With its radiant blue dial, this Master Control makes a statement while housing a chronograph, full calendar, and moonphase in a practical 40mm case. A discreet pulsometer scale sits neatly around the dial, echoing the style of classic doctor’s watches. For those who appreciate practical complications in a versatile size, this Master Control hits a sweet spot.

Presents itself in mint condition no signs of wear. The blue sunray-brushed dial catches light beautifully, accented by sunken subdials and a moonphase disc with golden stars. Its high-polished stainless steel case contrasts with brushed sides for balance, while the exhibition back shows off the automatic movement inside. Completing the presentation, the stainless steel bracelet ties the look together with a confident wrist presence.

Functions include hours, minutes, seconds, day, date, month, moonphase, and chronograph. The main pushers operate the chronograph start, stop, and reset, while recessed corrector pushers on the case allow independent adjustments of the date, day, month, and moonphase. It also features luminous hour markers and hands, giving reliable visibility after dark.

Comes as a full set, double-boxed, including the watch pillow, warranty card, user manual, JLC hang tag, pusher tool, and extra blue leather strap.

The Master Control Chronograph proves that complicated watches don’t need oversized cases to shine. Its blue dial, layered with a chronograph, calendar, moonphase, and subtle pulsometer, makes it as functional as it is refined. It is the kind of watch that works equally well at the desk, on the move, or at dinner.
