Jaeger-LeCoultre (JLC) has introduced the Master Control Calendar with a new two-tone and grained sector dial. It features a triple or complete calendar complication with a moon phase display housed in a stainless steel case. It joins the model’s lineup – which includes versions in stainless steel and pink gold.

“The classical triple calendar complication – also known as a complete calendar – shows the day, date, month, and moon-phases, with the days and months in the upper half of the dial, the moon-phase in the lower part and the dates marked around the periphery, indicated by a hand.”

Key Features
Functions and Operations
Hours and minutes. Small seconds. Complete calendar functions of day, date, and month. Moon phase display.
Crown at 3 o’clock to wind and set the time. Corrector at 2 o’clock to set the month. Corrector at 4 o’clock to set the date. Corrector at 8 o’clock to set the moon phase display.
Unlike an annual calendar (does not account for leap years and needs to be adjusted once a year), and a perpetual calendar (accounts for leap years and does not need to be adjusted) – a complete calendar needs to be adjusted five times a year – for months not ending in 31.
Dial

Two-tone and grained sector dial. Faceted dauphine-shaped hour and minute hands and dots on the minute track are coated with Super-LumiNova.
“The two-tone effect of the new grained dial creates a visually compelling and highly legible version of this classical layout, with indications divided into distinct sections defined by alternating shades of light and dark grey. In the lighter-toned centre, the day and month windows are positioned at the top, with black decal indications on white discs. In the lower part of the central area, the moon phase display is contained within the small seconds sub-dial. Set against a blue sky dotted with stars, the polished moon subtly reflects the dark grey hue of the ring displaying the hours. Outside the hour circle, the minutes chapter ring is light grey, while the outermost circle displays the date against a dark grey background. The contrast between the light and dark greys is amplified by the way the grained texture of the dial absorbs and reflects the light differently, according to the shade of grey.”

Our Thoughts

Triple or complete calendar watches are rare. Vacheron Constantin has a handful in its catalogue; part of their Traditionnelle and Fiftysix collections. Jaeger-LeCoultre’s Master Control Calendar with its new dial is an attractive watch – one that evokes vintage vibes. Combined with its contemporary case size and manufacture movement – (JLC is after all The Watchmaker of Watchmakers™) – it is through and through a modern watch. For collectors seeking a vintage-inspired watch at an accessible price (CHF 13,900 is a steal here), this new model promises to be a worthwhile addition to their collections.
