Strap for TimeWalker Date Automatic 39 Silver / Red Gold Numerals

The Montblanc Timewalker 110340 features a lug width of 20 millimetres. This is the standard distance between the lugs of the case and is essential for selecting a compatible strap. To verify your measurement, use a digital calliper positioned perpendicularly to the lugs, measuring from the inner edge of the upper lug to the inner edge of the lower lug.

Your choice depends on intended use. For formal settings, a black or dark brown alligator leather with vegetable tanning emphasises the German precision of the movement. For daily versatility, a NATO in grey or navy blue renders it casual whilst retaining credibility. Those wearing it during intensive travel benefit from an FKM rubber in grey-blue tone, fully water-resistant and ergonomic. Cognac calf leather represents the compromise: elegant, naturally patinatable, and unpretentious.

Use a spring bar remover tool to extract the elastic pins anchoring the strap to the lugs. Insert the flat tip of the tool gently beneath the spring bar, press inward to compress the spring and pull simultaneously. Repeat for both sides. Insert the new strap by aligning its holes with the pins, ensuring the strap sits flush without lateral play.

Yes, completely. Any strap constructed for a 20-millimetre lug width mounts without issue. Compatibility is not brand-dependent but strictly a matter of width. A hand-crafted leather strap manufactured to watch-grade standards for 20mm often offers superior construction to standard OEM straps and infinitely greater aesthetic customisation.

A quality leather strap, properly maintained, resists 3–5 years of moderate daily use. The critical variable is moisture exposure: perspiration, rain and showers accelerate deterioration. Shield your strap from prolonged immersion, dry it gently if wet, and occasionally apply a vegetable balm. A vegetable-tanned strap develops characteristic patina within the first months, a sign of material authenticity. When your strap begins showing visible cracks or weakened stitching, replacement is warranted.
