Family: L789Based on ETA SA 7750
This automatic chronograph with GMT function is manufactured by Longines. Based on the ETA A08.L21—a Longines-branded version of the established Valjoux 7750 architecture—the movement equips the chronograph with a 24-hour GMT hand for dual-time display. Introduced in 2016, it remains in production and appears in Longines' HydroConquest and Avigation collections. The movement is not in-house, relying on the modified ETA base rather than a proprietary Longines caliber.
