The Da Vinci IW3754-06 (aka: 3754-06, IW375406), seen from the bench

The IWC Da Vinci Perpetual Rattrapante IW3754-06 features a 41.50 mm platinum case paired with caliber 79251, a perpetual calendar movement with rattrapante chronograph, annual indicator, and date-day-month window. This model from the Da Vinci family is designed with 20 mm lugs, a proportion that balances the case diameter without optical excess. Platinum was selected for its superior density, oxidation resistance, and natural patina development over time, reflecting IWC's technical philosophy rather than luxury convention.

Frequently asked questions

What is the lug width of the IWC Da Vinci IW3754-06?

The lug width of the IWC Da Vinci IW3754-06 is 20 millimetres. This dimension is consistent throughout the IWC Da Vinci family and is essential for selecting the correct aftermarket strap. The measurement is taken by measuring the internal space between the two lugs on the watch case.

Which type of strap is most suitable for the IWC Da Vinci IW3754-06 in platinum?

For the Da Vinci IW3754-06 in platinum, we recommend alligator in grey or black tones for monochromatic harmony, or vegetable-tanned calf in cognac for warmer character. Shell cordovan offers particular lustrous opacity, whilst vulcanised rubber represents the technical choice for intense use and variable climate.

How do I change the strap on an IWC Da Vinci IW3754-06?

Strap replacement is performed by removing the spring bars that connect the strap to the case lugs. Use a dedicated tool or fine pin to compress the internal spring of the bar. Extract the bar, remove the old strap, insert the new strap into the lug slots, and reinsert the bar until it locks with an audible click. The operation takes approximately 5–10 minutes with correct tools.

Is an aftermarket strap compatible with the IWC Da Vinci IW3754-06?

Yes, any strap with a 20mm lug width is compatible with the Da Vinci IW3754-06. Artisanal straps from milanostraps.it are constructed to this specific measure and can be personalised in length, initials, and stitching thread colour according to your preferences and wrist size.

How long does a leather strap last on an IWC Da Vinci IW3754-06?

Leather strap durability varies based on material and usage. Alligator and shell cordovan generally offer 3–5 years of daily wear with proper maintenance. Vegetable-tanned calf lasts 2–4 years and develops natural patina. Vulcanised rubber resists 4–7 years in temperate climate. All milanostraps.it straps include an 18-month guarantee against manufacturing defects.
