Strap for Da Vinci Perpetual Rattrapante Platinum / Silver / English

The lug width (misura ansa in Italian) of the IWC Da Vinci IW3751-03 is 19 millimetres. This dimension represents the internal distance between the upper and lower attachment points on the case where the strap fastens. It is essential to verify this measurement before purchasing an aftermarket strap to ensure complete compatibility.

Alligator leather is the classic and recommended pairing for the Da Vinci IW3751-03, thanks to its natural geometric texture that dialogues perfectly with the watch's precision engineering. Alternatively, vegetable-tanned calf leather or an FKM rubber strap represent excellent choices respectively for those seeking chromatic evolution over time or sporty daily-wear functionality.

The strap is changed by using a dedicated tool (spring bar removal tool) to gently press the spring bar that holds the strap fixed to the case lug. It is important to work on a soft surface (felt or cloth) to avoid scratches. If you are not experienced, it is advisable to contact a qualified watchmaker or the strap-change service at an authorised dealer.

Yes, provided the strap is manufactured for 19mm lug width. High-quality aftermarket straps, such as those crafted by artisanal leather specialists, are perfectly compatible and often offer greater aesthetic variety compared to official IWC options. Ensure that the strap is produced by experienced craftspeople to guarantee construction quality and durability over time.

The lifespan of a leather strap depends on the material (alligator, calf, shell cordovan) and usage pattern (daily or occasional wear). A quality artisanal alligator strap typically lasts 3-5 years in daily use, whilst a shell cordovan strap can last 5-7 years if maintained regularly. Vegetable-tanned leather develops patina over time but remains functional beyond 5 years with proper care.
