Strap for Da Vinci Perpetual Stainless Steel / White / German / Bracelet

The lug width of the IWC Da Vinci IW3750-19 is 19 millimetres. This dimension represents the internal distance between the two attachment pins of the case. To verify correctly, use a digital calliper by measuring internally between the pins, without considering the external nuts. Accurate measurement is essential to ensure strap compatibility.

For the Da Vinci IW3750-19, we recommend alligator straps in black with contrasting stitching, vegetable-tanned leather in dark brown tones, or FKM rubber for more sporty use. Alligator with fine, uniform grain enhances the formal character of the watch, whilst leather offers a natural patina that develops over time, creating a pleasant contrast with the polished stainless steel case.

To change the strap, you need a small spring bar tool. Position the watch on a soft surface with the case facing downwards. Insert the spring bar tool into the small hole beneath the first pin, push gently inward to compress the spring, and extract the pin. Repeat on the opposite side. Ensure the pins are identified as 19 millimetres before inserting them into the new strap.

Yes, any strap with a 19-millimetre lug width is compatible with the Da Vinci IW3750-19. High-quality aftermarket straps, such as those in artisanal alligator or vegetable-tanned leather, do not damage the case whatsoever and often improve the overall aesthetic of the watch compared to factory straps.

A high-quality leather strap (alligator or vegetable-tanned calf) typically lasts 3-5 years with daily wear and proper maintenance. Factors affecting longevity include: sun exposure, frequent water contact, ambient humidity, and frequency of rotation between different straps. A strap used occasionally may last 7-10 years. FKM rubber has a slightly shorter lifespan, around 2-3 years with intensive use.
