Strap for Carson Automatic 40 Rose Gold / Black / Strap

The lug width of the Tissot Carson T907.407.76.058.00 is 20mm. This measurement is taken by positioning a calliper between the two inner shoulders of the lug attachment, without forcing. It is the standard specification for 40mm cases in this collection, ensuring balanced proportions between the case diameter and strap width.

The ideal strap depends on use case: for formal occasions, we recommend alligator in cognac or brown tones, which enhances the warm reflections of rose gold. For office wear, black or dark blue leather with a rose gold deployante buckle offers discretion. For daily use, black rubber or cotton NATO provide comfort and practicality without aesthetic compromise. The strap colour should harmonise with the warm rose gold tone of the case.

The Carson's strap is changed via a removable spring bar (pin), not via bayonet-style lugs. Position the watch on a soft pad, locate the spring bar connecting the strap to the lugs, and gently push it inward using a dedicated tool (spring bar tool) until it protrudes. Remove the old strap, align the new strap's holes with the spring bar, then press firmly until you hear a click. Verify the strap is secure before wearing the watch.

Yes, provided it is certified for 20mm lug width. Quality aftermarket straps (such as artisanal alligator or calf leather) are fully compatible with the Carson, as long as they respect the exact width. A 20mm strap will insert perfectly into the lugs without lateral gaps. We recommend always verifying specifications before purchase and choosing specialised brands to ensure finishes consistent with your watch's quality.

Leather strap longevity depends on the type of tanning and usage pattern. A quality artisanal alligator or calf leather, vegetable-tanned, typically lasts 3–5 years with daily wear. Leather wears primarily at flex points (the keeper and buckle area), whilst the rest of the surface develops natural patina. Factors such as humidity, sun exposure, and frequency of use influence lifespan. A robust, well-maintained leather strap, subjected to periodic care (hydration, cleaning), can easily exceed 5 years of conscious use.
