Strap for Calatrava 5077 Carousel Red

The lug width of the Calatrava 5077P-062 is exactly 20 millimetres, measured internally between the lugs of the case. This dimension is critical for a mechanically correct fit between case and strap, without play or risk of damage to the lugs.

Alligator remains the most refined and historically coherent choice: its regular and flat grain enhances the richness of the platinum case. Alternatively, vegetable-tanned calf offers chromatic evolution over time and personal patina, whilst shell cordovan guarantees superior wear resistance with lasting amber tones.

The strap is changed by removing the spring bar from the case lugs using a proper spring bar tool. The Calatrava 5077P-062 uses standard 20-millimetre spring bars. It is advisable to entrust this task to a professional to avoid damaging the platinum case, or to use the Casati Milano service, which follows every phase via WhatsApp.

Yes, provided the strap is certified quality and the lug width is exactly 20 millimetres. An aftermarket strap in alligator, vegetable-tanned calf, or shell cordovan, made by specialised craftsmen such as Casati Milano, guarantees aesthetic coherence and durability compatible with the prestige of the timepiece.

A quality leather strap, whether vegetable-tanned or alligator, has a lifespan of 5–8 years of regular use. Durability depends on frequency of use, maintenance, and exposure to humidity. A shell cordovan strap lasts longer, up to 10 years. Casati Milano offers an 18-month warranty on manufacturing defects.
