Strap for Da Vinci Tourbillon Yellow Gold / French

The lug width of the IWC Da Vinci IW3752-04 is 19 millimetres. This dimension represents the historical standard for classic men's watches in this category and ensures perfect visual proportions with the 39 mm case. To verify correct measurement, use a digital calliper positioned on the inner face of the metal bar connecting the fixing pins.

Alligator represents the finest choice from a sartorial perspective: the rectilinear grain naturally dialogues with yellow gold, creating visual harmony without ostentation. An alligator in chocolate brown or bordeaux tones develops patina over time, reflecting the natural ageing of the case. Horizontally-striped calf leather offers a more practical and versatile alternative, maintaining high quality standards with less fragility.

Changing the strap on this model requires extraction of the lug pins (metal bars connecting the strap to the case). Use a specific tool for extraction (spring bar tool), gently pushing from the ends of the bar to compress the internal spring. Once extracted, the old strap separates easily. Insertion of the new strap follows the reverse process: align the holes on the lug seat and reinsert the bar until it clicks into place. We recommend caution to avoid damaging the case lugs.

Yes, any strap with a certified lug width of 19 millimetres is physically compatible. However, aesthetic compatibility depends on the material chosen: alligator, quality calf leather and NATO naturally integrate with the classic style of the Da Vinci. We advise against shiny lacquered leathers or straps with marked textures, which would create stylistic conflict with the sober design intent of the yellow gold case.

A sartorial quality leather strap (alligator, vegetable-tanned calf) typically lasts 3-5 years with daily wear, developing natural patina that increases its aesthetic value. Durability depends on factors such as frequency of wear, moisture exposure, maintenance treatments (periodic nourishment with specific balms) and construction quality. The Casati Milano atelier guarantees 18 months on manufacturing and offers maintenance services to extend the strap's lifespan.
