Strap for Tradition 5.5 Stainless Steel / White / Strap

The Tissot Tradition T063.409.16.018.00 features an 18-millimetre lug width. This measurement represents the internal distance between the passing lugs that connect the strap to the watch case. It is a consolidated standard in the classical watchmaking segment, compatible with most high-end artisanal straps.

For the Tradition T063.409.16.018.00, a brown calf leather strap with vegetable tanning is the most harmonious choice: the patina that develops over time mirrors the ageing of the case's brushed stainless steel. Alternatively, a wine-coloured shell cordovan or a black alligator strap creates elegant contrast whilst maintaining formal gravitas. For casual wear, a heavyweight NATO strap functions without aesthetic compromise.

The Tradition T063.409.16.018.00 utilises standard 18mm passing lugs. To change the strap, position the watch on a stable surface, locate the side pins, and use a specialised tool (pin remover) to push them outward. Some pins are removable from one side only; others pass completely through: check the specific case construction. Insert the new pins into the replacement strap and secure them firmly in the case. If unfamiliar with the procedure, consult an expert watchmaker to avoid damage to the lugs.

All straps with an 18mm lug width are mechanically compatible. However, the strap's height and thickness must respect the case geometry: the lug profile and curvature require careful evaluation. High-quality straps featuring vegetable tanning, shell cordovan, alligator, vulcanised rubber, and heavyweight NATO fabrics ensure proper fit and longevity. MilanoStraps offers a curated selection of 18mm straps specifically tested for classical watches of this proportion.

A quality artisanal leather strap (calf, cordovan, alligator) typically lasts 3–5 years with moderate daily use, depending on climate (humidity, temperature), frequency of wear, and maintenance. Vegetable-tanned leather tends to outlast chrome-tanned alternatives. The leather continuously flexes at the lug contact points, generating natural wear. NATO and rubber straps have similar lifespans but tolerate extreme conditions (perspiration, water, dust) better. Periodic maintenance—cleaning with a soft cloth and conditioning with specific oils—extends strap longevity.
