Strap for Aquaracer Professional 200 Quartz Chronograph Big Date Stainless Steel / Blue

The lug width of this model is 20 millimetres. It is measured by placing a digital calliper between the inner lug attachments of the case, at the point where the strap connects. This dimension is standard across the entire 40mm Aquaracer line and enables broad compatibility with quality aftermarket straps.

The choice depends on intended use: American alligator represents the most refined solution, with natural grain that contrasts splendidly against the brushed steel case. For longevity and natural ageing, vegetable-tanned calf leather is ideal. For frequent water use, textile NATO ensures waterproofness and rapid drying. Medical-grade silicone is perfect for extreme humid environments and swimming pools.

Remove the existing strap using a dedicated tool or small flathead screwdriver to push the spring bar laterally, freeing the strap from the lug. Insert the new strap by aligning the internal hole with the case lug and push the spring bar until you hear the retention click. Verify that the strap is securely fastened on both sides before wearing the watch.

Yes, absolutely. The 20 millimetre lug width is standard and allows the use of quality aftermarket straps. Always verify that the purchased strap is correctly dimensioned in width (20mm) and that the internal hole is compatible with your case's spring bar. Milano Straps offers a wide selection of customisable 20mm straps.

Durability depends on leather quality and intensity of use. A calf leather strap with vegetable tanning, if worn daily, maintains optimal functionality for 3-4 years, while developing a fascinating patina. Alligator, more robust, can reach 5-7 years. Occasional or seasonal use considerably extends durability. Milano Straps offers an 18-month guarantee on straps created by the Casati Milano atelier, with continuous after-sales support.
