About the Jaeger-LeCoultre Master Control

The 2020 generation is what the library holds: the Master Control Date on the 899AC, the Calendar with its triple calendar and moon on the 866AA, the Memovox alarm on the 956AA, the Geographic with its second time zone on the 939AA, and the Chronograph Calendar on the 759, which combines a chronograph with a full calendar and is the collection's most common movement at 12 references. The earlier 899 and 899/1 account for 6.

The 40 mm case accounts for 29 references and the 39 mm of the earlier Date for 6. Steel is the material of 27 cases and pink gold of 8. Silver dials lead at 26, with blue on 5 and black on 4. 12 references are chronographs. Water resistance is 50 m, and every reference has a display back. 5 are limited editions.

The Master collection holds the earlier Master models and the tourbillons, the Master Ultra Thin the slim version, and the Polaris the sports line that shares the Memovox alarm.
