Rare Sector Dial: cal906 JLC Chronometre Royal

Jaeger LeCoultre Master Mariner: Chronometre Royal, cal906: Antimagnetic & Seconds-Hack

CHF 9,000

WHY WE LOVE IT: Because it is a pioneering luxury steel-sportswatch (1973) that was made in less pieces than any of the more popular competitors (AP Royal Oak, PP Nautilus, IWC Ing) -- a trendsetter and a sleeper.

Here in the amazing slate-grey dial variant -- it was made in white / light grey, blue and slate-grey -- with original tritium dots next to the applied indexes. You can see the patinae on the parts where the radiation influenced the grey-blue dial around the tritium dots.

The very sophisticated cal906 is a early '70s counter-attack to electronic movements (quartz & tuning-fork) by JLC and it comes not only with a special date-setting mechanism but is chronometer-graded, has a hacking-second, efficient automatic-winding and is antimagnetic. However, it was fighting an already lost battle -- and was thus made just in a few examples. By far less than the AP5402 or Patek3700.
