Strap for Railmaster Omega Co-Axial Master Chronometer 40 Stainless Steel / Silver / Bracelet

The lug width of the Railmaster 220.10.40.20.06.001 is 20 millimetres. This width accommodates standard 20 mm straps, easily measurable by placing a ruler between the inner shoulders of the lugs. On milanostraps.it you will find the entire collection of compatible straps in this size.

The Railmaster 220.10.40.20.06.001 responds excellently to multiple solutions. For formal wear, we recommend dark brown or black alligator, which enhances the grey-blue dial. For daily use with visible ageing, a vegetable-tanned calf in tobacco brown or burgundy tones reveals the watch's philosophy. A grey NATO strap or rubber strap with textile covering ensures sportiness without compromise.

The Railmaster uses standard removable spring bars. Purchase a lug remover tool or visit a watchmaker. Position the flat end of the tool under the pin, push upward until it disengages from the lug shoulder, then remove the old strap. Insert the new strap by aligning the holes and snap the pins into position. The operation takes just a few minutes.

Yes, any 20 millimetre strap is compatible with the Railmaster 220.10.40.20.06.001 since the lug width is standardised. The artisanal straps from milanostraps.it are made in 20 mm size and customisable for length, allowing perfect fit on any wrist. We recommend verifying the total length (measurement from lug to edge) to ensure correct extension around the wrist.

The lifespan of a leather strap depends on the material, usage and maintenance. An artisanal vegetable-tanned calf lasts 3-5 years with daily use, developing a fascinating patina. An alligator offers slightly greater longevity (4-6 years) thanks to the natural robustness of the fibre. Periodic maintenance (gentle cleaning, application of specific balms) prolongs life. Casati Milano straps include an 18-month warranty covering manufacturing defects.
