Strap for Style 28 Stainless Steel / Blue-Diamond / Strap

The choice depends on usage and aesthetic preferences. For formal wear, we recommend alligator in dark brown or black, which emphasises the squared proportions of the case and pairs perfectly with the brushed steel. A textured calf leather in black or burgundy offers versatility and develops a natural patina over time. For sports or summer use, a grey anthracite NATO or fluoroelastomeric rubber strap keeps the wrist cool and preserves the white dial without visual heaviness.

A natural leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with moderate daily use and proper maintenance. Durability depends on factors such as the type of tanning, exposure to moisture, body perspiration and frequency of use. Vegetable tanning resists natural ageing better than industrial tanning, developing a more pleasing patina. To extend strap life, avoid prolonged moisture, dry it after rain, and replace it during winter months with rubber or fabric alternatives. Casati Milano offers an 18-month warranty on artisanal bespoke straps.
