JAEGER‑LECOULTRE MASTER CONTROL CHRONOGRAPH CALENDAR REF. Q4138180 CALIBRE 759

The Master Control Chronograph Calendar follows in the footsteps of the round watches so popular in the 1950s. Set in a case with a double brushed and polished finish, the two-tone dial offers incredible legibility for its functions (hours, minutes, small seconds), as well as its complications, notably the chronograph with its pulsometric scale and 30-minute counter. Visible under the sapphire crystal case-back, the in-house calibre 759 promises 65 hours of power reserve. Offered with an assortment of interchangeable straps - one in steel links, the other in blue leather - the Master Control Chronograph Calendar can change its look in an instant, while remaining resolutely in tune with the times.
