Seamaster Ultra Deep Watch 215.30.46.21.03.001

Description

As part of the Five Deeps Expedition in 2019, the Ultra Deep made history when it reached the deepest place on Earth. Following that World Record dive, the game-changing watch has now been adapted for a unique collection available to the public. Tested in real ocean conditions during its development, the design is water-resistant to 6,000 metres (20,000 ft.) and meets the ISO 6425:2018 standard for saturation divers’ watches.

This 45.5 mm model in robust O-MEGASTEEL features a polished black ceramic bezel with its diving scale in Liquidmetal™. Through the protuberant and domed sapphire crystal, the lacquered gradient dial transitions from blue to black, and has been given 18K white gold hands and hour markers, which are all coated with white Super-LumiNova.

The watch is set on an O-MEGASTEEL bracelet with OMEGA’s patented extendable foldover rack-and-pusher with complementary length adjustment and an extra diver extension, while on the caseback's Grade 5 titanium medallion, there is a laser-engraved Sonar emblem with the iconic OMEGA Seahorse at its centre. Inside, the watch is driven by the OMEGA Co-Axial Master Chronometer Calibre 8912.

Master Chronometer Certified

Superior Precision

Twice as precise as any officially certified chronometer

Our Master Chronometer watches are tested and certified twice. First, the movement is Chronometer-certified according to international standard ISO3159, requiring a precision of -4/+6 second per day, following the tests at the Official Swiss Chronometer Control (COSC). Then, the watch head and its movement undergo eight Master Chronometer tests set by the Swiss Federal Institute of Metrology (METAS) with criteria of 0/+5 seconds per day.

Anti-Magnetic

Proprietary anti-magnetic materials

Everyday items such as mobile phones, metal clasps on handbags, laptops, MRI, induction hobs or automatic doors; subject a watch to magnetic fields and can affect its performance. To prevent the risk of permanent deviations of up to several minutes a day we've conceived movements with antimagnetic materials, such as the silicon balance spring, capable of withstanding the highest fields.

Water-resistance

To ensure the integrity of our timepieces at depth, not just some but all watches are fully immersed in water and pressure is applied up to the point of the guaranteed water resistance. By submerging each watch in water we have chosen – yet again - to exceed normal testing standards.

5-Year Warranty

In our quest to raise industry standards and push the boundaries of quality, all OMEGA watches are offered with a full 5-year warranty. This customer promise shows the confidence we have in the excellence of our timepieces, and provides extra trust and assurance when choosing your watch.

Less servicing

Expect fewer visits to the service centre. The Co-Axial escapement is designed to reduce friction inside the movement. As a result, less lubrication is needed and hence less servicing. Compared to non-Co-Axial watches, the intervals between getting your watch serviced will be much longer.

Shock-resistance

During the homologation process, OMEGA watches are tested to the extreme. This phase includes shock examinations, to confirm reliability and to check that its precision is maintained after a severe impact. All OMEGA timepieces are designed to withstand shocks corresponding to a 1-metre drop on a hard wooden floor. For a standard 150g timepiece, this sudden and rapid acceleration is an equivalent force of up to 5,000 G on the watch head.

Professional diving

Certified As A Divers’ Watch For Saturation Diving

To guarantee the Ultra Deep’s ability as a divers’ watch for saturation diving, the timepiece has been tested to meet the ISO 6425:2018 standard. Nine tests are performed and include examinations for Visibility, Magnetic-Resistance, Temperature Cycling, Salt Spray, Shock-Resistance, Water-Resistance, Free-Fall Shock, Resistance of Attachments, and Saturation Diving. METAS certifies that the watch has been tested in conformity with the required criteria.

1 / 6

Grade 5 Titanium

Titanium alloys are light, corrosion-resistant, biochemically inert and able to withstand extreme temperatures. These properties make them particularly appropriate for products in the aircraft, spacecraft and medical sectors. They achieve the perfect balance between solidity, corrosion-resistance and workability. Grade 5 titanium offers a bright grey colour that is close to that of stainless steel, and suits both "brushed" and "polished" finishing.
2 / 6

White Gold

Gold in its pure form (24K) is slightly reddish yellow and very soft. It is usually alloyed with other base metals for a diverse variety of uses. Considered to be the premium standard in watch and jewellery making, 18K gold(with at least 75% pure gold) provides the ultimate balance between purity and usefulness. Traditional 18K white gold is alloyed with palladium-copper and offers an excellent resistance to corrosion, while being highly bio-chemically inert. It provides a beautiful hue that suits wearers even with sensitive skin.
3 / 6

Ceramic

OMEGA has unrivalled expertise in the use of ceramics, dating back more than 10 years. Taking its origin from the Greek word "keramos", ceramic is an inorganic, non-metallic substance obtained by firing at high temperatures. It allows the creation of completely dense watch parts with exceptional mechanical properties. Ceramic is one of the most popular choices for customers when selecting their timepiece, thanks to its appealing colour range and specific properties, such as it being two times lighter than stainless steel, hardwearing, highly scratch-resistant, chemically inert, hypoallergenic, environmentally friendly and non-magnetic.

O-megasteel

O-MEGASTEEL is a new high-performance stainless steel alloy. Through an ingenious Pressure Electro Slag Remelting process, the material obtains a high purity, allowing for a greater polish and incomparable shine. Stripped of its nickel, and boosted with nitrogen and manganese, O-MEGASTEEL also offers a brighter white colour, as well as superior strength and a hardness that is 40% to 50 % higher than conventional steel. As well as being non-ferromagnetic, the unique composition also delivers exceptional resistance to corrosion for a longer-lasting appearance.

Liquidmetal^TM

Since 2010, OMEGA has bonded its ceramics with an alloy called Liquidmetal^TM, which offers new decoration possibilities in a metal grey colour with superior scratch-resistance and enduring stability. Composed of titanium, zirconium and copper, this amorphous alloy is three times as hard as stainless steel. When bonded with ceramic parts, Liquidmetal^TM can be offered in contrasting finishes (brushed or polished), thanks to the difference in hardness between the two materials.

Sapphire Crystal

Protecting the display of this watch is a unique sapphire crystal produced internally by OMEGA, using a specific process called EFG. “Edge-defined Film-fed Growth” creates a crystal that is absolutely defect free, to make the most of sapphire’s unique properties. Sapphire plates are grown, using the EFG process, then cut into discs, machined and polished, to create sapphire crystals of extraordinary strength and clarity, ensuring an unhindered vision of the display at all times.

These properties make them particularly appropriate for products in the aircraft, spacecraft and medical sectors.
