The Royal Oak Offshore DIVER self-winding diving watch is water-resistant to 300 meters and can withstand the pressure of deep-sea diving. It belongs to the exclusive diving watch in the distinguished sports series, and is well received by swimmers and deep-sea exploration. Favored by professionals, it is also the best companion for diving enthusiasts. Even watch lovers who are not engaged in diving will praise its cutting-edge watchmaking technology that is strong, precise, pressure-resistant, shock-proof and magnetic-proof. The new DIVER self-winding diving watch is in the same vein as the Royal Oak offshore series, and is indeed a model in sports watches.

     According to the Swiss International Standard for Watches and Clocks (NIHS), a watch must meet certain specific standards before it can be called a ‘diving watch’. The NIHS 92-11 (ISO 6425) standard stipulates that diving watches must have safety devices to control diving time. In addition, in order to prevent misinterpretation, the device must also have a design to prevent inadvertent rotation. The Royal Oak Offshore DIVER self-winding watch is equipped with a diving chronograph rotating inner ring engraved with detailed minute scales. The unidirectional rotary pawl device that controls the rotating inner ring is connected to the crown at 10 o’clock. The wearer must first unscrew the crown before turning the device. Since this is a rotating inner ring rather than a rotating bezel mounted on the case, the middle layer of the case can also act as a protective barrier. The rotating inner ring is marked with a minute scale, and a very prominent mark is displayed every 5 minutes, which fully meets the requirements of the NIHS 92-11 standard.

    The indications of time, diving inner ring timing, movement movement, etc. must be clearly legible at a distance of 25 cm from the dark sea floor. In order to meet this requirement, Audemars Piguet has redesigned the dial of the Royal Oak Offshore DIVER diving watch: the rod-shaped scale and the minute hand are both stereo faceted and fluorescent treated. Add a fluorescent edge on each side. The fluorescent second hand makes it easy for the wearer to confirm that the watch is functioning properly. The above display is more eye-catching and easy to read against the Royal Black’s unique black ‘Méga Tapisserie’ oversized checkered decoration. In addition, the diving chronograph rotating inner ring is close to the dial, which not only reduces the risk of accidentally changing the diving time, but also makes it easier to read the diving chronograph.

Waterproof and resistant to salt water erosion
    In order to ensure a water-resistant depth of 300 meters, case components such as waterproof pads, bottom covers and mirrors have been adjusted accordingly, mainly to increase thickness. The NIHS 92-11 standard stipulates that the case of a diving watch should be waterproof to a depth of more than 100 meters. Bottom cover screws, middle bolts and Hexagonal screws of the Royal Oak Offshore logo are locked up and down to lock the case tightly, like a submarine’s porthole. In addition, the Royal Oak Offshore DIVER diving watch also successfully passed the salt water immersion test. There is no change in the case, and the movable components can maintain normal functions.

Magnetic, shock and temperature resistance
    The case of the Royal Oak Offshore DIVER Dive Watch ‘Solid Golden Soup’ is equipped with anti-magnetic protection device. The extremely sensitive balance spring can be protected from magnetic fields, vibrations and temperature changes, thereby ensuring the watch’s precise movement. In addition, after testing the watch for temperature changes, no steam condensation was found.

External force bearing characteristics
    Watch connection components should be able to withstand external forces up to 200 N. To this end, Audemars Piguet has increased the size of the standard buckle. The rubber strap and its connecting links also ensure that they can withstand such high external forces.

Pragmatic and simple self-winding watch
    Audemars Piguet’s new diving watch is pragmatic and simple, with no complications beyond the automatic winding function. The watch is equipped with an exclusive Audemars Piguet Cal. 3120 self-winding movement. This movement has been continuously improved, and its reliability is second to none. To ensure accurate travel time, the core components of the movement adopt an adjustable weight balance that vibrates 21,600 times per hour. Eight small weights make the movement adjustment more accurate and stable, and can maintain stability for a long time. Since the horizontal-to-horizontal balance wheel bridge plate is fixed on both sides of the machine plate instead of one side, the shockproof effect is better. The direct-driven central seconds hand prevents chattering when the seconds hand moves.

    In addition, in order to make users feel comfortable, Cal.3120 movement has the function of instant date change and quick adjustment, and has a power reserve of up to 60 hours. When the wearer pulls out the crown to the set time position, the second hand stop device can be activated, and the second hand is immediately stationary, making time adjustment easier.

    However, the finishing touch of Cal.3120 movement is its delicate manufacturing process. The movement components are hand-assembled at the Le Brassus watch factory, ensuring excellent quality throughout the production and precision decoration process. The bridges are carefully chamfered and polished to give a sharp and shiny ridge. The edges of the ruby ​​assembly hole are polished with diamonds, the wheel arms of the gears are chamfered, and the edges and surfaces are polished with diamonds. The grooves of the screws are chamfered. All decorations are done by hand, polished on both sides of the machine with pearl dots, and the bridge is decorated with Geneva waves. The 22K gold plate made of gold bullion is engraved with the words AP and Audemars and Piguet family crests.

Highlight the essence of sports watches
    The superb technical performance and perfect shape design give the Royal Oak Offshore DIVER diving watch a masculine and extraordinary style. The exclusive octagonal case of the Royal Oak offshore has long been synonymous with sports watches. The new watch inherits the stainless steel case of the ancestor of the Royal Oak series, but it is quite ‘blue is better than blue’. As early as 1972, Audemars Piguet introduced the first Royal Oak Royal Sports Watch, boldly introducing stainless steel, which sits on par with the precious K gold. But until 1992, the Royal Oak Offshore watch was launched, with its classic octagonal case extended to the field of extreme sports. The Royal Oak offshore model is first made of rubber, with steel or K gold. Its dial is decorated with a unique ‘Méga Tapisserie’ oversize check pattern. The Royal Oak Offshore DIVER diversifies these classic elements and subtly interprets them. The stainless steel case with a matte finish and a bright finish interlaced is more lively and vivid, with sharp contrast. The crown at 10 o’clock gives the watch its superb technical features. In addition to the above features, it is worth mentioning the classic appearance of the octagonal bezel fixed with eight hexagonal polished screws. The black rubber under the bezel echoes the black rubber on the crown and strap.
