Strap for Couturier Quartz Chronograph Black / Strap

The lug width of the Tissot Couturier T035.617.16.051.00 is 23mm. This dimension is measured as the internal distance between the lug ends, from shoulder to shoulder of the strap seat. It is important not to confuse this measurement with the case width: the 23mm represents exclusively the available space between the attachment points and requires millimetre precision when selecting a strap.

For the Couturier T035.617.16.051.00, we recommend an alligator strap of first quality for formal-elegant use, or calf leather with vegetable tanning for a versatile solution that ages naturally over time. A 6-ring NATO in textured weave maintains the chronograph's sporting heritage, whilst FKM rubber with brushed finish offers maximum performance in humid environments. Your choice depends on the dial type: on black dials, opt for cognac brown; on silver/ivory grounds, medium chestnut creates balance; on dark blue, navy alligator enhances the colour scheme.

Strap replacement is accomplished using a spring bar tool or tweezers. Position the watch on a stable surface, gently press the internal spring mechanism anchor inside the lug, and slide the spring bar out of the mounting holes. Repeat on the opposite lug. Next, align the new strap, insert the spring bar into the case holes, and ensure the spring clicks correctly into the retention holes. For optimal installation on a 23mm lug, we recommend professional assistance if you are unfamiliar with the procedure.

Yes, the Couturier T035.617.16.051.00 accepts high-quality aftermarket straps in 23mm sizes. Our collection features handcrafted alligator, vegetable-tanned calf, NATO military, and FKM rubber options. All our straps are produced to measure at the Casati Milano Atelier and guarantee full compatibility with standard 1.5mm or 1.8mm spring bars. We always verify your watch's spring bar width before recommending a choice.

The lifespan of a leather strap depends on usage intensity and construction quality. A handcrafted strap in first-quality alligator or vegetable-tanned calf typically lasts 3-5 years with regular use (3-4 days per week). Vegetable-tanned leather develops a natural patina that extends functional life, though surface creasing may appear. A 6-ring NATO in synthetic textile resists longer (5-7 years), whilst FKM rubber retains elasticity for 4-6 years. The determining factor remains maintenance: avoid unnecessary prolonged water exposure, clean regularly with a soft brush, and store in a dry environment.
