OCEANOGRAPHIC 4000 "Jeans"
Hublot and Zegg&Cerlati unveil an exclusive special edition:
The "Oceanographic 4000 Jeans", a diving watch designed to withstand the extreme pressure found at depths of 4,000 metres,
yet boasting a high fashion look featuring denim for a summery feel.

Based on an idea by Tina Zegg and Carlo Cerlati, leading figures in luxury watchmaking based
in Monaco, and backed by Hublot Chairman Jean-Claude Biver and the company's CEO,
Ricardo Guadalupe, this is the first ever ultra-technical diving watch to be adorned with denim.
And we haven't settled for any old denim! The dial and strap are made by an Italian denim
manufacturer who supplies the world's biggest luxury and fashion names. The
"Oceanographic 4000 Jeans" is a special limited edition of just 21 numbered watches
available exclusively from Zegg&Cerlati boutiques, at Place du Casino in Monte-Carlo, Ischgl in
Austria and Samnaun in Switzerland.
The launch of this ultra-technical watch, which combines fashion with the quality craftsmanship
of an Haute Horlogerie timepiece, took place on the 18th February 2013 at the Wellness
Hotel Chasa Montana in Samnaun in the heart of the Swiss Alps (Zegg Hotels & Stores),
and was attended by the German Double Olympic and World skiing champion, Maria Höfl-
Riesch, a Hublot ambassador since 2011. She was joined by Jean-Claude Biver, Chairman
of Hublot, who made the trip, and Tina Zegg and Carlo Cerlati, representing Zegg&Cerlati.
A perfect fusion of technologies developed for the extremes found at depths of 4,000 metres,
this special edition watch, designed to push the boundaries of what is possible while retaining
echoes of high fashion, with its carbon case, dial made from genuine pressed denim wrapped
in epoxy and strap featuring denim stitched onto black rubber, has summer written all over it.
A real instrument with efficiency built into its ergonomics, this watch has been
conceived and designed to test the limits of rationality.
It has taken 18 months of research, development and testing to present the Oceanographic
4000, a watch which can be worn on dives to depths of 4,000 metres, under extreme pressure -
an exceptional technical achievement.
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 watch is water resistant and can withstand this
pressure, the synthetic sapphire crystal is 6.5 mm thick.
This is thicker than normal, but is reasonable for this level of resistance. The case back is
screw-down, essential for reaching such depths. It is made of grade 2 titanium, an extremely
strong stainless material.
The chunky, 48 mm diameter case is made from carbon fibre designed and produced entirely
In terms of brightness, 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
SuperLuminova™, a luminescent material that emits a grey colour.
The display principle 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 is
placed as close as possible to the dial to minimise 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
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 is supplied with two straps: The "City" strap, in denim stitched onto black rubber, and
the "Diver" strap, longer than a standard strap, which has been developed to be worn over a
diving suit up to 8 mm thick. Both feature ardillon buckles. 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.
