Jaeger-LeCoultre was the first Swiss manufacturer to introduce a wristwatch with mechanical alarm function in 1950. It was a small dress watch measuring merely 35 mm and powered with manual winding caliber. Just 20 years later, the company offered something very different - the Memovox Polaris II. It was engineered for divers, powered with 3rd generation "Speedbeat" automatic caliber, and represented all those inspiring design trends of the 70s! Only 1120 pieces were ever made in all colours: blue (like this one), burgundy, and grey. 

This particular piece is a US-market version with original factory finishing of the case showing moderate traces of use and very well-preserved dial.
