Strap for Star Roman Chronograph GMT Automatic Silver

The lug width of the Montblanc Star 36967 is 22mm, measured from the inner edge of one lug to the other. When ordering a replacement strap, ensure it is explicitly specified as 22mm to guarantee perfect compatibility without mechanical play.

Vegetable-tanned calf leather is the ideal choice for aesthetics and longevity: it develops a natural patina that complements the ageing of the stainless steel case. For sports use, FKM rubber is excellent; for formal occasions, genuine alligator guarantees durability exceeding 20 years.

Remove the old strap by slipping the lugs from their seats—occasionally a spring bar tool, a small metal lever, is required to lift the lug from inside the case. Once the lugs are freed, insert the new strap by aligning the 22mm width precisely and reposition the lugs firmly in their seats. Avoid excessive torque.

No, provided the strap is genuinely 22mm. Oversized straps may not fit into the lugs; undersized straps will create superficial play. A skilled craftsman will always verify compatibility before installation. Avoid DIY if inexperienced.

A high-quality vegetable-tanned leather strap lasts 5–8 years with moderate daily wear; with regular care (occasional cleaning, storage away from extreme humidity), durability can extend to 10–12 years. Alligator lasts 15–20 years. FKM rubber resists 3–5 years before hardening.
