RAF Sea Scheme tones in muted green and grey striping.
Sector takes its name from the RAF’s Battle of Britain air defense system, and pulls its color palette from the 1941 Sea Scheme used on Spitfire fighters. The mix of muted greens and greys comes through as a layered stripe pattern that feels grounded and restrained rather than high contrast. It has a quiet, utilitarian look that complements matte dials, brushed cases and field-style watches. The A2 single-pass layout keeps the profile low, with a sliding keeper to hold the tail in place.
Constructed from robust 1.3mm heavy-weave polyamide with a firm, structured feel. The surface has a matte finish with a slightly textured hand. Enhanced versions have reinforced setting holes and tail. Finished with a stainless steel buckle.

Single-pass A2 layout reduces bulk under the case and keeps the watch closer to the wrist. The structured weave helps it hold shape once fitted. Multiple adjustment holes provide a wide fit range, and the sliding keeper keeps excess strap secure and tidy.

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.
