Strap for Portuguese Chrono-Automatic Rose Gold / Black / Diamond

The lug width of the IWC Portugieser IW3714-43 is 20mm. This dimension is standard for cases measuring 40.90mm and ensures perfect visual balance between the rose gold case and the wrist. Any strap with a 20mm width will fit correctly into the integrated lugs of the case.

For the Portugieser IW3714-43, alligator leather in chocolate or cognac tones represents the ideal choice due to aesthetic dialogue with rose gold. Alternatively, vegetable-tanned calf leather in dark brown develops magnificent patina over time, whilst shell cordovan in deep red ensures visual density and temporal versatility. Selection depends on use context and personal preference for tactile maintenance.

Strap replacement requires a specific tool (spring bar tool) to disengage the elastic pins from the lugs. Position the watch with lugs facing upwards, gently insert the tool into the lug-strap space, lift the elastic pin and slide the old strap out. Repeat on the opposite lug. Insert the new strap by aligning the holes and re-insert the elastic pins until you hear the locking click.

Yes, any strap with a 20mm lug width is compatible with the Portugieser IW3714-43. High-quality artisanal aftermarket straps guarantee the same reliability and superior aesthetic personalisation compared to original IWC straps. We recommend choosing suppliers who recognise the importance of constructive precision and material quality.

A quality leather strap (alligator, cordovan, vegetable-tanned calf) lasts approximately 3–5 years with regular use and appropriate maintenance. Longevity depends on exposure to moisture, perspiration and frequency of use. Hand-cut leather and artisan stitching tend to develop character over time, increasing perceived value. Recommended: periodic cleaning with soft cloth and occasional conditioning with specific products.
