Master Collection Chronograph Moonphase

The Longines Master Collection Chronograph Moonphase blends classic Swiss watchmaking with a practical complication set, making it a favorite among those seeking both tradition and versatility. Introduced as part of Longines’ flagship Master Collection, it’s celebrated for offering a full calendar and moonphase display at an accessible price point—features usually reserved for far costlier watches. The balanced 40mm case wears comfortably on most wrists, and the elegant guilloché dial with blued hands gives it a refined, dressy presence.

Reference numbers like L2.673.4.78.3 (silver dial, blue hands, brown leather strap) and L2.673.4.78.6 (matching bracelet) are the most commonly sought-after variants. The in-house modified caliber L687 powers the triple calendar, moonphase, and chronograph functions—its column wheel design is a technical highlight at this price. Earlier versions used the L678, so buyers looking for the latest movement should confirm the caliber. Condition, completeness (box, papers, extra links), and dial/strap combinations drive price differences more than age alone.

When evaluating this model, inspect the pushers and crown for smooth operation, as calendar and chronograph mechanisms can be sensitive to misuse. The 30m water resistance means it’s not built for swimming, so pristine examples typically come from careful owners. The Master Collection Moonphase is a strong value proposition for those who appreciate intricate complications without venturing into haute horlogerie territory.
