Frequently asked questions

What is the exact lug width of the Tissot Carson T71.3.442.42?

The lug width of the Tissot Carson T71.3.442.42 is precisely 18mm. This measurement is taken between the protruding spring bar pins on the case. Use a digital calliper to verify accurately: 18mm excludes compatibility with 16mm, 20mm, or other widths, ensuring perfect fit.

Which strap is recommended for this yellow gold model?

For the Carson T71.3.442.42 in yellow gold, we recommend alligator leather in cognac or tobacco tones, which harmonises naturally with the metal's warmth. Valid alternatives include vegetable-tanned calf grain-finish leather (black for formal, cognac for versatility), or NATO in cream/smoke grey for casual contexts. Flat rubber is not advised: the Carson is not sportwear and would be visually compromised.

How do I change the strap on the Tissot Carson T71.3.442.42?

The Carson T71.3.442.42 features an integrated bracelet originally, but the spring bars are standard. To replace: position the watch case-down, use a spring bar tool to compress the underlying pin, gently remove the old strap, align the new strap openings, and reinert the pin until it clicks into position. We recommend having a qualified watchmaker perform this operation to avoid scratching the gold case.

Is there an aftermarket strap compatible with the Tissot Carson T71.3.442.42?

Yes, any strap with 18mm lug width is compatible with the Carson T71.3.442.42. At Milano Straps you will find a curated collection of artisanal leather straps (alligator, calf, vegetable-tanned), NATO, and rubber—all available in 18mm width. Straps are ready to ship and customisable online according to colour and finish preferences.

How long does a leather strap last on the Tissot Carson T71.3.442.42?

A premium leather strap—such as alligator or vegetable-tanned calf—has an average lifespan of 3–5 years with daily wear, depending on climate, perspiration, and cleaning frequency. Ageing is part of the beauty: leather develops patina and character. To extend longevity, avoid prolonged water immersion, dry promptly after rain, and occasionally apply natural-based conditioning balm. Accelerated wear indicates replacement is needed.
