Strap for Chronograph 358 Sa PILOT

The lug width of the Sinn 358.060 is 22 mm. This measurement corresponds to the distance between the two lateral metal pins that hold the strap. All straps compatible with the 22 mm size will mount without any mechanical adjustments.

To maintain the aesthetic and functional coherence of the 358.060, we recommend high-grade alligator (mahogany brown or grey tortoiseshell), vegetable-tanned calf leather, grey or dark blue NATO textile, or FKM rubber. Your choice depends on intended use: alligator and calf for daily elegance, NATO for practicality and versatility, rubber for humid environments.

The strap is replaced using a spring bar tool, a specialized instrument that gently lifts the lateral pins. Position the pointed end under the pin and apply light upward pressure until the hole releases, then remove the old strap. Align the new strap's holes with the pins and press gently until the pin clicks into place. This routine operation requires no watchmaker.

A quality alligator or calf strap, used in rotation with at least one additional strap, maintains structural integrity for 4–6 years of daily wear. Longevity depends on frequency of use, exposure to moisture and heat, and initial leather quality. Vegetable-tanned leather ages more gracefully than synthetic treatments, developing rich patina rather than degrading.

Yes. Any strap designed for 22 mm lugs will mount mechanically without issue. Milano Straps are handcrafted in Italy using premium leather and artisanal finishes, compatible with all Sinn models in this category. Build quality ensures durability equivalent to genuine Sinn straps, with the advantage of colour and material customisation.
