Men's Aquatimer | Yellow Gold Sport | IWC Watch Collection

0 MATCHES FOUND

The IWC Aquatimer is the brand’s dedicated diving watch. Introduced in the 1960s, just as professional diving and underwater exploration were gaining popularity, it offered a slightly different feature from the diver’s watches of the time: a rotatable bezel located under the glass, to prevent it from being moved accidentally during a dive. Today, the Aquatimer is a cornerstone of the IWC catalog, with a wide range of water-destined watches – from three-handed models to chronographs and perpetual calendars.

While IWC is best known for its pilot’s watches, the brand also makes a capable and stylish line of dive watches – the IWC Aquatimer. Launched in 1967, it was IWC’s answer to the increasing popularity of scuba diving at the time.

Engineered to meet the needs of professional divers, it was made with the robust build and water resistance expected from tool watches, but the IWC Aquatimer had an identity of its own – the rotating bezel for the watch was under the glass and could be operated using a second crown on the side of the case.

Fast forward to today, the IWC Aquatimer is a foundation of the brand’s catalog, offering bold and durable watches for those who love exploring ocean depths. IWC continues to pay homage to their maritime heritage through tributes, with watches that commemorate ‘the father of evolution’, Charles Darwin, and scuba diving pioneer Jacques-Yves Cousteau.

With at least 300m water resistance, precision timing, and captivating designs that offer maximum legibility and contrast, the IWC Aquatimer is perfect for any expedition both below and above the seas.

A BRIEF HISTORY OF THE IWC AQUATIMER COLLECTION

Introduced in 1967, the IWC Aquatimer was the brand’s reaction to the growing popularity of scuba diving and sea exploration.

The first IWC Aquatimer (ref 812 AD) was already water resistant to 200 meters, and featured a unique rotatable bezel. Unlike its contemporaries, its bezel, used for adjusting diving time, is located under the crystal. This prevents it from being moved during the dive and accidentally extending diving time.

The second Aquatimer model (ref 816 AD) was introduced two years later, which featured shaped cases, colorful vignette dials, and an increased water resistance of 300 meters.

In the 1980s, Günter Blümlein stepped in as IWC’s CEO. The engineer and visionary is famous for the renaissance of three leading names in watchmaking – IWC, Jaeger LeCoultre, and A. Lange & Sohne. For IWC, one of his legacies was the partnership with Porsche Design.

This collaboration resulted in a revolutionary new watch, the IWC Aquatimer ref 3500 or Ocean 2000, introduced in 1983. Aside from having a titanium case and a unique, industrial look, it had a record depth of 2000 meters.

The Aquatimer was redesigned again almost three decades later in 2009. This new watch would form the look that we know today – thick chunky cases, scalloped bezels, and an external rotating bezel. Further redesign took place in 2014, which introduced the external/internal rotating bezel that we see today.

Since then, there have been many noteworthy IWC Aquatimer models that pushed the boundaries of what dive watches can do. A few notables ones are:


  • The Aquatimer “Deep Two” IW354702 and the “Deep Three” IW355701 which feature mechanical depth gauges
  • The Aquatimer Perpetual Calendar IW379402 and IW379403 which have digital dates and months
  • The Aquatimer Chronograph “Expedition Charles Darwin” Edition which is the first ever bronze watch created by IWC

True to its heritage, all IWC Aquatimer watches, regardless of depth rating and features, allow the wearer to safely dive beneath the waters. Their stellar design makes them suitable for adventures on land, too.


ABOUT THE IWC AQUATIMER COLLECTION

The IWC Aquatimer collection today features the completely redesigned case. At the core of these models are chunky cases with inset sapphire glass and an external/internal rotating bezel.

Current models are also equipped with the IWC Quick-Change bracelet system, which allows the wearer to switch from a steel bracelet to a rubber strap (and vice versa) without the need for tools.

Here are the sub-collections available in the IWC Aquatimer family of watches:

IWC AQUATIMER AUTOMATIC
The collection’s most basic diving watch. These models feature the external/internal rotating bezel, hands and markers coated with bright luminescence, and a date display at 3 o’clock. All these are set against a black dial for easier reading in low light situations. Inside beats the IWC-manufactured 32111 caliber with 120 hours of power reserve.

Case size: 42mm
Material: Stainless steel with choice of metal or rubber strap

IWC AQUATIMER CHRONOGRAPH
Combines the features of a dive watch and a stopwatch. The external/internal SafeDive bezel system ensures that the inner ring only operates counterclockwise, thus preventing the dive time to be accidentally extended. The caliber 79320, which is based on the legendary Valjoux 7750 movement, powers the stopwatch function of this timepiece.

Case size: 44mm
Material: Stainless steel with choice of metal or rubber strap

IWC AQUATIMER CHRONOGRAPH “GALAPAGOS ISLANDS” EDITION
A special edition stainless steel watch coated with vulcanized rubber. Inspired by the black volcanic rocks of the Galapagos Islands, this watch has an all-black look. On the high-contrast dial, it features the external/internal rotating bezel with SafeDive system and an integrated flyback function. The in-house 89365 caliber movement powers this piece.

Case size: 45mm
Material: Stainless steel with vulcanized rubber-coating case, rubber strap

IWC AQUATIMER CHRONOGRAPH “EXPEDITION CHARLES DARWIN” EDITION
The first bronze watch in IWC’s history, this timepiece is a tribute to ‘the father of evolution’ Charles Darwin and to the expedition of vessels during his time. The choice of bronze is also a homage to his ship, the HMS Beagle, which carried him to his expedition to the Galapagos Islands. It also features functions essential for modern expeditions – the external/internal SafeDive system, rubber-coated pushers, and luminescent markers. On the case back is a portrait of Darwin. Inside beats the IWC-manufactured 89365 movement.

Case size: 44mm
Material: Bronze case, rubber strap

COMMON QUESTIONS ABOUT THE IWC AQUATIMER COLLECTION

The IWC Aquatimer is a collection of professional instruments for divers, underwater explorers and adventurers. Here are some of the most frequently asked questions about the IWC Aquatimer collection.

WHAT IS AN IWC AQUATIMER WATCH?

The IWC Aquatimer is the brand’s flagship line of diver’s watches. Introduced in 1967, its internal rotating bezel set it apart from the tool watches of the era.

Today, IWC Aquatimers feature chunky cases, high-contrast dials, an innovative SafeDive external/internal bezel system, and the Quick-Change bracelet system, all of which aid diving.

ARE IWC AQUATIMER WATCHES WATERPROOF?

IWC Aquatimer watches have a high water-resistance rating starting from 300 meters (30 bar). This level of water resistance is dive watch territory.

There are special IWC Aquatimer watches with greater water resistance. For example, the Aquatimer Automatic 2000 has a 2000-meter (200 bar) water resistance, making it suitable even for deep-sea diving.

HOW OFTEN DO I NEED TO SERVICE MY IWC WATCH?

IWC recommends a complete service every five years to maintain your watch’s performance and accuracy. The intervals between each service will vary depending on how the watch is stored and used.

However, there can be signs that your watch already needs maintenance sooner than later. Read on for Signs It’s Time for Watch Maintenance.
