Strap for Tonda Metropolitaine Stainless Steel / Green / Diamond / Bracelet

The lug width is 18 mm. This measurement should be taken from the inner edge of the right lug to the inner edge of the left lug, excluding the curvature. This specific dimension is critical for maintaining the harmonious proportions for which the Tonda was designed.

For a watch with such calibrated proportions, we recommend black or dark brown alligator, which amplifies formal sobriety. Alternatively, vegetable-tanned cognac-coloured calf leather introduces warmth while maintaining elegance. A cotton NATO in grey or dark blue also offers versatility for less formal environments.

The strap is changed by removing the spring bars that connect the lugs to the case. Obtain a spring bar tool: insert the flat tip beneath the pin, apply downward pressure to release the spring, and extract the pin. Repeat on the opposite side. Position the new strap and reinsert the pins, ensuring they click securely into the case slots.

Yes, provided the lug width is 18 mm. Milano Straps offers a broad selection of bespoke-crafted straps compatible in leather, NATO, and rubber. Verify that the passants are sufficiently spacious to accommodate the 18 mm lug without excessive compression.

A quality alligator or calf strap, with periodic maintenance (cleaning and light conditioning), typically lasts 4–7 years. Longevity depends on frequency of wear, humidity exposure, and tanning method. Vegetable-tanned straps age magnificently, developing a patina that enhances their aesthetic value over time.
