IWC Aquatimer Chronograph

Ever since 1967, when the Aquatimer Chronograph saw the light of the day, this model has continued to be one of the references in the timepieces manufacturing industry, especially in the niche category of diving watches. Although the first edition already featured an interior rotating bezel and a 20 bar water resistance level, the contemporary pieces have much evolved in accordance with professional divers’ demands as well as with the advances made by the watch making field itself. While the device’s precision is ensured by the self-winding 79320 caliber it incorporates, a great part of its technical features are oriented towards its use in the diving professional field.

Out of a desire to create a highly functional model, IWC Schaffhausen’s specialists have joined efforts to improve the grip of the rotating bezel so that it can be easily handled while wearing diving gloves. Having the same sport in mind, the readability of the dial has been a constant concern for the Swiss watch makers. Thus, the latest version of the Aquatimer Chronograph (ref. IW376702) includes a backlight system and a 4mm wide sapphire crystal ring bearing a concentrated layer of electroluminescent Superluminova substance on the inner side has been added so that the time measuring device can be used also for night dives. The minutes handle has the same phosphorescent yellow color as the first quarter of the rotating bezel. This is an aesthetic element as well as a professional diving feature as the bright yellow is filtered underwater only when great depths are reached.

Equipped with a quick bracelet change system patented by Cartier, the Aquatimer Chronograph is perfectly suited for underwater use, but also for regular purposes. This practical system unlocks a lever located directly against the horns of the watch, on the inside of the bracelet. Thus, the owner can interchange the two straps (rubber and steel) in a matter of seconds.
