Haveston IVA Series STS Watch Strap

Alex, the founder of British strapmaker Haveston, is fueled by a passion for horology and history. Throughout Haveston's varied and growing portfolio, its designs are defined by a focus on the honest utilitarian character of vintage military industrial equipment used by service personnel for aviation, space exploration, combat and other purposes.

If Haveston's commitment to continuous refinement and innovation is any indication, we can expect much more from the company -- with one underlying idea. According to Alex: "At the end of the day, it always comes back to that service-driven purpose, regardless of whether that is to your community, family, or the world. Having a little reminder of that on your wrist is quite special."

Haveston's IVA collection is inspired by the original vintage space-flown straps used by astronauts to wrist-mount mission tools. The utilitarian construction lends itself to a variety of lunar, pilot and other tool watch styles. IVA makes a great dive strap!

The Space Transportation System (STS) was the original reusable crewed space vehicle, first envisioned in 1969 in an era where rockets and capsules were expendable single-use vehicles. Formally commencing in 1972 with its first flight in 1981, the Shuttle (sometimes referred to as a “Space Truck”) facilitated access to low Earth orbit and the construction of the ISS. Upon its retirement in 2011, it had served twice as long as originally intended.

Inspired by the pioneering days of the reusable crewed space vehicle, Haveston's STS IVA strap features a versatile olive drab nylon exterior with black lining, mission patch icon and historical tribute markings.

Double layers along with a hook-and-loop configuration give the IVA a higher side profile than other Haveston straps. Full-length webbing lining provides uniform structure and support, while the high-grip rubber locking keeper ensures secure closure (spare also included). The one-piece configuration provides security in the event of spring bar failure, and the robust stainless steel bead-blasted hoop buckle makes this strap a highly secure mission tool.
