Strap for Kleine Da Vinci Yellow Gold / White / Brown Croco

The lug width of the IWC Da Vinci IW3736-01 is 15mm. This measurement is specific to the feminine Da Vinci models from the 1980s and 1990s and is critical to ensure that the strap fits correctly to the tonneau case without play or forcing. It is measured from the inside of the case, between the two lug attachments.

For the Da Vinci IW3736-01 in yellow gold, alligator, shell cordovan or fine-grained calf leather are recommended. Black alligator creates maximum visual contrast; shell cordovan in burgundy or Havana brown tones harmonises with the warm temperature of the case; cognac calf leather offers chromatic cohesion. Rubber and NATO straps are discouraged as they conflict with the refined aesthetics of the timepiece.

Replacing the strap on a Da Vinci IW3736-01 requires a tool called a spring bar tool. Insert the tool between the case and lug on one side, gently push the elastic pin downwards and remove the old strap. Repeat the operation on the other lug. Finally, insert the new strap ensuring that the pin clicks correctly into the case attachments. We recommend entrusting this operation to a professional if you lack experience.

Yes, aftermarket 15mm straps are fully compatible with the Da Vinci IW3736-01, provided that the lug width is actually 15mm and that the strap is made from quality materials. At milanostraps.it you will find selected 15mm straps, customisable and with warranty. A handcrafted alligator or shell cordovan strap can even enhance the original aesthetics of the watch.

A quality leather strap, such as alligator or shell cordovan, has an average lifespan of 3-5 years if worn daily. Wear depends on environmental factors (humidity, sunlight, perspiration), frequency of use and the quality of the leather itself. Straps made with vegetable tanning age elegantly and develop patina. The warranty offered by specialised ateliers such as Casati Milano is generally 18 months against manufacturing defects.
