Strap for Chrono XL Khaki PVD / Black

The lug width of the Tissot XL T116.617.37.057.01 is 22mm. This measurement is critical for ensuring mechanical compatibility between the strap and the case lugs. A 22mm lug width strap fits precisely within the case lugs without lateral play, guaranteeing secure attachment and aesthetic coherence. The lug width can be verified by measuring the internal distance between the lugs using a calliper.

For the Tissot XL T116.617.37.057.01, leather straps in calf, alligator, or crocodile are recommended for formal contexts, whilst NATO straps in premium fabrics or elastomers are ideal for daily sports use. The brushed stainless steel case pairs exceptionally well with vegetable-tanned leathers in terracotta or aged brown tones, whilst for tactical deployment a navy or black NATO provides functional synergy. Butyl rubber straps are advised for humid environments or water immersion, leveraging the movement's water resistance to 100 metres.

Strap replacement requires a spring bar removal tool or dedicated stylus. Position the chronograph on a stable surface, insert the flat end of the tool into the lateral access hole of the lug, and gently lift the spring bar securing the strap. Once released, the existing strap detaches. Align the new 22mm strap with the lugs and reinsert the spring bar, confirming positive engagement. If specialist tools are unavailable, consult a qualified atelier to prevent case damage.

Aftermarket straps must strictly observe the 22mm lug width specification. Options include Italian vegetable-tanned leather, alligator, premium shell cordovan, or NATO in recycled plastic filament. Milano Straps offers a curated collection of bespoke 22mm straps, manufactured to Swiss construction standards, with natural fibre finishes and colourways ranging from classical navy blue to contemporary military green. Leather quality directly influences longevity and tactile comfort: vegetable-tanned leathers exhibit superior patina development, acquiring distinctive character over time.

Leather strap longevity depends on usage frequency and tannery quality. Vegetable-tanned leather, as employed in Milano Straps production, provides average durability of 2–3 years under intensive daily use, extending to 5–7 years with moderate use and regular maintenance. Critical factors include exposure to water, perspiration, ultraviolet radiation, and buckle finish quality. NATO straps in regenerated filaments offer superior lifespan, 5–10 years, owing to absence of substrate degradation, requiring only periodic washing. The patina that develops on quality leather represents added value, transforming the strap into a personalised object throughout its service life.
