The 42.20 mm rose gold case features a 22 mm lug width and is powered by the IWC caliber 18680 visible through a sapphire caseback, regulated by a 1 Hz tourbillon. Water-resistant to 30 meters, the dial is available in satin silver or matte black with applied white gold indices and Roman numerals or batons.

Frequently asked questions

What is the lug width of the IWC Grande Complication IW1868-03?

The lug width (ansa width) of the IWC Grande Complication IW1868-03 is 22 mm. This dimension is specific to this model and determined by the 42.20 mm case diameter. Verifying correct measurement between the two case terminals is essential to ensure perfect fit of any aftermarket strap.

Which strap is most suitable for the IWC Grande Complication IW1868-03 in rose gold?

For a Grande Complication in rose gold, we recommend alligator in vegetable tanning or vitello from the same tanning tradition. Cognac alligator enhances rose gold luminosity with an elegant monochromatic effect, whilst dark brown vitello generates maximum contrast. Cherry shell cordovan is a refined alternative that patinas magnificently over time. Avoid economical straps: the complexity of this watch deserves noble leather.

How do you change the strap on the IWC Grande Complication IW1868-03?

Strap replacement on the Grande Complication IW1868-03 occurs through the case terminals (lugs). With the watch in hand, gently push inward the small release pins positioned on the sides of the lugs, whilst extracting the old strap. Reverse the procedure to insert the new 22 mm strap. If unfamiliar, the Casati Milano atelier provides replacement service with water resistance verification.

Is an aftermarket strap compatible with the IWC Grande Complication IW1868-03?

Yes, any 22 mm strap is technically compatible with the Grande Complication IW1868-03. However, technical compatibility does not guarantee aesthetic harmony: this model requires superior quality straps in noble leather (alligator, vitello vegetable tanning, shell cordovan) to preserve the watch's value and elegance. Milano Straps online catalogues offer curated selections specifically for this segment.

How long does a leather strap last on a watch like the IWC Grande Complication IW1868-03?

A quality leather strap (alligator or vitello with vegetable tanning) on a daily-wear watch like the Grande Complication IW1868-03 lasts approximately 4-6 years, with variables related to climate, frequency of use and personal care. Shell cordovan, a more robust leather, can reach 7-8 years. Natural ageing of leather is part of its charm: over time it acquires patina and character. Casati Milano guarantees its bespoke straps for 18 months.
