Strap for Railroad 46 Chrono PVD / Black

The lug width of the Hamilton Railroad H40686335 is 22 millimetres. This measurement is taken from the centre of the left attachment hole to the centre of the right attachment hole on the case. Verifying this measurement with a digital calliper before ordering a strap is essential to avoid compatibility issues.

For this robust 46mm case, we recommend quality leather straps: alligator with vegetable tanning for an authentic grainy texture, or shell cordovan for superior patina development. If you prefer practicality, a premium NATO strap in regenerated yarn resists daily impacts. For military or aquatic environments, Cordura rubber offers maximum durability. All are available for <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-22mm">22mm compatible straps</a>.

Obtain a spring bar remover tool. Position the thinner end of the tool into the small lateral hole of the metal lug, pushing downward to compress the spring. The lug will retract and the old strap will loosen. Repeat on the opposite side. To fit the new strap, align the holes with the lugs and apply gentle pressure until you hear a click. Professional fitting is recommended through Casati Milano for maximum security.

Yes, provided the strap is certified for 22mm lug width. Milano Straps artisanal straps are constructed to 22mm specifications: brushed stainless steel hardware, reinforced passants, finishes consistent with the Railroad model's technical language. A well-constructed aftermarket strap often outperforms the original rubber or textile strap in durability.

A quality leather strap (alligator or shell cordovan) with proper maintenance lasts 3–5 years with daily wear. The internal side wear (friction against wrist skin) determines longevity more than the external surface. Applying conditioner cream every six months slows ageing. A NATO strap, lacking elastic adhesive, lasts beyond 7 years. Cordura rubber withstands over 10 years if protected from prolonged UV exposure.
