Strap for Portuguese Chrono-Automatic Stainless Steel / Zürich

The lug width (also called ansa width) for the Portugieser IW3714-93 is precisely 20 mm. This measurement represents the distance between the two metal lugs on the case where the strap is fixed. To verify, measure the space between the lugs directly with a calliper, parallel to the dial. This exact measurement ensures perfect fit and proper strap attachment.

We recommend three principal options for this model. Alligator leather, with its regular dermic structure and natural grain, represents the most sophisticated choice and communicates understated elegance. Vegetable-tanned calf develops a unique patina over time and offers a more intimate feel. Shell cordovan, rare and dense, provides deep lustre and is highly valued by collectors. Your choice should reflect your intended wear context and how much you wish the watch to evolve personally.

The Portugieser IW3714-93 uses a spring bar or pin fastening system, which may vary by production year. To change the strap: position the watch with the strap facing downward, locate the small lever or pin within the lug, use a proper spring bar tool to compress the mechanism and slide the pin out of the cavity. Insert the new strap's pin using the same procedure. If uncertain, consult a qualified watchmaker.

Yes, absolutely. Any strap with a 20 mm lug width is mechanically compatible. Aesthetic compatibility depends on your personal preference: colour, material, and texture must visually dialogue with the brushed steel case and dial design. We strongly recommend selecting premium leather (alligator, calf, shell cordovan) to ensure longevity and comfort over extended periods.

A high-quality natural leather strap, with ordinary care, typically lasts 4–6 years with daily wear. Longevity depends on tanning method (vegetable tanning is more durable than synthetic), leather type (alligator is more resilient than calf), and your usage patterns. Factors such as humidity, direct sunlight exposure, and frequency of use reduce lifespan. A skilled atelier can regenerate leather and adjust length to extend strap life.
