The Da Vinci IW3764-04 (aka: 3764-04, IW376404), seen from the bench

The IWC Da Vinci IW3764-04 is a contemporary evolution of a watchmaking legend from the 1980s, featuring the IWC 89361 automatic movement with integrated flyback chronograph and date function. The tonneau case measures 43.10 mm in stainless steel with water resistance to 60 metres, paired with a 24 mm lug width. This model combines Renaissance-inspired proportions with Swiss precision engineering and is housed within the Da Vinci collection.

Frequently asked questions

What is the lug width of the IWC Da Vinci IW3764-04?

The lug width of the IWC Da Vinci IW3764-04 is 24 millimetres. This measurement is taken between the two spring bar pins where the strap attaches to the case. Verifying this dimension before purchasing an aftermarket strap is essential, as even 1-2mm deviation will compromise fit and wearability.

Which strap material is best suited to the Da Vinci IW3764-04?

For the Da Vinci IW3764-04, we recommend alligator leather in dark tones (black, brown, grey), or vegetable-tanned calf in bordeaux or cognac. Shell cordovan is ideal if you desire a strap that develops a visible patina over time. Avoid overly sports-oriented materials such as NATO or rubber, as these would undermine the mechanical refinement of the chronograph.

How do I change the strap on my IWC Da Vinci?

The Da Vinci's strap is changed by removing the two spring bar pins that pass through the case lugs. You may use a dedicated spring bar tool or a very fine screwdriver. Gently push the pin from one side until it protrudes partially, then extract it fully. Insert the new strap and reinstall the pins. If unsure, entrust the task to an authorised service centre.

Does the IWC Da Vinci IW3764-04 accept compatible aftermarket straps?

Yes, the IWC Da Vinci accepts any strap with a 24mm lug width, regardless of brand. On milanostraps.it you will find a specialised collection of artisanal 24mm straps, customisable with choice of leather, stitching and initials. All our straps are compatible with the IWC spring bar attachment system.

How long does a leather strap last on a watch like the Da Vinci?

A high-quality leather strap (alligator, calf, cordovan) typically lasts 3-5 years with moderate daily wear, or 5-8 years with occasional use. Longevity depends on exposure to perspiration, humidity and frequency of wear. Artisanal straps from Casati Milano carry an 18-month warranty and can be restored or resewn if the structure remains intact.
