The 20 mm lug width is engineered for precise wrist fit without lateral bulk, while rose gold enhances contrast with white enamel details and blue-grey guilloché surfaces.

Frequently asked questions

What is the lug width of the Arnold & Son Métiers d'Art 1SJAP.B04A.C113A?

The lug width of the Arnold & Son Métiers d'Art 1SJAP.B04A.C113A is 20 millimetres. This dimension enables a wide selection of compatible artisanal straps, always verified through internal lug measurement with a digital calliper.

Which strap is best suited for the rose gold 1SJAP.B04A.C113A?

For the 44mm rose gold 1SJAP.B04A.C113A, we recommend dark brown alligator, cognac shell cordovan with patinated finish, or burgundy anilina calf leather. These materials create tonal balance with rose gold without competing visually with the Métiers d'Art dial.

How do I change the strap on the 1SJAP.B04A.C113A?

Strap replacement requires a spring bar remover tool to extend the lateral springs of the lug. We recommend entrusting this operation to a professional at Casati Milano, who ensures precise fitting without damaging the rose gold case.

Which aftermarket strap is compatible with this 44mm case?

Any strap with 20mm lug width is theoretically compatible. However, verify the strap thickness (ideally 0.8–1.0mm) to avoid friction on the lug shoulder. Custom fitting at Casati Milano eliminates undesirable play.

What is the lifespan of a leather strap for the 1SJAP.B04A.C113A?

A Horween quality alligator or shell cordovan strap, subject to regular maintenance (cleaning with damp cloth, semi-annual conditioning), guarantees a lifespan of 5–7 years under moderate daily use conditions. Patinated finish tends to enhance aesthetics over time.
