FAQ
What is the exact lug width of the Omega Railmaster 2812.52.31?
The lug width of the Railmaster 2812.52.31 is 21 mm. This is an atypical, non-standard measurement that requires straps specifically constructed for this dimension. It is important to verify compatibility before purchasing an aftermarket strap.
What is the best strap material for the Omega Railmaster 2812.52.31?
The best material depends on usage: black or brown alligator for formal elegance and maximum durability; vegetable-tanned calf leather for fascinating natural aging; NATO fabric for sporting versatility. The stainless steel case of the Railmaster pairs excellently with all these materials.
How do I change the strap on my Omega Railmaster 2812.52.31?

Yes, provided the lug width is exactly 21 mm, measured internally between the edges. The straps available on milanostraps.it for this measurement have been tested for compatibility with the Railmaster and similar stainless steel models.
How long does a leather strap last on the Railmaster 2812.52.31?
A quality leather strap (alligator or vegetable-tanned calf leather) lasts on average 3-5 years of moderate daily use, depending on care and moisture exposure. Casati Milano guarantees 18 months on all made-to-measure straps, with the possibility of leather renewal.
