Frequently asked questions

What is the lug width of the IWC Grande Complication IW1868-18?

The lug width of the IWC Grande Complication IW1868-18 is 22 millimetres. This measurement is factory-standard and ensures compatibility with high-quality aftermarket straps. To verify correct measurement, place the strap on the case between the lugs and measure the distance between the inner edges of the attachment holes.

Which strap material is most suitable for the Grande Complication IW1868-18?

Alligator leather in vegetable tanning is the primary choice for the Grande Complication IW1868-18, as it dialogues elegantly with the platinum case and develops a natural patina over time. Excellent alternatives include shell cordovan for those seeking compactness and durability, or minimally-grained calf leather for a less formal approach. Avoid synthetic materials that contrast with the dignity of the piece.

How do you change the strap on the Grande Complication IW1868-18?

Strap replacement requires a spring bar tool. Place the watch on a soft surface, insert the bifurcated tip of the tool into the small hole beneath the lug, apply gentle pressure to compress the spring bar, remove the strap and repeat on the opposite side. Install the new strap by reversing the process, ensuring the spring bar is fully seated.

Does the Grande Complication IW1868-18 accept compatible aftermarket straps?

Yes, the Grande Complication IW1868-18 accepts any strap with a 22-millimetre lug width, provided it meets construction quality standards befitting the watch. Verify that the lugs are of appropriate width (minimum 4.5-5 millimetres) and that stitching is executed with fixed stitching using multi-ply thread. Spring bar compatibility is universal, with no adaptations required.

How long does a leather strap last on the IWC Grande Complication IW1868-18?

A high-quality leather strap (alligator or shell cordovan in vegetable tanning) worn daily can last 3-5 years before requiring replacement, depending on usage and climatic conditions. Leather naturally develops creasing at flexion points (spring bars, buckle), a sign not of defect but of noble ageing. An occasionally-worn strap can remain functional for 7-10 years. Casati Milano's guarantee covers construction defects for 18 months.
