When Doxa unveiled the original SUB 200 T-Graph back in 1969, it immediately established a bold new benchmark for high-utility dive chronographs. Designed not as an exercise in technical extravagance, but as a purposeful instrument for aquatic professionals, the T-Graph combined Doxa’s legendary high-visibility dial layout with a dual-register chronograph.
After decades residing in horological lore and brief, highly coveted limited-edition runs, the Genevan brand officially revives the line with the permanent Doxa SUB 200 T-Graph II Professional.

Refined Cushion Geometry & Historic Ergonomics
The defining characteristic of any Doxa diver is its distinctive tonneau cushion case, and the T-Graph II refines those classic proportions for superior wrist ergonomics.
Trimming the case down to 42mm in diameter and 14.6mm in depth (compared to previous 43mm iterations), the watch settles comfortably on the wrist without sacrificing its robust presence. Crucially, the lug-to-lug span remains a tight 44.5mm, allowing the 200-metre water-resistant steel chassis to wear significantly smaller than its on-paper specs suggest.
Framing the sapphire crystal display is Doxa’s patented unidirectional rotating bezel, featuring the dual US Navy no-decompression dive table scale engraved in black and orange.
Every surface of the case showcases a thoughtful mix of satin-brushed finishing and polished bevels, engineered to withstand the rigours of deep-water exploration.
High-Visibility “Professional” Dial & Bi-Compax Utility
Doxa’s iconic “Professional” orange dial was scientifically developed in the late 1960s to offer maximum contrast in murky underwater conditions.
On the T-Graph II, that vibrant hue serves as the backdrop for a clean bi-compax chronograph layout. A 30-minute counter sits at 3 o’clock, balanced by running sub-seconds at 9 o’clock and a discreet date window nestled at 6 o’clock.
“By sizing down the cushion case and housing a Swiss SW510 automatic chronograph behind its iconic orange dial, Doxa resurrects a true underwater legend.”
Baton hour markers and the signature oversized black hour and minute hands are coated with high-grade Swiss Super-LumiNova, ensuring instant legibility when diving below ambient light thresholds.
Swiss Sellita SW510 Calibre Mechanics
Beating inside the screw-down steel case is the automatic Sellita SW510 chronograph movement.
Operating at 28,800 vibrations per hour (4Hz) with a 56-hour power reserve, this workhorse calibre provides smooth pusher engagement and reliable timing precision.
Available on Doxa’s iconic stainless steel “beads of rice” bracelet or a colour-matched orange rubber strap, the Doxa SUB 200 T-Graph II Professional stands out as a triumphant revival of a vintage tool watch icon.
