About the Polaris family
The Polaris collection was introduced in 2018, inspired by the Memovox Polaris of 1968, a dive watch with an alarm that sounded through the caseback. The modern line has an internal rotating bezel turned by a second crown.
It includes time-and-date models with caliber 899, chronographs with caliber 751H, the Polaris Memovox with an alarm and the Polaris Mariner models, in steel, titanium and pink gold. Dealers identify the function and dial from the reference and check the bracelet or strap.
