Part of the Service series and an original Haveston design, Roundel ’43 draws from the Army-Navy AN-I-9 aeronautical specification introduced in August 1943. This was the version of the USAAF roundel that added white side bars for better visibility at a distance, along with a blue outline that varied slightly depending on where it was used. (Red was intentionally left out.) The A2 single-pass layout keeps the profile low and close to the wrist, and a sliding keeper secures the strap tail cleanly.

Material & feel

Constructed from robust 1.3mm heavy-weave polyamide with a firm, structured feel. The surface has a matte finish with a slightly coarse texture. Reinforced setting holes and a strengthened tail improve durability. Finished with a stainless steel buckle.

Fit guidance

Single-pass A2 configuration keeps the watch closer to the wrist than double-layer pass-through straps. The heavier weave adds more structure than thinner nylon straps. Multiple adjustment holes provide a broad fit range, while the sliding keeper helps secure excess strap length.

About the brand

Haveston is a British strap maker built around a clear point of reference: the kind of equipment issued to be used, not admired. Its designs draw from vintage military and industrial gear, where materials, construction, and layout were shaped by function first.

The brand takes cues from historical use across aviation, space exploration, and military service. That influence shows up in the details, from single-pass layouts to hook-and-loop closures and straightforward two-piece straps. The result is a range focused on durability, simplicity, and the same practical character found in the original equipment.
