Strap for Tradition Date Qartz 40mm

The lug width of the Montblanc Tradition 112633 is 20 mm. This measurement refers to the distance between the two spring bar attachment points on the case. It is essential to verify this dimension before purchasing a replacement strap, as straps of different sizes will not fit properly.

For the Tradition 112633, high-quality alligator straps, vegetable-tanned calf leather, or NATO straps are recommended. Alligator offers elegance and aesthetic evolution over time, calf leather guarantees a marked grain and artisanal character, whilst NATO straps provide versatility. The choice depends on intended use and dial colour (white or black).

To change the strap, you must remove the two lateral spring bars that secure the strap to the case. Use a dedicated spring bar removal tool or visit a jeweller or watchmaker. The procedure requires care to avoid scratching the case. New straps must have a 20 mm lug width to ensure compatibility.

All straps with a 20 mm lug width are compatible, regardless of brand. Milano Straps offers a selection of straps in alligator, calf leather, NATO, and rubber specifically crafted for this dimension. It is advisable to verify leather quality and construction solidity to ensure longevity and aesthetic consistency.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3–5 years under regular daily use, with proper maintenance. Longevity depends on exposure to perspiration, moisture, and UV rays. A rubber strap lasts 4–7 years. The patina that forms over time is a sign of natural ageing, not deterioration, and imparts character to the strap.
