The Master Collection represents Longines at its most classically elegant, and the Moonphase variant adds genuine complication to that traditional silhouette. The 40mm stainless steel case houses a black dial with a fine textured finish, framed by applied white Roman numerals and dauphine hands. A moonphase and date sub-dial sits at 6 o'clock, displaying the lunar cycle against a starlit blue disc alongside a running date scale — a classic complication rendered with real restraint. It's presented on a stainless steel bracelet with Longines' triple safety folding clasp and push-piece release mechanism.

Powering the watch is the Longines Caliber L899, a self-winding mechanical movement beating at 25,200vph (3.5Hz), with 21 jewels and an impressive 72-hour power reserve — well ahead of most watches at this price point.

This example is a 2021 production. It presents beautifully on the wrist, in very good overall condition. Under close inspection, minor handling marks are visible on the case and bracelet; the crystal, dial, and hands remain flawless. It comes complete with its original box and warranty papers, and includes an additional used leather strap with Longines clasp.

For the collector drawn to old-world watchmaking elegance backed by a genuinely long power reserve, the Master Collection Moonphase offers a complication-rich alternative to the usual three-hand dress watch, at a fraction of what comparable moonphase pieces command from the major maisons.
