IWC Aquatimer Chronograph IW376709 — Exceptional Condition

A particularly well-preserved example of the IWC Aquatimer Chronograph, reference IW376709, presented in excellent overall condition.

This watch was acquired directly from its first owner, who barely wore it and kept it carefully protected in his personal collection rather than using it as an everyday watch. As a result, the watch has been exceptionally well preserved.

One of the most important highlights is the bezel, which is in outstanding condition with no scratches, cracks or visible damage. The bezel is a particularly important component of these Aquatimer models, and examples with a clean, undamaged bezel are increasingly difficult to find.

The original IWC black rubber strap is also in excellent condition, with plenty of life remaining and ready for many years of use.

The watch has also received service and is currently running perfectly.

The watch is registered in the official IWC database, and its authenticity and reference are confirmed. It is 100% original, with no aftermarket parts.

IWC describes the Aquatimer Chronograph as an underwater chronograph designed for scuba diving, with the SafeDive system preventing accidental extension of the dive time. The bezel is operated externally while controlling the internal dive-time scale. (⁠IWC Schaffhausen)

The Aquatimer

The Aquatimer has a particularly important place in IWC’s history. IWC introduced the first Aquatimer in 1967, establishing the company’s dedicated diving-watch family. The original model combined high water resistance with an internal rotating bezel for calculating dive times. (⁠IWC Schaffhausen)

Over the decades, IWC continued developing the concept with increasingly sophisticated diving systems. The SafeDive system used in later Aquatimer generations is designed so that the dive-time bezel can only be rotated counter-clockwise, helping prevent an accidental extension of the planned dive time.

The IW376709 represents the modern interpretation of this philosophy, combining the robust construction of a professional-style diving instrument with a fully functional mechanical chronograph.

Authenticity & Originality

The watch is 100% original and has no aftermarket parts.

The reference and watch are registered in the official IWC database. The watch is offered as an authentic IWC Schaffhausen Aquatimer Chronograph, reference IW376709.

Why This Example Stands Out

The combination of excellent overall condition, an exceptionally clean and undamaged bezel, an excellent original IWC rubber strap, first-owner provenance, limited previous use, recent service and confirmed originality makes this a particularly attractive example for both collectors and enthusiasts.

The IW376709 is already a distinctive and highly capable Aquatimer, but finding one with the bezel and rubber strap preserved to this level makes this particular example especially interesting.
