Jaeger-LeCoultre Memovox Polaris
More actions
The Jaeger-LeCoultre Memovox Polaris is the diving version of the maker's alarm watch, pictured here as the 1968 reference E859. A mechanical alarm is a hammer striking the case, and a case sealed well enough to dive is also sealed well enough to be silent, so Jaeger-LeCoultre built the Polaris with a triple caseback: an inner back the hammer strikes, a middle resonance chamber, and an outer back pierced with sixteen holes to let the sound out, with the whole assembly still rated for diving. An internal rotating bezel driven by a second crown times the dive; the automatic calibre 825 runs it. (Jaeger-LeCoultre)
Production and revival
Roughly 1,714 were made. Jaeger-LeCoultre revived the Polaris name as a full collection in 2018. The modern line shares the name and the dial grammar rather than the alarm architecture.
