King Power 18K Rose Gold Automatic // 731.OX.1170.RX

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. 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 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. 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.
