Strap for Big Crown Pointer Date 40 Stainless Steel - Rose Gold / Silver / Bracelet

The lug width is 20 millimetres. This technical specification is unique to this Big Crown reference and does not represent a widely diffused industrial standard. The lug width must be measured perpendicularly between the two internal contact points of the case, where the lugs protrude. This precision is critical to ensure that the strap seats correctly without excessive slack or pressure against the case.

For the Big Crown, leather straps with vegetable tanning are recommended, such as alligator, English calf, or shell cordovan, which balance the watch's instrumental aesthetic with vintage character. Alternatively, fabric NATO straps or vulcanised rubber offer functional robustness for technical use. The choice depends on context: formal, urban, or outdoor.

The strap is changed by extracting the spring bars that connect the lug to the case. Use a dedicated spring bar tool to gently lift the bar from one side. Once extracted, the strap detaches. Position the new 20mm strap on the lugs, reinsert the spring bar, and verify it seats correctly. The operation takes 2–3 minutes and requires gentleness to avoid scratching the case.

All straps with a 20-millimetre lug width are compatible. Milanostraps offers a specialised selection of artisanal leather, NATO, and rubber straps in this width. It is essential to verify the lug width before purchase, as 20mm is a rare size and 18mm or 22mm straps will not function correctly.

An artisanal-quality leather strap typically lasts 3–5 years with daily wear, depending on tanning method and environmental conditions. Vegetable-tanned leather develops natural patina and ages gracefully; humid or perspiration-prone environments reduce durability. Regular maintenance—drying after moisture exposure, periodic conditioning with natural waxes—significantly extends strap life and accelerates aesthetic patina development.
