Overview

The Longines Master Collection Chronograph Moonphase (ref. L2.673.4.78.3) brings together a chronograph, triple calendar, and moon-phase display within a 40 mm stainless steel case. Its silver barleycorn dial is a deliberate nod to the decorated dials of mid-twentieth-century Swiss watchmaking. Calibre L678 powers the ensemble, delivering the layered functionality expected of a serious dress complication.

History

Longines introduced the Master Collection in the early 2000s as a vehicle for reviving the brand's heritage of elegant, complication-rich pocket and wrist watches. The L2.673.4.78.3 has remained a consistent presence in the line since its introduction around 2005, demonstrating the collection's long-running appeal among collectors who favour traditional grand-complication aesthetics at an accessible tier of Swiss watchmaking. The reference sits alongside simpler Master Collection variants, anchoring the upper end of the family with its stacked calendar and lunar indications.

Notable points

The silver barleycorn dial features a fine guilloché-style texture that references classical Swiss and European decorative dial traditions.
Calibre L678 is an integrated movement offering simultaneous chronograph, triple-calendar (day, date, month), and moon-phase functions.
The 40 mm stainless steel case occupies a versatile size suited to both formal and smart-casual wear.
The moon-phase display is set at the lower portion of the dial, complementing the symmetrical layout of the calendar subdials.
As part of the long-running Master Collection, the reference reflects Longines' sustained commitment to complication watchmaking within the Swatch Group portfolio.
