Strap for Constellation Manhattan 28 Quartz Stainless Steel / Grey - Diamond / Diamond

The lug width of the Constellation 131.15.28.60.56.001 is 16mm. This dimension is specific to the 28mm model and determines the compatibility of all replacement straps. To verify it, measure the space between the two lugs with a digital caliper or precision ruler: the value must be 16mm ±0.1mm.

For the Constellation 131.15.28.60.56.001 we recommend authentic alligator for timeless elegance, vegetable-tanned calfskin for everyday aesthetic evolution, or shell cordovan for durability and natural patina. The choice depends on use: dress watch requires alligator or calfskin, while sporty contexts favour rubber or nato military strap.

The Constellation 131.15.28.60.56.001 uses standard straight lugs. Remove the original strap by unscrewing the lugs with a spring bar tool or dedicated instrument, or by sliding the strap laterally if the lugs are removable. Insert the new 16mm strap into the seats, verify case alignment and fasten securely. If you are unsure, consult a qualified watchmaker.

Yes. Online you will find 16mm artisanal straps ready for shipment, customisable in leather (alligator, calfskin, shell cordovan), colour, length size and thread colour. Atelier Casati Milano also offers bespoke creations with direct choice of leathers and 18-month warranty, accessible by appointment.

A quality natural leather strap (alligator or calfskin) typically lasts 3-5 years with daily wear, depending on climate, humidity and maintenance. Vegetable-tanned leather tends to develop patina rather than deteriorate. Shell cordovan, thanks to its density, can exceed 7 years while maintaining structural integrity. Regular maintenance (gentle cleaning and annual conditioning) significantly extends the life of the strap.
