Longines Master Collection Chronograph Moonphase – Ref. L2.673.4.92.0 (2021)

The Longines Master Collection Chronograph Moonphase ref. L2.673.4.92.0 combines traditional Swiss watchmaking with an impressive range of mechanical complications. Featuring a beautiful sunray blue dial, stainless-steel case and automatic chronograph movement, this sophisticated timepiece offers a complete calendar, moonphase indication and chronograph functionality in an elegant 40 mm design.

Case

The polished stainless-steel case measures 40 mm in diameter, offering balanced proportions despite the watch’s numerous complications.

A scratch-resistant sapphire crystal protects the dial, while the transparent caseback allows a view of the automatic movement.

The case features traditional chronograph pushers and a signed Longines winding crown. Factory water resistance is rated at 30 metres (3 bar).

Dial

The striking sunray blue dial is one of the defining features of this reference, combining a rich blue finish with polished silver-tone hands and applied hour markers.

The dial incorporates several complications arranged in a traditional layout:

• Chronograph: Central chronograph seconds hand with additional counters.
• Complete calendar: Day and month apertures at 12 o’clock, with a pointer date indication.
• Moonphase: Moonphase display integrated into the subsidiary dial at 6 o’clock.
• 24-hour indication: Additional indication incorporated into the calendar layout.

Despite its complexity, the dial maintains the refined aesthetic characteristic of the Longines Master Collection.
