Strap for Terranaut II Trail Black / Strap

The lug width of the Terranaut M1-40-34/1-NB is 22mm. This dimension is specifically designed to maintain proportional balance with the 44mm case diameter, providing access to a wide range of both artisanal and industrial straps.

For a tool watch of this calibre, we recommend first and foremost a vegetable-tanned leather strap from Florence – the raw texture and natural patina amplify the technical identity of the watch. Alternatively, a polished alligator strap in dark tones offers elegance without compromise, whilst a robust NATO fabric strap emphasises the expedition-ready character of this model.

To change the strap, use a spring bar tool or a strap removal tool to gently push the spring bars that secure the strap to the lugs. Align the new 22mm strap with the lugs and re-insert the spring bars until you hear or feel a click. Verify that both bars are fully seated.

Yes, the 22mm lug width is a widespread standard. Any artisanal or industrial strap with 22mm spring bar dimensions is compatible. We recommend verifying that the spring bars have the same diameter (typically 1.8mm) to avoid excessive play. Milano Straps offers a curated selection of certified straps for this size.

A high-quality vegetable-tanned leather strap, subject to ordinary wear (daily use), has an average lifespan of 3–5 years. Longevity depends on exposure to moisture, perspiration, heat, and cleaning frequency. A NATO or FKM rubber strap, conversely, guarantees superior durability – up to 7–10 years – because they resist moisture far better and do not develop the cracks that leather straps are prone to.
