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.

Questions about this item
How do I fit the blue leather strap to the 42 mm case without damaging the 21 mm lug holes?
Align the spring bars with the lug holes, compress each bar fully with a spring-bar tool, and seat it evenly; forcing one side first bends the 21 mm leather tabs and can crack the lug shoulders.
What part of the watch will need service first and when?
The Swiss automatic caliber L897.2 should receive a full movement service every three to five years; the leather strap will show wear sooner and should be replaced when the underside cracks or stiffens.
How long will the movement run if I stop wearing the watch for a few days?
The caliber L897.2 stores up to 72 hours of power reserve at 25,200 vibrations per hour, so the watch keeps running for about three full days off the wrist.
