Strap for Portuguese Automatic Tribeca Film Festival 2013

The lug width of the IWC Portugieser IW5001-26 is 22mm. This width is measured between the lugs of the case and represents IWC's construction standard for this model. To verify the measurement correctly, position a ruler perpendicularly to the watch's axis, from the inner shoulder of the upper lug to the lower one.

Mississippi alligator is the most noble material for the Portugieser IW5001-26, thanks to its regular grain and natural luminosity that dialogues perfectly with the stainless steel case. Shell cordovan represents an elegant alternative with a patina that evolves over time. For more dynamic contexts, a tactical NATO strap or high-modulus rubber maintains the watch's aesthetic dignity.

To change the strap, use a spring bar tool or a small flat-head screwdriver. Insert the tool under the spring bar to push upwards and release it from the case lug. Repeat the operation from the other side. Install the new strap by clicking the spring bar back into place, ensuring it is secure before wearing the watch.

Yes, any strap with a 22mm lug width is compatible with the IWC Portugieser IW5001-26. However, we recommend choosing straps made by specialised manufacturers that guarantee finishes and construction quality consistent with the watch's calibre. Dimensional compatibility does not preclude the importance of aesthetic and structural quality.

The lifespan of a leather strap depends on the tanning method and frequency of use. Quality alligator or shell cordovan can last 3-5 years with daily wear, whilst vegetable-tanned calf leather typically wears out in 2-3 years. Factors such as humidity, sun exposure and frequency of use directly influence longevity. The Casati Milano atelier provides an 18-month warranty on made-to-measure straps.
