Strap for Khaki Field Automatic Stainless Steel / Beige

The H70555523 features a 22mm lug width. This measurement refers to the space between the lugs (case horns) where the strap connects. It is essential to verify that any aftermarket strap is precisely 22mm to ensure a perfect fit without lateral play or unsightly gaps.

The choice depends on intended use and aesthetic preference. To preserve its military-functional heritage, a robust NATO strap or vulcanised rubber remain authentic options. For refined daily wear, calf leather with vegetable tanning in brown or cognac tones harmonises beautifully with the khaki dial. A high-quality alligator strap adds discrete luxury and exceptional durability.

Remove the original strap by extracting the spring bars that connect the lugs to the case. Gently angle each spring bar outward to compress the internal spring, then pull steadily until the bar disengages from its seat. Install the new strap by inserting the spring bar through the first lug, compressing the spring, and securing the bar in the opposite lug. Ensure the strap is properly aligned with no play.

Yes, provided they strictly meet the 22mm lug width specification. Artisanal-quality straps in leather, NATO, rubber, or even shell cordovan are fully compatible. The critical factor is verifying exact width—even 0.5mm deviation can compromise fit. Always consult the manufacturer's specifications before purchase.

A quality leather strap (calf, alligator, cordovan) subjected to moderate daily use maintains structural integrity for 3–5 years. Vegetable-tanned leather develops an appealing patina over time. To extend durability, avoid prolonged saltwater exposure, apply periodic maintenance (gentle cleaning and conditioning), and rotate between multiple straps if feasible. Alligator, being more resistant, can exceed a decade of service life.
