Strap for Da Vinci Tourbillon Leonardo Yellow Gold / English

The IWC Da Vinci IW3752-15 features a 19-millimetre lug width, specifically proportioned for the 39mm case diameter. Verify this measurement by positioning a digital caliper perpendicular to the internal profile of the lugs. On vintage gold examples, check twice to exclude wear-related variations.

Natural alligator leather with irregular grain is ideal, as its non-uniform texture creates visual dialogue with yellow gold and develops natural patina over time. Vegetable-tanned calf offers a classical alternative with understated elegance. Shell Cordovan excels if you prefer intrinsic lustre without competing with the case's warmth.

Use a dedicated spring bar tool to push the lug spring's shoulder towards the case centre. Remove the old strap, gently insert the spring into the new strap's seat, and reinsert the spring into the case lugs. Verify that the strap is centred and does not generate friction against the case.

Yes. A quality aftermarket strap with 19mm lug width is entirely compatible with the Da Vinci IW3752-15. Verify precise lug width and ensure leather quality matches watchmaking standards (alligator, calf, shell cordovan). Casati Milano atelier provides bespoke straps custom-made for this model.

A quality watchmaking leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts 3-5 years with daily wear, depending on exposure to perspiration and humidity. Leather tends to dry and lose elasticity. Well-constructed vegetable-tanned calf requires less maintenance; alligator develops patina faster. Preventive replacement every 2-3 years preserves your watch's aesthetic integrity.
