Strap for Couturier Automatic Ladies Two Tone

The lug width of the Tissot Couturier T035.207.22.011.00 is precisely 18 millimetres. This measurement is obtained by positioning a digital calliper or ruler between the inner shoulders of the lugs (the contact point with the strap). It is a precise constructive dimension: straps of 20 or 22 millimetres are not compatible and will not fit on the case.

The Tissot Couturier T035.207.22.011.00 pairs ideally with alligator straps of elevated quality (pronounced grain), vegetable-tanned calf leather (which develops patina over time), or robust NATO straps in durable fabric. For sports-oriented contexts or humid environments, FKM (Viton) rubber ensures longevity and easy maintenance. Choice depends on daily usage and desired aesthetic.

Strap replacement requires a spring bar tool (U-shaped implement with Teflon-coated tips). Position the tool within the lateral grooves of the lugs, apply gentle pressure to compress the internal springs, and extract the previous strap. Insert the new strap by aligning its pins with the case shoulders, release pressure, and verify secure attachment. If you lack the specialised tool, a professional watchmaker will complete the operation within minutes.

Yes, aftermarket straps compatible with 18mm lug width are available through specialised suppliers such as milanostraps.it. Selection includes leather, NATO, rubber, and synthetic materials. It is essential to verify the specific «18mm» designation at purchase, as this dimension is less prevalent than standard 20 or 22 millimetre widths. Do not force straps of different widths: this would compromise the mechanical integrity of the case.

Lifespan of a leather strap depends on material quality and usage patterns. A premium-grade alligator or vegetable-tanned calf strap typically endures 3–5 years of daily wear. Natural patina development and visible wear are desirable characteristics, not defects. Environmental factors such as humidity, prolonged solar exposure, and perspiration reduce longevity. Periodic maintenance—cleaning and treatment with natural wax—significantly extends strap lifespan.
