Strap for Portofino Chronograph MecaQuartz Stainless Steel / Black / Bracelet

The lug width measures precisely 20mm. This dimension requires straps constructed specifically for this width, as even minor tolerances would generate lateral play between the case lug and the strap. It is not possible to use universal or undersized straps without compromising both the aesthetic and stability of the strap on the wrist.

Tuscan alligator in natural grain represents the aesthetic choice coherent with the lacquered dial: the fineness of the alligator's texture dialogues naturally with the lacquered surface. Vegetable-tanned calf leather is an excellent alternative if you desire an aged patina visible over time. Shell cordovan offers a compact and lustrous texture, whilst NATO is indicated for daily and practical use.

The change requires removal of the spring bars that connect the strap to the case lugs. Use a dedicated tool (spring bar tool) or a small flat screwdriver to compress the internal spring of the pin. Once the pin is extracted, it is possible to remove the old strap and insert the new one by aligning the lateral holes. No specialist tools or expertise are necessary; many watchmakers perform this service free of charge or at minimal cost.

Yes, entirely. Aftermarket 20mm straps are mechanically compatible, provided the internal width is genuinely 20mm. The aesthetic choice depends on personal taste and the selected material. Many owners find artisanal strap quality and customisation freedom superior to standard manufacturer offerings.

The lifespan of a quality artisanal leather strap ranges from 3 to 7 years, depending on daily use, moisture exposure, and the type of tanning. A vegetable-tanned calf leather ages magnificently and can last 10+ years with regular maintenance (light brushing, protection from prolonged rain, natural drying). Shell cordovan, being denser material, tends to last longer. NATO, in fabric and rubber, can resist 5–8 years in intensive use.
