Strap for Tradition 5.5 Lady 31 Stainless Steel / Silver

The lug width of the Tissot Tradition T063.209.16.038.00 is precisely 14 millimetres. This specification is unique to the 31mm case model and requires straps specifically constructed to this measurement. To measure correctly, place a ruler from the centre of one lug to the inside of the other, perpendicular to the case, excluding the depth of the slot.

The ideal strap depends on the intended context. For formal and office environments, we recommend authentic alligator in black or vegetable-tanned calfskin in deep tones (brown, cognac). For daily versatility, calfskin in tobacco or cream allows transitions between formal and casual wear. During warmer months, a NATO in grosgrain or canvas—grey or taupe—provides practicality without compromising the dress aesthetic.

Replace the strap using a spring bar removal tool. Position the watch on a soft surface with the strap facing upward. Gently insert the tool into the small slot adjacent to the spring bar, compress the internal spring and slide the strap outward. Repeat on the opposite side. For installation of the new strap, align the holes with the springs and push firmly until you hear or feel the click.

Aftermarket straps at 14 millimetres manufactured by specialist ateliers offer superior quality compared to original equipment. We recommend vegetable-tanned calfskin, authentic alligator, or shell cordovan for premium applications. These materials develop natural patina with time, enhancing the watch's aesthetic. Always verify that the strap is constructed to the 14mm specification to ensure perfect compatibility.

A quality artisanal leather strap—calfskin, alligator or shell cordovan—typically lasts between 3 and 5 years with regular maintenance and daily wear. Longevity depends on humidity exposure, frequency of use and care applied. Keep the strap dry, avoid prolonged direct sunlight and occasionally apply a specialist leather balm. Shell cordovan and alligator tend to outlast standard calfskin.
