Strap for Prestige Gold 19.5 Quartz

The lug width is 16 millimetres. This specific measurement identifies the space between the lateral lugs of the case where the strap must fit. To verify compatibility, measure the internal distance between the lugs with a digital calliper or flexible ruler, ensuring the strap is constructed precisely for this width.

For this yellow gold model with a 19.5mm diameter, alligator remains the most coherent choice: the squamated texture pairs naturally with the geometric sobriety of the case. Jet black alligator creates formal contrast; cognac or dark brown introduce warmth. Valid alternatives include vegetable-tanned leather, which patinas alongside the gold, or shell cordovan for exceptional durability. For everyday wear without formality, smooth calf or butyl rubber offer comfort and versatility.

Use a specialised tool (spring bar tool) to remove the elastic pins (spring bars) that secure the strap to the lugs. Position the tool in the lower slot of the pin and extract with gentle downward pressure. Once free, slide the strap away from the case. For mounting a new strap, align the pin with the lugs and push until it clicks into position. Ensure the strap is constructed for 16mm to guarantee correct fit without friction against the case.

A high-quality artisanal leather strap, crafted with noble materials such as alligator, shell cordovan, or vegetable-tanned leather, typically lasts 5–10 years of daily wear, depending on ambient humidity and maintenance. Vegetable-tanned leather and shell cordovan tend to offer superior longevity due to their more resilient fibrous structure. A butyl rubber strap lasts considerably longer, up to 15–20 years. Regular maintenance (cleaning and occasional conditioning) significantly extends the material's useful life.
