Strap for Novonaut N-42 Cobalt Blue Edition / Block Bracelet

The Fortis Novonaut F2040012 features a lug width of 22 millimetres. This dimension is the standard for 42mm watches designed for daily and professional use. Always verify the lug width before ordering an aftermarket strap, by measuring the internal space between the case lugs or consulting the factory documentation.

The choice depends on intended use. For professional and formal contexts, we recommend a vegetable-tanned leather in dark tobacco brown, offering both elegance and durability. For outdoor activities, a NATO strap in steel grey or navy blue maintains the chronograph's tactical vocation. For humid environments or light diving, a butadiene rubber strap delivers reliability without compromise.

Remove the watch from your wrist. Locate the lugs (small metal cylinders) on the sides of the case. Use a spring bar removal tool or fine file to gently push the pin from one side to the other, sliding it out of the attachment. Once the pin is removed, the old strap will detach. Insert the new strap by aligning the lateral holes, then reinsert the pin until it locks firmly in place.

Any strap with a 22-millimetre lug width is compatible with the Novonaut F2040012. On milanostraps.it you will find a curated selection of straps in vegetable-tanned leather, alligator, NATO and rubber, all tested to fit perfectly within this lug width. Always verify dimensions before purchase to avoid incompatibility.

A quality leather strap, processed with vegetable tanning, lasts on average 4 to 7 years with moderate daily use, developing an attractive patina over time. Durability depends on UV exposure, ambient humidity and frequency of wear. Well-maintained leather, regularly cleaned and protected from extreme conditions, ages beautifully and can achieve 10 to 12 years of useful life.
