The Gallet Classics Tribute to Multichron 45 AG0910121B1W3 debuted in 2026 as a part of the brand's bicentennial Classics series. This timepiece features a sleek 38 mm stainless steel casing complemented by a striking black dial, which showcases tone-on-tone chronograph counters. It is outfitted with a beige fabric strap designed with a quick-release mechanism for easy adjustments. Drawing inspiration from the original Multichron 45—known for its accuracy in timing tasks for aviation and motorsports—this contemporary model emphasizes a compact and functional aesthetic. It is equipped with luminous hands and markers for enhanced visibility in dim conditions. With a thickness of around 12.5 mm, this watch is rated for water resistance up to 100 meters and has a sapphire display case back. The mechanical heart of the watch is the manually wound Breitling caliber B09, a certified chronograph movement operating at 28,800 vibrations per hour, providing roughly 70 hours of power reserve.
