Strap for Portofino Automatic Yellow Gold / Champagne / Strap

The lug width of the Portofino IW3513-07 is 18mm, corresponding to the distance between the two case lugs. This intermediate size is characteristic of this specific reference and requires straps specifically constructed for this width, incompatible with standard 16mm or 20mm sizes.

Alligator leather represents the optimal choice for the yellow gold Portofino, thanks to its regular texture that complements the sobriety of the case. Shell cordovan is an excellent alternative for those seeking greater luminosity and superior ageing characteristics. Vegetable-tanned or chromium-tanned calf leather in brown or black tones offers versatility, whilst NATO straps are inadvisable as they would diminish the visual impact of the 34mm case proportions.

To change the strap, position the watch on a stable support with the case facing upward. Use a dedicated spring bar removal tool to compress the internal spring of the lug, then gently extract the old strap. Align the holes of the new 18mm strap with the case lugs, insert one side first, then secure the other side, ensuring the spring is correctly positioned. Avoid using improvised tools that could scratch the gold.

Yes, any quality strap constructed with 18mm lug width is compatible with the Portofino IW3513-07. Ensure the strap is supplied with a deployant clasp or buckle in stainless steel or gold, depending on the tone chosen, and that the thickness of the leather is consistent with the minimalist proportions of the case. Customizable artisanal straps offer the possibility of perfectly adapting colour, leather type and finishes to your preferences.

A quality natural leather strap, subjected to regular maintenance, typically lasts 3-5 years with daily use. Durability depends on the tanning process (vegetable-tanned leather ages better than chrome-tanned), frequency of use and exposure to humidity and sunlight. Alligator and shell cordovan, due to their more resistant fibrous structure, tend to exceed 5 years easily. Proper drying after humidity exposure and periodic conditioning with natural oils significantly extend the life of the strap.
