Strap for Da Vinci Perpetual Red Gold / Black / German

The lug width (misura ansa) of the IWC Da Vinci IW3750-23 is precisely 19.00 millimetres. This measurement must be taken between the two fixing pins at the base of the case using a digital calliper to ensure complete compatibility with aftermarket straps.

For this rose gold 18 carat model, an alligator strap in dark brown represents the most harmonious aesthetic choice. Shell cordovan offers the most exclusive option, developing a natural patina over time. Vegetable-tanned calf leather provides versatility and daily-wear practicality, whilst navy NATO fabric straps retain the chronograph's sporty element.

Strap replacement on the Da Vinci requires a specialised tool: a spring bar removal tool. Position the pin horizontally, apply gentle pressure to extract it from the lug hole, remove the old strap and insert the new one by aligning the pins into the fixing holes. Critical point: never force the pins to avoid case damage. We recommend professional replacement through a specialist centre or at Casati Milano atelier.

Yes, any strap with a certified 19 millimetre lug width is compatible with the Da Vinci IW3750-23, regardless of the watch manufacturer (Omega, Rolex, Tudor, Seiko, etc.). However, the final aesthetic will depend on the visual harmony between the case and chosen strap, so we recommend previewing colour and texture compatibility beforehand.

The longevity of a natural leather strap depends on tanning method and usage pattern. Alligator and shell cordovan can last 5-7 years with proper maintenance and rotation with other straps. Vegetable-tanned calf typically has a lifespan of 3-5 years. Critical factors include prolonged water exposure, perspiration and direct UV light. Casati Milano provides an 18-month warranty on all custom-made leather straps.
