Frequently asked questions

What is the lug width of the Montblanc Timewalker 118488?

The Montblanc Timewalker 118488 features a lug width (ansa) of 22mm. This measurement represents the internal space between the lug terminals and is essential for selecting compatible straps. Use a digital calliper to verify this dimension by measuring the distance between the lugs.

Which strap is best suited for the Timewalker 118488?

For the TimeWalker 118488, we recommend a vegetable-tanned Tuscan leather strap in burnt brown, which dialogues elegantly with the ceramic case and develops patina over time. Alternatively, a chocolate brown alligator strap imparts formal rigour, whilst for sports contexts a water-resistant calf or structured rubber strap ensures extreme durability.

How do you change the strap on a Timewalker 118488?

Strap replacement requires: (1) position the watch case-down on a soft surface; (2) locate the spring bars at the lugs; (3) use a spring bar tool to gently compress the bar and slide off the old strap; (4) insert the new strap, aligning it correctly to the lugs; (5) ensure the spring bar returns to a stable locked position.

Are aftermarket 22mm straps compatible with the Timewalker 118488?

Yes, any strap with a 22mm lug width is compatible with the TimeWalker 118488. It is critical to verify that the width is exact: even 0.5mm variance can cause visual misalignment or abnormal pressure on the lugs. We recommend checking the technical specifications with the supplier before purchase.

What is the lifespan of a leather strap on the Timewalker 118488?

A high-quality leather strap in vegetable tanning or alligator typically lasts 3–5 years with daily wear. Longevity depends on sun exposure, humidity, frequency of wear and maintenance. Vegetable-tanned leather ages naturally, developing patina; alligator maintains colour stability longer. Periodic oiling significantly extends the strap's life.
