Strap for Sporting 45mm Chronometer Steel / Black

The lug width of the Ralph Lauren Sporting RLR0220706 is precisely 20 millimetres. This measurement represents the linear distance between the two metal lugs on the case where the strap attaches. To verify the measurement, place a ruler on the inner edge of each lug: the distance should correspond exactly to 20 millimetres. All straps from Milano Straps' 20mm collection will fit perfectly with this timepiece.

The Ralph Lauren Sporting RLR0220706 pairs ideally with vegetable-tanned leather straps (calf leather) that develop patina over time, or alligator leather for a formal and structured finish. For a contemporary sporty approach, NATO straps in cord-dyed cotton offer versatility and radical aesthetic change. Rubber straps with textured finish represent the optimal solution during physical activity. All artisanal materials offered by Milano Straps maintain perfect structural compatibility with the 20mm lug width.

To change the strap on your Ralph Lauren Sporting RLR0220706, you will need a spring bar tool. Locate the small metal lugs on the case and gently lift the strap from the outer side to access the pins. Using the tool, apply gentle pressure inward and downward until the pin retracts. Once retracted, remove the old strap. To install the new 20mm strap, repeat the operation in reverse: insert the pins into the case lugs, ensuring the strap is perfectly aligned before releasing the tool.

Original Ralph Lauren straps comply with the 20mm measurement and feature certified construction quality. Artisanal aftermarket straps from Milano Straps maintain the same structural compatibility (20mm) but offer selected materials and customisable finishes. The main difference lies in the ability to choose specific materials (alligator, vegetable-tanned leather, shell cordovan) and dedicated hardware (gold, silver, titanium) based on personal aesthetic preferences. Both solutions guarantee perfect technical compatibility, provided the lug width is exactly 20 millimetres.

A quality artisanal leather strap, such as those offered by Milano Straps for the 20mm size, has an average lifespan of between 3 and 5 years under normal use conditions. Longevity depends on environmental factors: sun exposure, humidity, frequency of use and maintenance. Vegetable-tanned leather will develop patina more rapidly than alligator, but maintains adequate structural integrity over time. Alligator and shell cordovan exhibit superior resistance to surface scratches. To extend the lifespan, it is recommended to clean the strap periodically with a soft cloth, avoid prolonged water exposure and store it in dry environments away from direct heat sources.
