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

The lug width is 20 millimetres. This measurement is specific to the IW3714-42 model and is essential for selecting compatible straps. The measurement is taken by calculating the distance between the two lugs (the holes at the extremities of the case where the strap is inserted).

The best strap depends on usage and personal preference. For formal and collector applications, alligator leather with vegetable tanning amplifies the luxury character of the rose gold case. Calf leather is recommended for daily comfort and natural ageing over time. A cotton NATO offers summer versatility and casual wear whilst maintaining the elegant profile of the Portugieser.

The strap is replaced using a small flathead screwdriver or dedicated tool. Insert the tip into the lateral lugs (the small holes at the case extremities), apply gentle downward pressure to extract the connecting pin, then remove the old strap. Insert the new strap by aligning the lugs with the pin and press until it clicks into place.

Yes, provided the strap is compatible with the 20-millimetre lug width. High-quality aftermarket straps in alligator, calf or shell cordovan offer aesthetic variety and often superior maintainability compared to OEM straps. Ensure the strap is constructed with robust lugs and that the clasp is proportionate to the case dimensions.

The lifespan of a leather strap varies based on material, usage and maintenance. Vegetable-tanned alligator can last 5–8 years with regular wear; calf leather 3–5 years; shell cordovan 7–10 years due to material density. Constant exposure to water and perspiration reduces longevity. Periodic maintenance—gentle cleaning and application of specific conditioners—significantly extends the strap's lifespan.
