	Sold from 1965 and named [[Jaeger LeCoultre Polaris\|Polaris]], the model E859 was a diver's watch with internal rotating bezel, for which the watch had a third crown. The watch case was made of stainless steel had an enlarged diameter of 42 mm. This watch was offered in two editions (from 1965 and 1968) with different dials and hands. In both variants, a total of 1714 pieces were produced. The 1965 version had applied metal indices and dauphine hands, while the indices of the 1968 version were printed and featured bâton hands. An additional perforated nickel-plated brass case back with 16 holes improved the sound transmission of the alarm in the 1968 version to compensate for the sound dampening by the wrist and by water.

			The Memovox was developed in 1949, following the development of wrist alarms by other manufacturers which since the first one in 1914 had been beset by problems. The first JLC Memovox was the manual wind cal 489 & was available to the public from 1951. Cal 489 was in production between 1950 & 1958. There are plenty of different case materials, dial furniture and sizes, but they all have the characteristic double crown arrangement. The bottom crown is a traditional winder and time setter. The top crown winds and sets the alarm time.

	From 1955 on, Memovoxes were also available equipped with the caliber K814 which had a date display. Due to the Smoot-Hawley Tariff Act, the Memovox models for the American market were printed and engraved with [[LeCoultre]] instead of Jaeger-LeCoultre until 1980. The calibers for the American market were encased in the USA in watch cases that were locally produced. Accordingly, the dials and case shapes used in the US models differ from European ones. An exception were the case bottoms made of stainless steel, which were always engraved on the inside with LeCoultre on both European and US Memovox watches. The Memovoxes in North America were distributed by the company [[Vacheron Constantin\|Vacheron-Constantin]]-LeCoultre, a subsidiary of [[Longines]]-[[Wittnauer]].
