The case measures 45 mm x 15.4 mm in thickness and 50.5 mm from lug to lug. It’s a beefy timepiece but extremely light thanks to the titanium use on the case and bracelet. A big benefit of using Titanium on over stainless steel is that the material is hypoallergenic and a lot more scratch resistance.

Under the sapphire crystal is a skeletonized dial which includes applied 18KT rose gold hour indices and 18kt rose gold hands.

The dial also has 2 sub dials for the chronograph and a small seconds sub dial. At the 12 O’clock position is a power reserve indicator but this is for the chronograph since it runs on a separate escapement.

Last but not least is the central seconds hand which is used to measure the 1/100 of a seconds of this high frequency chronograph. Each full revolution of this hand represents just 1 second.

Under the hood is Zenith’s in house movement caliber 9004. This automatic movement is chronometer certified and consist of 2 escapement systems. The first one is for timekeeping and works at 5 hertz and the other escapement is for the incredible high frequency chronograph that works at an astonishing 50 hertz in order to offer 1/100th of a second chronograph function. This escapement is composed of conventional Swiss lever.

Caliber 9004 consists of 293 parts with 53 jewels and power reserve of 50 hours and the chronograph have a power reserve of about 50 minutes. The chronograph is not automatic so it needs to be winded by hand using the crown.

This is a chronograph that has a rich history going all the way back to 1969 and it has now evolved to this mastery piece.
