Strap for Tonda Metropolitaine Stainless Steel / Black / Diamond

The lug width is 20mm. This measurement is calculated by measuring the external distance between the two spring bar attachment points (bayonet or screw type) in the horizontal plane parallel to the dial. Any aftermarket strap must feature exactly 20mm at the attachment zone to ensure perfect fit without mechanical play.

Alligator with vegetable tanning is the primary choice: the natural, regular grain of scutes dialogues magnificently with the geometric purity of the case. Vegetable-tanned calf leather represents an alternative that develops patina over time. A cotton-polyester NATO maintains daily versatility, while FKM rubber is ideal for aquatic or saline environments.

The Tonda PFC273-0061400-HE1421 utilises spring bar attachments. Use a dedicated removal tool: insert the flat tip into the lateral opening of the attachment, gently compress the spring until it exits the case, then remove the strap. Repeat on the opposite side. Reinstallation is identical: insert the spring bar ends into the case attachment holes with the new strap.

Yes. Any strap with a 20mm lug width is compatible: alligator, calf, fabric, rubber. MilanoStraps offers a specific collection for this width. Always verify that the strap features exactly 20mm at the attachment to prevent mechanical stress during wear.

A quality leather strap (alligator or vegetable-tanned calf) typically offers 3-5 years of moderate daily use. Wear depends on humidity exposure, perspiration, UV rays, and intensity of use. Vegetable-tanned leather naturally patinas, acquiring character. Store the watch in dry environments and clean the strap periodically with a damp cloth to extend its lifespan.
