Strap for SUB 300 Carbon Caribbean

The lug width of the Doxa SUB 300 822.70.201.20 is precisely 20 millimetres. This measurement should be verified using a digital calliper, positioning the measuring points between the lug pins and excluding any case shoulders or protective elements. All straps specified for 20mm are fully compatible with this model.

The choice depends on intended use. An alligator leather strap with vegetable tanning creates elegant contrast against the modern titanium-carbon case and develops natural patina over time. For frequent diving, a rubber strap with textile reinforcement offers practicality and superior saltwater resistance. A Cordura NATO strap provides safety redundancy: should the lug pin loosen, the strap remains secured to the wrist during underwater operations.

The Doxa SUB 300 uses spring bar pins for strap attachment. Acquire a spring bar removal tool. Position the watch with the lugs facing upward, insert the tool into the small groove on the pin and apply gentle downward pressure whilst withdrawing the old strap. Align the new strap holes with the pins and reinsert the pins until they click. Verify the strap is securely fastened before use.

Yes, all artisanal straps specified for 20mm are compatible with this model. Ensure the pin diameter of the strap matches the original Doxa pins (typically 1.6mm stainless steel). Straps in vegetable-tanned leather, rubber and NATO certified for 20mm will guarantee perfect fit and reliability during diving operations.

A vegetable-tanned leather strap subjected to frequent saltwater immersion maintains structural integrity for 18–24 months with proper care. Durability depends on immersion frequency and subsequent drying procedures. For occasional use (sporadic immersions), leather may remain serviceable for 3–4 years. After each immersion, dry the strap thoroughly and apply light natural oil treatment every six months. For weekly diving, a rubber strap represents the most durable and practical option.
