TIMELESS IN THE SKIES, BOLD IN THE SEA
Hanhart FLY NAVY Aerosphere

DESIGNED FOR THE EXTREME
HANHART AND AVIATION
Flying over the sea has always required maximum precision and a keen understanding of the elements. There are few other places where the forces of nature have such a direct effect as on a low flight over the sea on a stormy night, which ends with a landing on a swaying deck. The limited edition FLY NAVY Aerosphere is a reliable and precise watch and the perfect wrist companion for such challenging situations.

SPECIAL ELEMENT
OPTIMUM WEARING COMFORT
With the introduction of a new rubber strap, Hanhart is expanding the wearing options of the FLY NAVY Aerosphere with a particularly functional and stylish variant. The robust bracelet was specially developed for use in water and impresses with its high resistance and ease of care – ideal for daily use as well as for demanding dives. With a high-quality stainless steel folding clasp, even putting on and taking off the watch becomes a small pleasure.
The modern Hanhart logo is discreetly embossed into the rubber material and harmoniously echoes the design of the dial. The FLY NAVY Aerosphere can now be worn with either the new rubber strap in black or blue, the sporty Hook Strapâ„¢ or a classic steel bracelet. In addition to the functional advantage when diving – the strap is easy to clean and at the same time offers the best wearing comfort – it also gives the watches a striking look that perfectly combines sportiness and elegance.
OPTIMAL FOR USE IN WATER
ROTATING BEZEL WITH STANDARD FONT, 30 ATM AND HELIUM VALVE
The FLY NAVY Aerosphere has a water resistance of up to 30 bar (approx. 300 m) so that it is ideally equipped for use on and in the water.
The suitability of the new timepiece for divers is underlined by a helium valve fitted to the case at 10 o'clock. This also creates the indispensable prerequisite for deep divers.
