Ultrafine navy nylon based on WWII ANA623 Sea Blue.
The inspiration for Haveston's Sea Blue Parade strap comes from ANA623, the deep navy used on WWII U.S. naval aircraft. The strap's ultrafine weave and matching border trim gives it a smooth, even surface and a slightly silky feel compared to standard nylon. Sea Blue works well with blue-accented watches, monochrome dials, and heat-blued hands. The extended underlayer can be removed to convert it into a single-pass configuration, giving the option of a lower profile when needed.
Constructed from 1.2mm ultra-fine weave polyamide. The material has a smooth, tightly woven surface with a soft, flexible feel. Its reduced thickness keeps it pliable while maintaining structure. Available with either a brushed or polished stainless steel buckle.
Thickness: approx. 2.4mm
Edges: Raw
Stitching: Blue
Sheen: Semi-gloss
Buckle: Available in brushed stainless steel or polished stainless steel (see options)
Spring bars: Standard (free pair included)
Extended underlayer design provides added security by keeping the watch head anchored even if a spring bar fails. This also creates a slightly more substantial profile. The removable underlayer allows conversion to a single-pass setup for a lower profile. A sliding keeper makes it easy to position and secure the tail end without fixed loops.

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.
