Strap for Constellation Manhattan 25 Quartz Stainless Steel / Silver Silk / Diamond

The lug width of the 131.15.25.60.52.001 model is 16mm. This dimension is determined by the case width and must be measured internally between the two spring bars. A strap with a 16mm attachment will fit perfectly, without play or misalignment with the case lugs.

For this model, alligator in cognac or tobacco brown tones represents the natural choice, creating a chromatic synergy with the black dial and amplifying the visual depth of the overall composition. Alternatively, vegetable-tanned calf offers a patina that evolves over time, while shell cordovan is ideal for those seeking leather with extraordinary constructive properties and a lustre that evokes vintage aesthetics.

To change the strap, you need to use a spring bar tool. Insert the flat end of the tool into the spring hole located at the ends of the case lugs, gently push to compress the pin, then remove the strap. The new 16mm strap should be inserted by aligning the holes at the ends with the pins and ensuring the pin clicks into position with a distinctive click.

All straps with a 16mm lug width are compatible with the 131.15.25.60.52.001. You can choose from alligator, calf, shell cordovan, NATO, rubber or any other material available in the 16mm size, regardless of the aftermarket strap brand. Milanostraps offers a complete collection of customizable 16mm straps.

The lifespan of a leather strap depends on the material and usage. High-quality alligator can last 5-7 years under normal conditions, while shell cordovan can exceed 10 years thanks to its natural density. Vegetable-tanned calf typically lasts 4-6 years. Constant use and humidity exposure reduce longevity, while regular maintenance (gentle cleaning and occasional hydrophobic treatments) extends it considerably.
