Strap for Tradition 5.5 Stainless Steel / White / Bracelet

The lug width of the Tissot Tradition T063.409.11.018.00 is 18mm. This specification is essential for identifying compatible straps. The measurement is taken as the internal distance between the lug pins on the case. Any aftermarket strap with 18mm lug width will mount correctly to this model without modifications.

The ideal strap choice depends on intended use and personal aesthetics. For dress wear, we recommend alligator with medium grain in brown or black tones, or vegetable-tanned calf leather that will develop a natural patina over time. For daily wear, a grey or khaki NATO canvas strap provides chromatic versatility. FKM rubber is perfect for sports or water activities. Proportions matter: on a 39mm case, thinner straps maintain the watch's formal elegance.

Strap replacement requires a simple tool: a spring bar tool or small screwdriver. Place the watch on a stable surface and locate the metal pins (spring bars) securing the strap to the lugs. Press the spring bar inward gently with your tool, creating space to remove the pin. Repeat on the opposite end. The strap will come free. To install a new 18mm strap, insert the pin into the lug, position the strap, and press until it clicks into place. Avoid impacts during this operation.

Yes, absolutely. The T063.409.11.018.00 features an 18mm lug width, a standard size readily available in the aftermarket. Quality leather straps—vegetable-tanned calf, alligator, cordovan—mount without any issues. Always verify the strap width is exactly 18mm. A quality aftermarket strap often exceeds Tissot's original offering, providing customization options, colours, and materials that the OEM cannot match. MilanoStraps offers an extensive selection of artisanal 18mm straps, handcrafted in Italy to precise technical specifications.

Leather strap durability depends on material quality, tanning method, and frequency of wear. A medium-quality vegetable-tanned calf strap worn daily typically lasts 2-4 years before replacement. Alligator, being denser and more resilient leather, can last 4-6 years. FKM rubber resists degradation for 5-8 years. Critical factors include prolonged humidity exposure (sweat, rain), direct heat, and repetitive flexing. Basic maintenance—periodic cleaning with a damp cloth and rapid drying—significantly extends longevity. A leather strap is not a "forever" component; it is a consumable element that evolves with your watch.
