Jaeger-LeCoultre - Master Control Date & Master Control Calendar with Blue Dials

Jaeger-LeCoultre presented two steel models with blue dials, the Master Control Date Q4018480 and Master Control Calendar Q4148480: Prices from €9,150

One of the pillars of the Jaeger-LeCoultre catalogue, the Master Control collection was launched in 1992 as a demonstration of the Maison’s excellence in watchmaking and marking the beginning of the internal 1000 Hours Control certification of quality standards, a system subsequently incorporated throughout the full range of watches.

The collection is now enriched by two new stainless steel models characterised by deep-blue dials with a sunray-brushed finish, the Master Control Date and Master Control Calendar. Each model is limited to 800 pieces.

The essential codes of the Master Collection are all there: the combination of applied Arabic numerals with faceted dart markers for the hours, faceted dauphine hour and minute hands, and bevelled case lugs that curve towards the strap attachment point. 

The Master Control Date has a diameter of 40 mm with a thickness of 8.78 mm. Readability is enhanced by a minute scale in a subtly contrasting lighter blue, with distinct minute divisions intercut with dot markers in Super-LumiNova.

Featuring the same 40 mm diameter, the Master Control Calendar is only slightly thicker at 10.95 mm. Its jumping date indication adds a vintage touch to this model: a slender date hand extends outwards from the centre of the dial, ending in a red-lacquered Jaeger-LeCoultre logograph that points towards the date on the outer periphery of the dial. 

For optimal reading of the dual-display moon phase and small seconds subdial, the date hand makes a 90° jump between the 15th and 16th day of each month. This ensures that the moon phase and small seconds subdial is never bisected by the date hand.

The snailed small seconds subdial at 6 o'clock is integrated by a the moonphase disc decorated with a star-studded background.

These new models are driven by two Jaeger-LeCoultre in-house automatic movements beating at the frequency of 4 Hz (28,800 vibrations per hours). Visible through transparent sapphire crystals, the Calibre 899AC of the Master Control Date and the Calibre 866 of the Master Control Calendar have 70 hours of power reserve, close to three full days of running autonomy.

Both the Master Control Date and the Master Control Calendar come with matching blue straps in calf leather and fitted with a quick-change mechanism, allowing the wearer to easily switch between a range of straps.

Water resistant to 50 metres / 165 feet, the new Jaeger-LeCoultre Master Control Date ref. Q4018480 and Master Control Calendar ref. Q4148480 have suggested retail prices of Euro 9,150 / US$ 8,700 and Euro 13,800 / US$ 13,150, respectively (Euro prices including VAT, US$ prices before local sales taxes). jaeger-lecoultre.com
