Orologi Calamai Chronograph G50/F

Exclusively designed for pilots and navigators, the Orologi Calamai Chronograph G50/F (Freccia) comes with a robust watch case forged from the steel of an F104 Starfighter jet plane that served in the Italian Air Force. Presently available in four dial versions, this automatic pilot’s chronograph is equipped with the Swiss made Sellita SW510 Top Grade movement.

Founded in 2008 by Francesco Calamai, this small Italian watch company is an official supplier of wristwatches for the Pilots of the Italian Airforce.

This military-grade automatic timepiece takes inspiration from the legendary aviation chronographs. The case of each Orologi Calamai Chronograph G50/F was forged by melting the steel of the G.E. turbine that powered an F-104 of the Italian Air Force.

Indeed, the serial number of the exact turbine utilised is engraved on the caseback. Its 40mm diameter case features alternating brushed and polished finishing. Apart from the time-setting crown at 3 o’ clock, G50/F has an additional crown at 10 o’ clock for operating the inner rotating bezel.

The watch case has been optimised to be as thin as possible by using ultra-modern techniques. The caseback was transformed from a traditional screwed-on model to a more rounded one secured by 4 peripheral screws to accommodate the rotor of the automatic winding mechanism. The crowns and chronograph pushbuttons are specifically designed to be in harmony with the casing and to offer the best grip possible in all conditions.

The dial has been designed to ensure enhanced readability. The applied hour markers are made of metal and highlighted by a generous use of SuperLuminova®. The same technique was used for the numbers and text, with the characters designed to maximise readability in small dimensions.

G50/F has two syringe-shaped luminescent hands for hours and minutes. Tips of the chronograph hands (central 60 seconds, 30-minutes and 12-hour) are highlighted with red color. The watch displays the date at 4.30H.

Orologi Calamai Chronograph G50 F

The Sellita 510 is an evolution of the self-winding calibre SW500, with the main difference being in the arrangement of the registers, evolving from a 12-3-6 layout to the classic 3-6-9. This chronograph watch houses a “coulisse” escapement, which is less elaborate than the “column shaft” mechanism but offers great advantages in terms of robustness, simplicity and reliability.

The Orologi Calamai Chronograph G50/F is available in Black “sablé”, Blu Soleil, Dark Brown and Anthracite dial versions.
