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

The lug width of the Railmaster 220.12.40.20.06.001 is exactly 20 mm. This dimension represents the distance between the two case lugs where the strap is attached. It is important to measure from the inner face of one lug to the other to verify the compatibility of an aftermarket strap.

The Railmaster pairs perfectly with alligator straps featuring vegetable tanning, which acquire a noble patina over time, or in honey or cognac calf leather for a warmer touch. For sports use, a grey textile NATO strap maintains the tool watch vocation. A structured FKM rubber is ideal for water use thanks to its resistance to moisture and UV rays.

Strap replacement requires a spring bar removal tool. Position the watch horizontally, insert the tool tip under the spring bar of one lug, press gently upward until the spring is released, then extract the old strap. Repeat for the other lug and install the new strap by aligning the holes with the spring bars.

All straps with a 20 mm lug width are compatible with the 220.12.40.20.06.001. Always verify the width by measuring from the inner face of one lug to the other. On milanostraps.it you will find a selection of 20 mm straps customizable in leather, color and stitching thread.

A quality leather strap, such as alligator or vegetable-tanned calf, lasts an average of 3-5 years with daily use, depending on frequency of use, exposure to sweat and humidity, and maintenance. Casati Milano artisanal straps include an 18-month warranty and can be restored by specialized professionals.
