Strap for 1858 Automatic Small Second Stainless Steel / Black

The lug width of the Montblanc 1858 115073 is 22 millimetres. This dimension is critical for purchasing a compatible strap: measure the distance between the two lateral lugs of the case to confirm accuracy before ordering.

The choice depends on intended use. For daily elegance, we recommend vegetable-tanned leather or chromium-tanned calf in tobacco-brown or black. For outdoor activities, choose NATO straps in grey weave or vulcanised rubber. Alligator, though refined, is less practical for this technically-orientated model.

Locate the lateral lug pins (metal axes protruding from the case). Using a proper strap removal tool or thin flathead screwdriver, push the pin from one side toward the case interior until it protrudes slightly on the opposite side, then extract it completely. Align the new strap lugs with the holes and reinsert the pin until locked.

Yes, provided the lug width is exactly 22 millimetres. Always verify product specifications before purchase. Artisanal Italian leather straps or premium rubber often offer superior fit and longevity compared to originals, provided dimensions are identical.

A vegetable-tanned leather strap with artisanal construction lasts typically 3-5 years with daily use, developing characteristic patina. Chromium-tanned calf guarantees 5-7 years of durability. Longevity depends on usage frequency, moisture exposure and maintenance: avoid prolonged salt water contact and periodically condition the leather with appropriate products to preserve flexibility.
