The Heritage

The IWC Da Vinci IW3736-02 is a ladies' watch launched in 1985, featuring a distinctive elliptical yellow gold case measuring 29mm in diameter. It houses the Jaeger-LeCoultre caliber 630 automatic movement with hours, minutes, small seconds, date, chronograph, and moonphase functions. The 15mm strap width is precisely calculated to match the case's proportions, ensuring a balanced aesthetic. Water resistance is rated at 30 metres, suitable for daily wear.

FAQ

What is the exact lug width of the IWC Da Vinci IW3736-02?

The lug width of the IWC Da Vinci IW3736-02 is precisely 15 millimetres. This dimension is calculated according to the elliptical case proportions of 29mm diameter. Measuring accurately between the lugs is essential to ensure a perfect fit without lateral play.

Which strap is best suited for the Da Vinci IW3736-02?

For this yellow gold timepiece we recommend alligator in dark brown or cognac tones, which naturally enhances the warmth of the metal. Vegetable-tanned leather represents a noble alternative for those seeking an ageing patina over time. Burgundy calf, conversely, introduces audacious elegance without compromising robustness.

How do I change the strap on the IWC Da Vinci IW3736-02?

Remove the strap by using a spring bar tool to compress the lug pins. Position the watch with the case facing downward, locate the small lateral holes at the lugs and gently compress the inner pin to slide the old strap away. Insert the new strap by aligning its holes to the pins, ensuring the pin clicks securely into position.

Can I use an aftermarket-compatible strap on this model?

Yes, any strap with a 15-millimetre lug width is compatible with the Da Vinci IW3736-02, provided it is constructed from quality materials and finished appropriately to the watch's prestige. Milano Straps offers artisanal leather straps, customisable according to your aesthetic and chromatic preferences.

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

A quality leather strap, crafted with vegetable tanning, typically lasts 3–5 years with daily wear, depending on exposure to moisture, perspiration and sunlight. Milano Straps guarantees 18 months on all artisanal straps, though proper maintenance and storage can extend service life significantly.
