In association with the Oceanographic Museum of Monaco, Hublot unveils the first diver’s watch able to withstand the record pressure exerted at a depth of 4,000 metres.

Almost all the features of the Oceanographic 4000 are exceptional, in terms of design, development and manufacturing. 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).

Starting with its seal, tested by Hublot in a Roxer tank, submerged and pressurised to the equivalent of 5,000 metres. To ensure the water tightness 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.

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.

The Titanium version ($17,900.00) is limited to 1000 pieces- numbered 01/1000 to 1000/1000. The All Black in carbon fibre ($23,900.00)  is limited to 500 pieces – numbered 01/500 to 500/500.
