Strap for Doxa Sub 200 T.Graph II

The Doxa Sub 200 T.Graph II features a 20mm lug width, a specific measurement that represents the ideal compromise between oversized military lugs (22–24mm) and classic chronographs. This dimension allows the mounting of moderately thick straps whilst maintaining visual proportions balanced to the 42mm case diameter.

The choice depends on intended use and aesthetic context. For formal elegance, we recommend alligator with vegetable tanning or full-grain calf leather in black or dark brown. For tactical and aquatic environments, nylon Cordura NATO or FKM rubber straps offer superior grip and rapid drying. All materials must be 20mm to fit perfectly.

The strap is replaced by removing the spring bars (pins) that connect the strap to the case lugs. Using a dedicated tool or thin flat blade, compress the internal spring of the pin by applying lateral pressure, then extract the pin to release the old strap. Insert the new 20mm strap by positioning the pins in their case recesses and checking for play.

Any 20mm strap is compatible with the Sub 200 T.Graph II, provided the case lugs remain intact and the spring bars function correctly. On milanostraps.it you will find a complete selection of 20mm straps in leather (alligator, calf, shell cordovan), NATO, and FKM rubber, all tested to fit flawlessly.

Durability varies according to material, usage frequency, and environmental conditions. Vegetable-tanned alligator achieves 3–5 years of daily wear whilst developing a natural patina. Full-grain calf, if dried regularly after water exposure, can last 4–7 years. Nylon NATO straps exceed 10 years without deterioration. FKM rubber maintains optimal characteristics for 5–8 years, especially when subjected to frequent thermal variation.
