Special Editions WCF20TJSARB21AA— lug 20mm

The lug width of the WCF20TJSARB21AA is 20mm. This measurement represents the distance between the two internal attachment points of the case where the strap is secured. It is essential to verify this measurement with a digital calliper before ordering a new strap.

For this rose gold timepiece with tourbillon movement, we recommend alligator leather in cognac tones or vegetable-tanned calf that develops natural patina over time. Both materials evolve aesthetically alongside the case, creating authentic material harmony throughout the years.

Remove the watch from your wrist and place it on a soft surface. Use a spring bar tool to gently unhook the spring bars from the lugs. Insert the new strap, aligning it with the apertures, and reattach the spring bars until you feel the securing click. Never force to avoid damage to the case lugs.

Yes, provided the lug width is exactly 20mm. Milano Straps produces artisanal 20mm straps in multiple materials and finishes. We recommend selecting certified European productions that guarantee mechanical compatibility and material nobility consistent with your watch's value.

A quality leather strap, especially vegetable-tanned, has a useful life of 5-8 years with moderate daily wear. Longevity depends on sun exposure, humidity, and wear frequency. The rose gold WCF20TJSARB21AA will age gracefully for decades, so plan strap replacement as conscious ordinary maintenance.
