Created in collaboration with Lufthansa Cargo, the timepiece was inspired by its new high-performance aircraft. A stylised silhouette of the Boeing 777F is placed on the dial.
The watch was tested and certified in accordance with TESTAF, the technical standard for pilot watches, ensuring that it is qualified for professional use at the highest level. The TESTAF quality seal is found on the dial.
The Sinn 857 UTC TESTAF LH Cargo is limited to 777 pieces, each with its limited edition number engraved on the case back.
It has a 43 mm stainless steel case, made with TEGIMENT Technology that ensures it is especially scratch-resistant. The watch also features Ar-Dehumidifying Technology that enhances functional reliability and freedom from fogging. It has a matte black dial, and the numbers, hands and indices are coated with luminescent colour.
The timepiece has sapphire crystal glass, and a captive pilot's bezel with minute ratcheting. Functions include a second time zone on a 24-hour basis, and a date display at 4 o'clock.
This is the second collaboration between Sinn and Lufthansa Cargo, following the limited edition 144 GMT Cargo in 2001.
