Frequently asked questions

What is the lug width of the TAG Heuer Connected Watch SBG8A13.EB0238?

The lug width of the TAG Heuer Connected Watch SBG8A13.EB0238 is 20mm. This measurement is critical for aftermarket strap compatibility and must be verified with precision using a digital calliper, measuring from the internal hole of one spring bar to the other.

What is the best strap material for the TAG Heuer Connected Watch SBG8A13.EB0238?

The choice depends on usage and desired aesthetic. Polished alligator offers formal elegance and patina development over time. Vegetable-tanned calf communicates tradition and ages with character. NATO in cordura guarantees versatility and sporting practicality. FKM rubber is ideal for intense daily use without maintenance.

How do you change the strap on the TAG Heuer Connected Watch SBG8A13.EB0238?

The strap is attached to the case through two spring bars. To remove it, use a spring bar tool: gently push the spring inward to free it from its seat. Insert the new strap by aligning the keeper loops with the spring bar holes and push until you hear a click. Verify the fit before wearing.

Can I use compatible aftermarket straps for the TAG Heuer Connected Watch SBG8A13.EB0238?

Yes. All straps with a 20mm lug width are compatible. Milano Straps straps are crafted in fine leather or technical materials, customisable in sizing and guaranteed for 18 months. Casati Milano atelier also offers bespoke service with direct leather selection.

What is the average lifespan of a leather strap for the TAG Heuer Connected Watch SBG8A13.EB0238?

The lifespan depends on usage frequency, climate and maintenance. A quality alligator or calf strap has an average life of 2-4 years with moderate daily use. Vegetable tanning tends to age better over time. Milano Straps carry an 18-month warranty and can be replaced individually.
