Strap for Portofino Automatic Stainless Steel / Silver - Breguet / Strap

The Portofino IW3513-23 features 18-millimetre lugs. This specification is unique to this reference, and the strap must fit precisely between the lugs. Always measure between the innermost anchor points to avoid oversizing errors.

Selection depends on usage and desired aesthetics. For formal occasions, African alligator or vegetable-tanned calf leather honour the watch's discreet elegance. For daily wear, satin-finish vulcanized rubber or neutral NATO fabric offer practicality. Shell cordovan works on wrists with specific proportions.

Use a spring bar tool to gently compress the horizontal pins (spring bars) running through the lugs. Remove the old strap and insert the new one, ensuring the pins click into their slots. Verify the strap is centred between the lugs. Seek professional assistance if inexperienced to prevent scratching the case.

Yes, any 18mm strap is compatible. Ensure the width is precise: 18mm measured at the narrowest points of the lugs. Check the compatible straps section online for styles that harmonise best with the 34mm case proportions.

A quality leather strap, whether vegetable-tanned or alligator, typically lasts 3–5 years with daily wear. Durability depends on humidity, sunlight exposure and frequency of use. Naturally tanned leathers tend to develop character through patina rather than deteriorate. Minimal maintenance—cleaning and occasional conditioning—extends strap lifespan considerably.
