Introducing the Doxa SUB T.Graph II ‘Great White’ Topper Edition

The return of the Doxa SUB T.Graph earlier this year marked the comeback of one of the brand's most celebrated dive chronographs. Now, Doxa and Topper Jewelers build on that momentum with the SUB T.Graph II "Great White" Topper Edition, a 100-piece limited edition inspired by the rugged Farallon Islands off the coast of Northern California and the great white sharks that inhabit the surrounding waters. Developed exclusively for the retailer, the new model continues the its established "Great White" series, combining a distinctive white-and-blue color scheme with details tailored to professional diving. Like previous editions, it also supports marine conservation, with a portion of the proceeds benefiting the Greater Farallones Association, which works to protect the diverse ecosystem of the Greater Farallones National Marine Sanctuary.

A Purpose-Built Dial

The fully luminous white dial follows a classic bi-compax layout, combining high contrast with excellent legibility. It displays the hours and minutes alongside a running seconds subdial at 9 o'clock and a 30-minute chronograph counter at 3 o'clock. The central chronograph seconds hand completes the display, while the absence of a date preserves the dial's symmetry and keeps distractions to a minimum.

As with every SUB, readability is paramount. The oversized minute hand, bold hour hand, and arrow-tipped central chronograph seconds hand are all blue lacquered and instantly distinguishable thanks to their different shapes and proportions. Generous Superluminova BGW9 on the dial, hands, and applied hour markers ensures excellent visibility in low light and underwater, making elapsed dive time easy to monitor at a glance. A flat, anti-reflective sapphire crystal references the design of the original, vintage 1968 T.Graph.

The Signature Dive Bezel

Surrounding the dial is one of DOXA's defining features: the unidirectional rotating bezel with its deeply serrated edge for secure operation, even while wearing diving gloves. Unlike a conventional timing bezel, it incorporates Doxa's patented dual-scale system, combining a standard elapsed-time scale with the brand's signature no-decompression scale based on U.S. Navy dive tables. This allows divers to monitor both dive duration and maximum no-stop dive times directly from the bezel without additional calculations. On the Great White edition, the engraved scales are filled with navy-blue lacquer, matching the dial accents and reinforcing the watch's distinctive maritime color scheme.

Built for Diving

The SUB T.Graph II retains the functional characteristics that made the original model a favorite among divers. Water-resistant to 200 meters, the 42mm brushed steel case houses the Sellita SW 510 Elaboré automatic chronograph movement with a 50-hour power reserve. The watch comes fitted with Doxa's "Beads-of-Rice" bracelet featuring a folding clasp with a ratcheting wetsuit extension. An additional navy-blue FKM rubber strap with a steel folding clasp is included. Limited to 100 individually numbered pieces, it is priced at $4,690.
