Strap for Chronograph Automatic

The lug width of the Montblanc Nicolas Rieussec 102336 is 20 millimetres. This measurement is critical for strap compatibility and is calculated by measuring the distance between the two case lugs. A digital calliper allows you to verify it accurately by positioning the tip between the centre of one lug and the other.

Alligator leather in vegetable tanning is the choice most coherent with the haute horlogerie spirit of the 102336: the geometric grain of the leather creates a harmonious dialogue with the purity of the stainless steel case. Vegetable-tanned calf is a more restrained alternative for formal contexts, whilst cotton-mercerised NATO is ideal for sporty use. Fluoroelastomeric rubber, finally, is the most functional solution for aquatic environments.

Position the watch on a soft surface with the case facing downwards. Use a spring bar tool to compress the internal springs of the lugs. Insert the tip of the tool under the lug from one side, press gently until the spring is released, then extract the lug. Repeat from the other side. To install the new strap, align the strap lugs on the case lugs and reinsert the spring bars by compressing the springs until a click locking sound is heard.

Yes, any strap with a 20-millimetre lug width is compatible with the 102336. High-quality aftermarket straps—made from alligator, calf or technical materials—often offer superior value for money compared to original Montblanc straps, whilst maintaining full mechanical and aesthetic compatibility.

The longevity of a leather strap depends on frequency of wear and maintenance. An alligator or calf strap, worn daily, has an average lifespan of 5 to 8 years before requiring replacement. Vegetable tanning develops a natural patina over time, creating character creases that enrich the aesthetic. Regular cleaning with a damp cloth and rapid drying significantly extend durability.
