Portugieser IW3714-22— lug 20mm

The lug width (misura ansa) of the Portugieser IW3714-22 is precisely 20 mm. This measurement represents the distance between the two lugs positioned at the extremities of the case and is essential for selecting a compatible strap. All straps designed for this model must be exactly 20 mm wide to ensure a perfect fit without tension on the case or excessive play.

The best strap depends on usage and personal preference. For absolute excellence, we recommend alligator with vegetable tanning: it offers elegant texture, durability exceeding 5-7 years, and a natural patina that evolves over time. For those preferring softness, vegetable-tanned calf leather guarantees artisanal character and superior tactile experience. Shell cordovan remains the purest luxury choice, with density and deep colour, reserved for those who appreciate its initial break-in period.

To change the strap, remove the watch from your wrist and place it on a clean surface. Using a spring bar tool (a small metal implement), gently press inward on one of the lugs to release the internal spring, then extract the pin itself. Repeat on the other side. Insert the new strap by aligning the holes with the lug seats, then reinsert the pins with the spring bar tool until you hear the locking click. If you are uncertain, contact Casati Milano atelier for a professional strap change.

Yes, any strap with a 20 mm lug width is compatible with the Portugieser IW3714-22. High-quality aftermarket straps (alligator, calf, shell cordovan, NATO) maintain the complete aesthetic and functional value of the watch. We recommend choosing a reliable workshop, such as milanostraps.it, which offers artisanal straps with personalisation and warranty, or complete bespoke creation at Casati Milano atelier by appointment.

The lifespan of a natural leather strap depends on the material and usage. Vegetable-tanned alligator and superior quality calf leather guarantee 5-7 years of regular use (daily or multi-weekly wear) before showing significant signs of wear on the closure. Shell cordovan can last even longer, up to 8-10 years, thanks to its structural density. Periodic maintenance (cleaning, conditioning) extends the strap's life. Straps crafted at Casati Milano include an 18-month warranty against manufacturing defects.
