Longines caliber series 99x and Lemania 88xx series
This movement belongs to the Longines 990-family concept that later evolved into the Lemania 88xx series. The 990 architecture is celebrated for combining a remarkably slim profile with technical solutions uncommon in ultra-thin automatics – most notably double barrels coupled in series to support more stable running. After Longines’ integration into what became the Swatch Group era, the design line continued under Lemania, which produced variations of this construction in the 88xx family – making watches like this an important part of the transition from Longines top-spec development into the broader Swatch Group movement ecosystem.
