Strap for 1858 Manual Small Second Stainless Steel / Blue

The Montblanc 1858 113702 features a lug width of 22mm. This measurement represents the distance between the two lugs on the watch case and is essential for selecting a compatible strap. To verify, measure the space between the lugs directly using a digital calliper or ruler.

For this model, we recommend an alligator strap in honey brown or cognac tones, which enhances the classic-adventurous character of the watch. Alternatively, a vegetable-tanned Tuscan leather in natural brown is ideal for those who appreciate colour evolution over time. For sporty use, a navy blue NATO strap or a black vulcanised rubber deployante offers practicality and robustness.

Place the watch on a soft surface. Using a spring bar tool (a specific tool for removing lugs), gently press the small spring inside the lug, then extract the old strap. Insert the new strap ensuring that both ends are positioned symmetrically in the lugs, then release the spring until you hear the locking click. Always verify that the strap is securely fastened before wearing the watch.

Yes, any strap with a 22mm lug width is mechanically compatible with the Montblanc 1858 113702. However, to ensure aesthetic harmony, we recommend noble materials such as alligator, shell cordovan or vegetable-tanned leather. Also verify that the strap thickness does not exceed 2.5-3mm to ensure smooth passage through the lugs without excessive play.

The lifespan of a leather strap depends on usage and environmental conditions. A high-quality alligator or shell cordovan strap, worn daily under normal conditions, lasts 3-5 years before showing significant signs of wear. Vegetable-tanned leather rapidly develops a fascinating patina in the first 6-12 months, after which its appearance stabilises. Prolonged exposure to humidity or saline environments reduces overall durability.
