Strap for Da Vinci Perpetual Rattrapante Platinum / Silver / English

The lug width of the IWC Da Vinci IW3751-04 is precisely 19mm. This measurement represents the space between the two metal lugs on the case where the strap attaches. It is essential to verify that your strap has terminals of exactly 19mm width to avoid lateral play or stress on the lugs.

For a 39mm platinum case, we recommend straps in black or dark brown alligator with vegetable tanning. Alligator offers discreet texture and longevity; vegetable tanning allows natural patina development that enhances contrast with the immutable platinum. Polished calf leather is not recommended, as it visually competes with the metal case.

Strap replacement requires a quality spring bar tool: insert the tip into the groove of the spring bar located beneath the lug, apply downward and inward pressure, then remove the worn strap. Insert the new bar (if required) into the designated holes of the new strap, then reposition the entire assembly under the opposite lug until you hear a click.

Yes, provided the terminals are rectangular and free of excessive bevels, and the width is strictly 19mm. Straps with traditional leather loop or deployant buckle are both compatible. Always verify that the strap is not excessively rigid to prevent stress on the lug bars during changes.

A high-quality leather strap (alligator, calf, shell cordovan) offers 3-4 years of daily use before showing signs of structural failure. Factors such as humidity, frequency of use, and tanning method significantly influence longevity. Vegetable-tanned leather tends to age more rapidly but in a noble manner; chrome-tanned leathers offer greater resistance.
