Technical refinements of the
Aquatimer Split Minute Chronograph
Your IWC watch shows you the time in hours, minutes and seconds as well
as the date. With the integral chronograph, you can measure any period
up to 12 hours in seconds, minutes and hours. The duration of a dive can
be read on the bezel inside the case, which can be adjusted in an anti-clock-
wise direction by turning the reset button. You can use the Split Minute
function to mark the start of a decompression stop. The self-winding me-
chanical movement has 30 jewel bearings (synthetic rubies) and a power
reserve of at least 44 hours when fully wound. This watch is shockproof,
antimagnetic, water-resistant to a depth of 120 metres (12 bar) and is pro-
tected by a sapphire glass of hardness grade 9. To ensure that this extra-
ordinary watch continues to perform its tasks in the future, it is absolutely
essential to observe a few important operating notes.
