Strap for 1815 35.9 White Gold Black

The lug width of the 206.029 is 19 millimetres. This dimension is specific to classical models of medium proportions and ensures aesthetic balance between the 35.90 mm case and the strap. To verify accurately, use a digital calliper positioned perpendicularly to the caseback at the strap attachment point.

To maintain the classical German aesthetic of the 206.029, alligator in dark brown tones is the natural choice: geometric grain texture and patina that evolves over time. Equally premium alternatives are shell cordovan (superior durability, enhanced reflectivity) and vegetable-tanned calf (daily versatility, natural ageing). A white gold deployante clasp, if available, further amplifies the overall refinement.

On timepieces of the 206.029's value, strap replacement should be entrusted to a qualified watchmaker or directly to Casati Milano. Using unprofessional tools risks scratching the white gold case or damaging the lugs. A professional watchmaker will use an optical bench to ensure precise lug alignment and proper clasp or deployante tension.

Any strap with a 19 millimetre lug width is compatible with the 206.029. Milanostraps.it stocks a collection of bespoke leather straps in 19mm, crafted from alligator, shell cordovan, calf and other premium materials. Each strap can be customised according to colour and finish preferences. Casati Milano also offers an atelier service in Milan for personal leather selection and production oversight.

Lifespan depends on material quality and wearing frequency. Premium alligator resists 4–6 years with daily wear. Shell cordovan, owing to superior density, can reach 8–10 years. Vegetable-tanned calf requires slightly greater maintenance (protection from moisture and soiling) but offers 5–7 years of useful life. In all cases, initial water-resistance treatment and periodic maintenance (cleaning, conditioning) significantly extend longevity.
