Strap for Da Vinci Perpetual Rattrapante Platinum / Silver / German

The lug width of the IWC Da Vinci IW3751-01 is 19 millimetres. This measurement is specific to this model and determines the compatibility of aftermarket straps. It is a non-standard size in the commercial market, so it is essential to verify compatibility before purchase.

For a timepiece of this calibre, the ideal strap is alligator leather with vegetable tanning, which enhances the nobility of platinum and develops a fascinating patina over time. Alternatively, shell cordovan offers structure and increasing brilliance, whilst vegetable-tanned calf leather provides softness and discretion. For daily use, rubber or NATO fabric straps in dark colours are also suitable, provided they are 19mm.

Strap replacement is carried out by removing the lug pins using a dedicated tool (spring bar tool). Position the watch on a support bracket, locate the small holes beneath the lugs and push the horizontal pin to extract it completely. Subsequently, insert the new strap by aligning the pins inside the new lugs and push them until they click into place. Avoid forcing, as the platinum lugs are sensitive to excessive pressure.

Yes, an aftermarket 19mm strap is perfectly compatible with the Da Vinci IW3751-01, provided it is constructed to the correct specifications. Quality artisanal 19mm straps, such as those from Casati Milano or available on milanostraps.it, guarantee precise positioning, stability and aesthetic longevity. Ensure that the pins are the correct length (typically 22-24mm) to avoid instability.

The lifespan of a leather strap depends on the material, tanning method and daily use. An alligator strap with vegetable tanning lasts an average of 3-5 years in regular use, whilst shell cordovan can exceed 7-8 years thanks to its robust structure. Vegetable-tanned calf leather has an average lifespan of 2-4 years. Exposure to sweat, moisture and UV rays accelerates ageing. With proper care and periodic treatment with specific creams, longevity is significantly extended.
