Strap for Grande Seconde 39 Ivory Enamel / White Gold

The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of the Grande Seconde J014014201 is 18mm. This dimension was chosen by Jaquet Droz to maintain harmonious proportions on the 39mm case, ensuring visual balance between dial and crown. The 18mm lug width accommodates a significant variety of aftermarket straps, from <a href="/pages/termine-glossario/alligatore">alligator</a> leather to textile and rubber solutions.

For the white gold version, we recommend straps in <a href="/pages/termine-glossario/concia-vegetale">vegetable tannage</a> leather in bordeaux or cognac brown, which create refined contrast without competing with the precious metal. Alternatively, <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> leather with natural <a href="/pages/termine-glossario/patina">patina</a> enhances the purity of the white dial. For sports contexts, a light grey NATO maintains elegance without betraying the watch's dress vocation.

Strap replacement requires a spring bar tool or dedicated extraction implement. Position the watch on a soft cloth to avoid scratches. Locate the two thin spring bars beneath the lugs: apply gentle pressure with the tool to compress the internal spring and lever carefully. Once one spring bar is freed, extract the strap. Insert the new strap by aligning the lug holes with the spring bars, then allow them to snap into place. If inexperienced, we recommend seeking professional assistance.

All straps with 18mm attachment points are compatible. Milano Straps offers a curated selection of <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-18mm">18mm straps</a> in leather, textile, rubber and alligator skin. It is essential to verify that the strap respects the exact width: a marginally narrower or wider lug attachment can cause unwanted play or prevent insertion. Best results are achieved with straps crafted by artisans who understand Swiss dress watch proportions.

Longevity depends on tanning quality and usage intensity. A high-end vegetable-tanned leather strap, with moderate daily wear, lasts 3-5 years before showing aesthetic ageing signs (surface creasing, fading). The <a href="/pages/termine-glossario/patina">patina</a> that develops is desirable: it imparts character and uniqueness. To extend service life, avoid prolonged contact with water, salt sweat and extreme humidity. Periodic maintenance with natural balms preserves elasticity and lustre. Milano Straps recommends owning at least two straps to rotate usage and reduce continuous mechanical stress.
