Strap for Master Collection 44 Retrograde Power Reserve Stainless Steel / Silver-Arabic / Alligator

The Longines Master Collection L2.716.4.78.3 features a lug width of 20 millimetres. This measurement is the essential parameter for strap compatibility: always ensure that any strap you purchase is suitable for this dimension, as different lug widths will not fit correctly into the lugs of the case.

For the Master Collection L2.716.4.78.3, natural leather straps (calfskin or crocodile) offer elegance without adding bulk, whilst technical rubber solutions provide practicality in demanding environments. A dark brown calfskin strap with natural patina enhances the sport-elegant character of the stainless steel case, whilst red crocodile creates a bolder contrast. For those seeking versatility, a woven canvas NATO strap permits rapid changes depending on the occasion.

Strap replacement requires a spring bar tool with a rounded end to compress the spring bars that secure the strap to the lugs. Position the case horizontally, insert the tool into the small lateral notch of the spring bar, compress gently until you hear a click, then withdraw the old strap. Repeat on the second lug. Align the new strap's holes with the spring bars, press with the tool until the second click, and you're done. Avoid excessive force to prevent damage to the case.

A 20mm strap is compatible with any timepiece featuring the same lug width. However, the length of the strap is specific to the watch: the Master Collection L2.716.4.78.3, with its 44-millimetre case, requires a strap proportioned accordingly in length. Before transferring a strap from another watch, verify that the total length is appropriate for your wrist and creates no uneven tension on the case.

A quality leather strap can maintain optimal performance for 3 to 5 years with moderate wear and regular cleaning. Longevity depends on exposure to direct sunlight, humidity, and how the watch is worn. Calfskin straps age beautifully, developing an attractive patina but gradually becoming more delicate, whilst crocodile leather resists longer whilst maintaining structure and lustre. To extend your strap's lifespan, clean regularly with a soft cloth and store in dry environments.
