Description
spring drive chronograph with gmt function
With a discreet and refined profile, this Spring Drive Chronograph with caliber 9R86 is highly functional and displays the time and elapsed time with exceptional accuracy.
The chronograph measures elapsed time up to 12 hours while the seconds hand glides continuously, silently and smoothly over the dial. The GMT hand allows the time in a second time zone to be read accurately and the hour hand can be set to a new time zone without compromising the accuracy of the timekeeping.
The case is made of high-intensity titanium, a material that is 30% lighter than steel but also more resistant to scratches and corrosion.
A chronograph with a strong impression of robustness.
