Aquagraph

The Tag Heuer Aquagraph was engineered as a true tool watch for professional divers, earning its reputation through rigorous field use and a distinctive set of features. Released in the early 2000s as part of the 2000 Series, it’s notable for being one of the few chronographs rated to 500 meters, with pushers that can be safely operated underwater. This model is especially sought after by collectors who appreciate purpose-built dive chronographs that don’t compromise on either functionality or design.

The key reference is CN211A, powered by the Calibre 60 automatic movement, which is based on the ETA 2892 with a Dubois Dépraz chronograph module. Compared to other Tag Heuer divers, the Aquagraph stands out with its yellow-tipped central minute counter, bold hands, and a unique locking bezel. Prices vary depending on condition, presence of the original rubber strap or bracelet, and completeness of box and papers—full sets command a premium, especially if the original rubber strap isn’t cracked or degraded.

When considering an Aquagraph, inspect the integrity of the pushers and crown, as replacements can be hard to source. The rubber strap is a known wear point; sourcing an original can be costly, so factor that into your budget. The CN211A is less commonly seen than other 2000 Series models, making it a compelling choice for those after a distinctive, high-spec Tag Heuer diver with real professional pedigree.
