Strap for 1858 Chronograph Tachymeter Bronze Only Watch 2017

The lug width of the Montblanc 1858 ref. 118775 is 20 millimetres. This dimension is essential to ensure you purchase a compatible strap and achieve proper tension on the wrist. Always measure the distance between the attachment pins of your case before ordering a new strap.

The Montblanc 1858 118775 pairs exceptionally well with three strap categories. Alligator leather with vegetable tanning represents the pinnacle of contemplative luxury, enhancing the natural bronze patina. NATO webbing in technical fabric offers operational practicality and authentic explorer aesthetics. Smoke-grey rubber delivers water resistance and maximum functionality in extreme environments. Your choice depends on intended use: formal, exploratory, or mixed-duty wear.

Strap replacement on the 118775 is accomplished by removing the spring bars (attachment pins) located at the case extremities. Use a dedicated strap removal tool or spring bar press, gently pushing the spring inward to release the pin. Insert the new 20mm strap by aligning the lateral holes to the pins, then activate the return spring. This operation demands precision to prevent case damage. We recommend professional intervention from a qualified watchmaker if inexperienced.

Yes, any quality 20mm strap is compatible with the 118775, provided it is manufactured by specialised artisanship. Verify that the upper and lower lugs are equipped with quality spring bars (stainless steel or titanium) and that stitching is uniform and resilient. Artisanal straps in alligator, calf leather with vegetable tanning, or ostrich skin are highly recommended to honour the case's construction quality.

A quality artisanal leather strap has a lifespan of 3–5 years with daily regular use, varying according to tanning method employed. Vegetable-tanned leather tends to age more slowly and develops an elegant patina. Alligator, being more robust, may last 5–8 years. Durability depends on ambient humidity, bodily perspiration, strap replacement frequency, and maintenance regimen. Annual stitching inspection and natural wax treatment extend longevity substantially.
