Frequently asked questions
What is the lug width of the IWC Pilot IW3713-11?
The lug width of the IWC Pilot IW3713-11 is exactly 21mm. This technical specification determines strap compatibility: you must verify that the internal space between the two horizontal lugs of the case is 21mm. Any measurement error results in complete strap incompatibility.
What is the best strap for the IWC Pilot IW3713-11?
For this yellow gold 42mm case, we recommend straps in alligator or shell cordovan leather. Alligator in dark colours (brown, grey) allows the grain of the leather to interact with light reflected from the gold, creating aesthetic coherence. Cordovan offers density that balances the weight of the precious metal.
How do I change the strap on my IWC Pilot IW3713-11?
The strap is removed through the horizontal lugs that hold the lug width in position on the case. Use a proper tool (spring bar tool) to compress the elastic springs located at the ends of the 21mm lug, then extract the old strap. Insert the new strap by aligning the lug holes with the case lugs.
Can I use aftermarket straps compatible with the IW3713-11?
Yes, provided the lug width is exactly 21mm. Verify that the strap is designed for a 42mm case and that the material (alligator, calf, cordovan) is appropriate for the weight of yellow gold. Personalizable artisanal straps allow you to choose leather, colour and customizations.
How long does a leather strap last on the IWC Pilot IW3713-11?
An alligator or calf leather strap of artisanal quality lasts between 5-7 years with daily use. Durability depends on frequency of use, moisture exposure and care. A shell cordovan strap is more resistant and can last 8-10 years. Vegetable tanning develops a patina that increases aesthetic legitimacy, whilst mechanical wear remains the primary factor of deterioration.
