Bremont was commissioned to produce a unique world timer chronometer for the military C-17 Globemaster crew. The ALT1-WTBK
watch features intricate details inspired by the C-17, including the etched globe and the internally rotating bi-directional bezel which allows the user to work out global time zones using the International Civil Aviation Organization (ICAO) airfield identifiers, each of which represents a C-17 landing location in each of the 24 time zones. This chronometer is powered by a calibre 13 BE-54AE automatic movement constructed with 25 jewels, beating at 28,800 VpH with a power reserve of 42 hours.
