Frequently asked questions

Can I fit a standard strap on the TAG Heuer Connected Watch SBG8A12.BT6239?

No, the bracelet is integrated into the case with a proprietary attachment system. A standard strap won't fit. To change it, I craft a bespoke strap directly in the atelier, shaped to your specific case.

How does the bespoke strap work for the Connected Watch?

It's made entirely at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from your case, calculate the proprietary attachments, and hand-work the leather until it fits perfectly. It's not a modification: it's a piece built for your watch.

What leather do you recommend for the TAG Heuer Connected Watch?

I favour Tuscan leather for this model. The Connected is sporty, modern, with that hybrid ceramic-steel case that speaks of strength and function. Tuscan leather ages beautifully, develops patina that dialogues with the watch's sporty soul, doesn't smother it with false elegance.

How long does a well-made strap last?

With mindful use and a bit of care, leather easily lasts 5 to 8 years. It depends on how often you wear it and how you treat it: protect it from standing water, let it breathe occasionally. The beauty is that it ages. It doesn't die: it changes, tells your story with the watch.

Why is the Connected different from other TAG Heuer sports watches?

Because it's TAG Heuer's bold move into the digital era, keeping the Swiss sporting spirit alive. It's not a common smartwatch: it's a fusion of haute horlogerie and technology. The ceramic and steel case isn't accidental. That's why a strap can't be a generic solution: it must respect this particular architecture.
