The Aquaracer CAP2110.BA0833 (aka: CAP2110BA0833, CAP2110), seen from the bench

The TAG Heuer Aquaracer CAP2110.BA0833 is the contemporary evolution of one of the Swiss maison's most iconic sports lines, launched in 2004. This model features a robust stainless steel case measuring 42 millimetres in diameter with a rotating bezel, water resistance to 300 metres, and a screw-down crown. The internal movement is the TAG Heuer Calibre 16, an automatic calibre with hours, minutes, small seconds, date and integrated chronograph functions. The lug width is 20 millimetres.

Frequently asked questions

What is the lug width of the TAG Heuer Aquaracer CAP2110.BA0833?

The TAG Heuer Aquaracer CAP2110.BA0833 features a lug width of 20 millimetres. This measurement represents the internal distance between the two lugs that connect the case to the original bracelet. Any strap compatible with the 20mm specification will fit perfectly into the case lugs, ensuring secure installation without any play.

What is the best strap for the TAG Heuer Aquaracer CAP2110.BA0833?

The choice depends on usage and personal aesthetic preference. For formal occasions, we recommend alligator or shell cordovan, which create an elegant contrast with the sporty stainless steel case. For daily wear and diving activities, NATO canvas or FKM rubber maintains the tool watch character. Vegetable-tanned calf leather offers the ideal compromise between elegance and versatility, developing a beautiful patina over time.

How do you change the strap on this watch?

To change the strap on the TAG Heuer Aquaracer CAP2110.BA0833, you must remove the two spring bars (pins) that connect the bracelet to the case lugs. Using a dedicated spring bar tool, gently push the pin from the opposite side until it releases. Repeat for the second pin, then align the new strap's holes with the lugs and reinsert the spring bars until fully secured.

Are aftermarket straps compatible with the TAG Heuer Aquaracer CAP2110.BA0833?

Yes, all aftermarket straps with a 20mm lug width are fully compatible with the TAG Heuer Aquaracer CAP2110.BA0833. It is essential to verify that your chosen strap has the correct lug width (20mm measured between the internal attachments). Milano Straps offers an extensive selection of straps in alligator, calf leather, shell cordovan, and technical materials, all crafted to Swiss quality standards.

How long does a natural leather strap last on this watch?

The durability of a leather strap depends on the tanning method and frequency of use. High-quality vegetable-tanned leather straps typically last 3-5 years with moderate daily wear. Constant exposure to water—whilst the TAG Heuer Aquaracer is water-resistant to 300m—may reduce the leather's lifespan. Shell cordovan straps, due to their fibre density, offer superior longevity. Milano Straps provides an 18-month warranty on all straps crafted by the Casati Milano atelier.
