Frequently asked questions

What is the correct lug width for the IWC Da Vinci IW3736-09?

The IWC Da Vinci IW3736-09 features a lug width of 15mm. This is the distance between the pins that attach the strap to the case lugs. Verifying this measurement is essential before ordering an aftermarket strap to ensure perfect compatibility and secure wear.

What is the best strap material for a Da Vinci in yellow gold?

For an IWC Da Vinci IW3736-09 in yellow gold, vegetable-tanned alligator represents the most refined choice: it develops a patina over time that complements the refinement of aged gold. Alternatively, vegetable-tanned calf or Shell Cordovan guarantee elegance and longevity, with distinct tactile and chromatic characteristics that adapt to different wearing styles.

How do I change the strap on the IWC Da Vinci IW3736-09?

Changing the strap on a watch with a 15mm lug width requires specific tools: a suitable springbar screwdriver and a springbar removal tool. Position the screwdriver in the small longitudinal slot of the spring pin, apply gentle pressure until the latch releases, and remove the old strap. Insert the lug of the new strap and reseat the spring pin. If you prefer, Casati Milano offers a strap-changing service with personalized consultation.

Can I use an aftermarket strap on a 29mm watch with 15mm lug width?

Yes, provided the strap is specifically constructed for a 15mm lug width. Milano Straps supplies a curated collection of compatible straps for this measurement, crafted by artisans specializing in fine leather and superior quality fabrics. Compatibility ensures both correct aesthetics and functional security.

How long does a leather strap last on a daily-wear watch?

A quality leather strap, with vegetable tanning and conscientious craftsmanship, typically lasts 3-5 years with moderate daily use. Durability depends on ambient humidity, frequency of changes, and care. Casati Milano guarantees 18 months on bespoke straps, with the possibility of regeneration or leather replacement over time, while maintaining the same tailored shape.
