In association with the Oceanographic Museum of Monaco, Hublot unveils the first diver’s watch able to withstand the pressure exerted at a depth of 4,000 meters, or about 13,120 feet. Hublot describes it as a symbolic watch that pushes the limits of what is is rational and possible. The watch required 18 months of research, development and testing to complete. Find pricing and availability date inside.

For the first time, the famous Oceanographic Museum of Monaco, with the Institut Océanographique Fondation Albert 1st Prince de Monaco – names well known in the fields of marine studies, research and conservation – have agreed to be associated with a watch. The Oceanographic 4000 was unveiled on June 6 in the main aquarium in Monaco before HSH Prince Albert II of Monaco and Jean-Claude Biver, CEO of Hublot.

By choosing to support the Oceanographic Museum of Monaco, Hublot is not only honoring the history and heritage of the institution, but has also chosen to give its active support to the study and preservation of the oceans by making a financial contribution to the missions and scientific surveys conducted by the Institute.

The first official meeting of the partnership will be the “DEEP SEA Conference” to be held on October 13 at the Oceanographic Institute of Paris, where Hublot will be the main partner.

Almost all the features of the Oceanographic 4000 are exceptional in terms of design, development and manufacturing. Hublot tested the seal to 5000 meters in a Roxer tank. To ensure the watertightness of the watch and to resist this extreme pressure, the synthetic sapphire crystal is 6.5mm thick. The screw-down case back is made of grade 2 titanium.

The 48mm case is available in titanium, limited to 1000 pieces, or carbon fiber limited to 500 pieces. The elapsed-time reading method has been made as safe as possible, using an internal rotating flange which is unidirectional and rack-driven, with a dive time indicator that is placed as close as possible to the dial to minimize the risk of inadvertently altering the dive time. It also makes the dive time easier to read. In accordance with the standard, the Oceanographic 4000 has a minute scale on which the five-minute periods are clearly highlighted.

The watch is fitted with two screw-down crowns with O-ring seals.The flange crown which sets the dive time is at 2 o’clock for easy access and more comfortable use. It is unidirectional, again for safety reasons, with a bayonet fitting and protected by an oversize 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 which 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 watch comes with two tongue and buckle straps (“Town” & “Diver”). This type of fastening is more secure than a folding clasp for this type of use, and is easier to handle when using gloves. The buckle design is original, as is the method of attachment to the case. Small push buttons are built into each end of the case, allowing the strap to be changed instantly without the use of a screwdriver or other accessory. The “Town” strap is in black rubber. The “Diver” strap, a blend of rubber and nylon and longer than a standard strap and has been developed to be worn over a diving suit up to 8 mm thick.
