Oceanographic 4000 is made of stainless steel, positioned at 10 o’clock, visible from the left-hand side lug.”

All in all a very impressive timepiece and a welcome addition to the Hublot collection, which sometimes seems a little too focused on their Big Bang model.
