Longines Master Collection Automatic 42 mm Blue Dial Moonphase Date Watch L2.919.4.92.6

Master Collection 42 mm automatic

This Longines Master Collection watch is a 42 mm stainless-steel timepiece driven by the Swiss automatic calibre L899.5. It presents a sunray blue dial with applied indices and a combined moonphase-date sub-dial at six o'clock. The integrated steel bracelet secures with a triple safety folding clasp. It suits buyers seeking a classic luxury dress watch with a useful complication.

72-hour power reserve and 30 m water resistance

The movement beats at 25,200 vibrations per hour and stores approximately 72 hours of energy when fully wound. A scratch-resistant sapphire crystal protects the dial, while the exhibition caseback reveals the finishing of the calibre. Water resistance is rated to 30 metres or 100 feet, which covers splashes and brief immersion but not swimming or diving. Daily wear keeps the mainspring charged through natural wrist motion.

Check wrist size and activity level

The bracelet width is 21 mm and the case thickness is 11.20 mm, so confirm that these proportions fit your wrist and shirt cuffs. The fixed bezel and pull-push crown are straightforward to operate, yet the 30 m rating means the watch should be removed before water sports. Buyers who need a screw-down crown or higher water resistance for regular swimming should consider a different model.
