The LeCoultre Polaris Memovox is highly collectible and certainly has a cult following. This watch features a jumbo size 42mm steel case with 2 piece case back designed to amplify the sound of the alarm underwater. The case features 3 oversized crowns with a cross hatch pattern: the top crown sets the alarm, the middle crown turns the inner rotating bezel and the bottom crown sets the time. This piece is powered by an automatic K825 movement with a manually wound alarm function. The watch we are offering here is in excellent condition. The steel case is super strong and the all original dial is a beauty. The black matte dial is all original with gorgeous original lume. This great watch comes with its original LeCoultre box and booklet.
