Prometheus Design Werx Ti-FXDS Strap 22mm - Gray Short

The 22mm width, Gray, Short length Ti-FXDS is a single-pass watch strap built around a Grade 5 6AL-4V titanium buckle, heavy-duty elastic rigger's webbing, and a high-cycle hook and loop closure. Conceived as a field-ready evolution of the classic military nylon watch strap, it was originally developed for fixed-bar watches like the Tudor FXD and remains the only hook and loop strap of its type to pair titanium hardware with stretch nylon construction.

The single-pass architecture keeps the underside of the watch case clean and unobstructed. Unlike double-layer NATO configurations, the Ti-FXDS threads through the watch's fixed or spring bar lugs in one continuous piece, then secures via hook and loop closure with a sewn nylon keeper loop for additional tail retention. The keeper slides over the webbing and can be removed if not needed.

Webbing is woven nylon with spandex, providing longitudinal stretch for wrist-conforming fit across the full adjustment range. The Grade 5 (Ti-6Al-4V) titanium buckle is fully non-magnetic and corrosion-proof. PDW specifies non-magnetic titanium hardware across its entire watch strap line as a compatibility requirement for wrist-mounted compasses. Non-ferromagnetic hardware eliminates the risk of compass needle deviation caused by adjacent metallic fields. The same property makes it suitable for dive watch applications where saltwater corrosion resistance is a requirement.

The hook and loop closure is rated for high-cycle use: over 13 years at twice-daily cycling, over 9 years at three cycles per day.

COLORWAY

Gray — Battleship gray woven nylon with spandex. Neutral against both stainless and titanium case finishes.

COMPATIBILITY

Designed for tool watches and dive watches. Fits fixed-bar and spring bar lug configurations. Not compatible with integrated bracelet lug systems. 20mm strap width fits watches with 22mm lugs. Representative compatible references: many Tudor models such as the Black Bay 41mm, FXD, Seiko SKX, Prospex and Turtles, Sinn U1 and many field watches across the spectrum. If your watch takes a standard 22mm, the Ti-FXDS in 22mm will fit.
