Frequently asked questions

What is the lug width of the Montblanc Timewalker 113877?

The lug width of the Montblanc Timewalker 113877 is 22mm. This dimension is measured precisely between the spring bars that connect the case to the strap using a digital calliper. It is essential to verify this measurement before purchasing an aftermarket strap to ensure complete compatibility.

What is the best strap for the Timewalker 113877?

The best strap depends on intended use. For formal and business contexts, we recommend leather crafted from alligator or calf with vegetable tanning in dark colourways (dark brown, black, cognac). For sport and everyday use, a NATO canvas or vulcanised rubber strap with minimum thickness of 1.6mm maintains aesthetic balance without functional compromise.

How do you change the strap on a Montblanc Timewalker 113877?

Strap replacement is straightforward: use a spring bar tool to gently extract the pins from the lugs, remove the old strap and insert the new one by aligning the holes with the pins. Ensure the pins click securely into place on both sides. The operation requires less than five minutes with no specialist tools required.

Are aftermarket straps compatible with the 22mm lug width of the Timewalker 113877?

Yes, all straps with 22mm lug width are compatible. Milano Straps offers a comprehensive selection of handcrafted straps in leather, NATO and rubber specifically calibrated for this dimension. Always verify that the strap is genuinely 22mm—even a slightly larger dimension could create tension during assembly.

How long does a leather strap last on the Montblanc Timewalker 113877?

A quality leather strap with vegetable tanning, subjected to daily use and minimal maintenance (periodic cleaning, occasional application of specialist cream), maintains functionality and aesthetics for 4-6 years. The patina that develops over time represents a desirable characteristic, not a flaw. Durability varies based on sun exposure, climate and frequency of use.
