Swiss watch brand Hublot adds a new King Gold White model to its Oceanographic 4000 line that was created in association with the Oceanographic Museum of Monaco in 2011. This exceptional diver’s watch has a water resistant to the pressure exerted at the record depth of 4,000 metres and also meets 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 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.
As its case is made of King Gold (18K gold with 5% of platinum which gives this special intense red color), the Oceanographic 4000 is still light on the wrist – although its diameter of 48 mm and its volume is substantial.
The 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. The dive time indicator being placed as close as possible to the dial minimises 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 (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 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 also easier to handle and close when using gloves. Note that the design of this buckle is original (because the use of a tongue is rare in the normal Hublot collections) and that its method of attachment to the case is even more so with two small push buttons built into each end of the case to allow the strap to be changed instantly without the use of a screwdriver or any other accessory. The “Town” strap is in white rubber. The “Diver” strap, a blend of white rubber and Nomex™, longer than a standard strap, has been developed to be worn over a diving suit up to 8 mm thick.
