The Polaris 905T471 (aka: Q905T471), seen from the bench
The Jaeger-LeCoultre Polaris 905T471 belongs to the 2018 generation of the Polaris family, evolving the 1968 Memovox Polaris concept toward chronographic complexity while maintaining its sporty identity. The 44mm stainless steel case houses the in-house caliber 752A movement with hours, minutes, world time, and column-wheel chronograph. The 20mm lug width is the native strap size for this reference, with recommended lengths of 115/75mm for average male wrists, adjustable for the 44mm case proportions. Smooth or grained calf leather in navy blue or anthracite complements the satin and polished steel finishes.
