The Ball Engineer Master II Pilot GMT GM3090C-SAJ-BK model combines robustness and precise craftsmanship in a design inspired by pilot's watches. It is an ideal companion not only for air travel but also for everyday use. Thanks to the GMT function, which displays a second time zone via a separate hand, frequent travelers will particularly appreciate this watch.
The case and bracelet are made of high-quality stainless steel, ensuring long life and durability. It is powered by a Swiss automatic Ball RR1201 movement based on ETA 2893, operating at a frequency of 28,800 vibrations per hour, with a GMT function and a transparent sapphire crystal case back that allows a glimpse into the heart of the mechanism. An additional time zone can be tracked thanks to the bidirectional rotating bezel with an aluminum insert. The classic date indicator is located at the three o'clock position.
The watch is designed to withstand shocks of up to 5000 G, which corresponds to a fall from a height of one meter without any damage to the movement.
The dial with excellent readability is covered by a sapphire crystal with an anti-reflective coating, which effectively prevents glare and scratches. Exceptional visibility in dim light and darkness is provided by H3 tritium luminous tubes on the hands and indices, which glow without the need for prior illumination, unlike conventional luminous materials. Water resistance up to 100 meters and a screw-down crown allow the watch to be used for swimming without worries.
