IWC Aquatimer Automatic Reference 3290 Watch Operating Instructions

The Technical Refinements of the Aquatimer Automatic
Your IWC watch shows you the time in hours, minutes and seconds, together with the date. The dive time is read off on the in ternal rotating bezel, which for safety reasons can only be turned anticlockwise. Your watch is water-resistant 30 bar and protected by a sapphire glass of har dness grade 9 on Mohs\' scale. The mechanical movement with automatic winding has a power reserve of approximately 42 hours when fully wound. To ensure that this extraordinary watch continues to perform faultlessly in the future, it is essential to observe a few important operating instruc-tions.

Marking the Start of A Dive
The triangle on the internal rotating bezel can be aligned with the minute hand by turning the external rotating bezel. The desired point in time (for example the time of entering the water at the start of the dive) can be set in this way. You can read off the elapsed time (for example the duration of the dive) on the internal rotating bezel. For safety reasons, the internal rotating bezel can only be rotated in an anticlockwise direction. The rotating bezel is indexed audibly and per ceptibly in one-minute steps, and it is also legible in the dark thanks to the luminescent markings.
If you are planning to use the watch to time dives, you should be a certified open water diver and have the water­resistance of your watch checked regularly by an IWC service centre.
