Frequently asked questions

What lug width does the Montblanc Timewalker 112604 feature?

The Montblanc Timewalker 112604 is equipped with a 22mm lug width. This measurement is compatible with an extensive selection of artisanal straps, enabling aesthetic customisation without functional compromise. A 22mm lug width is standard across many sports chronographs and provides excellent versatility in available materials.

What is the best strap for the Montblanc Timewalker 112604?

Selection depends on intended use and personal aesthetic preference. For formal occasions, we recommend vegetable-tanned Tuscan leather in moka or dark brown tones, which emphasises the contrast with the ceramic and steel case. For sports or casual wear, a NATO textile strap in charcoal grey or vulcanised rubber offers resilience and practicality. For business contexts, smooth calf leather with a brushed steel deployante buckle ensures understated elegance and longevity.

How do I change the strap on the Montblanc Timewalker 112604?

Strap replacement requires a dedicated spring bar removal tool. Position the watch on a soft surface with the caseback facing upwards, locate the small hole on each side of the case at the lug attachment point, insert the tool into the aperture and gently push the spring bar until it retracts into its housing, then remove the previous strap. Insert the spring bars of the new strap into the housings and allow them to click into position. This procedure demands precision to avoid scratching the case.

Is an aftermarket strap compatible with the 112604?

Yes, any strap with a 22mm lug width is compatible with the Montblanc Timewalker 112604. Artisanal straps from Milano Straps, crafted from Tuscan leather, vegetable-tanned hide, NATO fabric and rubber, fit perfectly due to international standardisation of lug dimensions. The construction quality of an artisanal strap can genuinely elevate the overall user experience compared to factory-supplied straps.

What is the durability of a leather strap for this watch?

A Tuscan leather strap with vegetable tanning, such as those offered for the 112604, provides durability of 3 to 5 years under daily use and regular maintenance. Longevity depends on exposure to sunlight, humidity and proper storage practices. The subtle patina that develops over time is a desirable characteristic of vegetable-tanned leather, signalling material authenticity. To extend strap lifespan, we recommend periodic cleaning with a damp cloth and natural air-drying, avoiding direct heat sources.
