Longines Master Collection Watch L2.673.4 Chrono Moon Phase 40mm ALL S.S. Wristwatch

Watch Overview

We are proud to present this refined modern timepiece, a Longines Master Collection Chrono Moon Phase wristwatch, reference L2.673.4.

The chronographs in the Longines Master Collection are all about timeless design and reliable mechanical performance. Each piece is thoughtfully crafted, from the clean, well-balanced dial to the refined movement inside, reflecting Longines’ long-standing tradition of Swiss craftsmanship.

This watch is powered by the original Longines self-winding movement, caliber L678.2, featuring 25 jewels, a chronograph complication with a central chronograph seconds hand. The movement includes a 30-minute chronograph counter with day and month display, a small seconds sub-dial with 24-hour indication, a 12-hour chronograph counter combined with a moon phase display, and a central crescent-tipped hand indicating the date along the outer track. This Swiss-made automatic movement offers precise, dependable performance for everyday wear.

The watch is housed in a 40mm polished stainless steel round case with a smooth bezel and a sapphire exhibition case back, allowing a view of the mechanical movement. It features a pull-push crown, scratch-resistant sapphire crystal, and a water resistance rating of 30 meters (3 bar / 3 ATM).

It features the original black “barleycorn” textured dial, offering excellent depth and contrast. The dial is accented with Roman numerals and elegant silver-tone hands for clear legibility. At 12 o’clock, the day and month display is neatly integrated into the chronograph layout. The 30-minute chronograph counter is positioned at 9 o’clock, the small seconds with 24-hour indication at 3 o’clock, and the 12-hour chronograph counter with moon phase display at 6 o’clock, creating a well-balanced and visually refined composition. The central crescent-tipped date hand completes the dial.

The watch comes fitted with its original stainless steel bracelet. Fully inspected and authenticated by our in-house watchmaker, this Longines runs accurately and is ready to wear and enjoy.
