Longines Master Collection L2.920.4.92.0 42 mm Blue Dial Leather Strap Watch

Longines Master Collection Annual Calendar

The Longines Master Collection L2.920.4.92.0 is a 42 mm stainless steel watch with a blue sunray dial and leather strap. It features a Swiss automatic mechanical annual calendar movement displaying date and month at 3 o'clock. The transparent caseback reveals the L897.2 calibre beating at 25,200 vibrations per hour. This luxury timepiece suits adults seeking a refined dress watch with practical calendar complications.

30 m water resistance and 72 hour power reserve

The watch offers water resistance to 30 metres or 100 feet suitable for splashes and brief immersion. Scratch-resistant sapphire crystal protects the dial. The automatic movement generates up to 72 hours of power reserve when fully wound. No battery is required as the rotor winds the mainspring through natural wrist motion during daily wear.

21 mm leather strap with triple folding clasp

A blue leather strap 21 mm wide secures with a triple safety folding clasp and push-piece opening mechanism. The 10.50 mm case thickness allows the watch to slide under shirt cuffs easily. Fixed bezel and pull-push crown complete the 42 mm round case profile. Buyers needing higher water resistance for swimming or diving should consider other models.
