Strap for Tradition Automatic Small Second Bicolor / Silver / Bracelet

The lug width is 20 millimetres. To verify compatibility, measure with callipers the perpendicular distance between the two metal lugs of your watch: the result must be 20.00 ± 0.5 millimetres. This tolerance is standard in watchmaking because handcrafted straps may present minor variations due to manual finishing. A strap with lug width exceeding 20.5 millimetres will force insertion; one below 19.5 millimetres will exhibit pendular movement during wear.

The Tradition T063.428.22.038.00 pairs excellently with multiple strap types. American alligator represents maximum formality with superior longevity (8–12 years). Italian or French calf leather (Hermès standard) develops personal patina over time. NATO straps in polyamide canvas are ideal for humid or dusty environments, with instant drying properties. FKM rubber vulcanised at low temperature offers modernity whilst maintaining classical elegance. Selection depends on usage context and personal aesthetic preference.

Strap change is a straightforward operation requiring a spring bar tool. Position the watch on a soft cotton cloth surface. Insert the small hook of the spring bar tool into the spring bar slot on one side, pulling slightly downward until the metal lug releases from its hole. Repeat on the opposite side; the strap will then detach. To install the new strap, align the holes with the lugs and press the spring bar until it locks on both sides. If unfamiliar with the procedure, a watchmaker can complete this in five minutes at minimal cost.

Yes, absolutely. Any strap with 20 millimetre lug width is compatible with the Tradition T063.428.22.038.00. High-quality artisanal leather, vegetable-tanned calf, alligator, shell cordovan, NATO, and FKM rubber straps offer superior aesthetic alternatives to standard issue straps. Purchase from specialised producers guaranteeing precision tolerances, as handcrafted straps from non-certified sources may present dimensional variations.

Lifespan depends on leather quality and maintenance. A vegetable-tanned alligator strap lasts 8–12 years with ordinary use and basic maintenance (periodic cloth cleaning, rapid drying if rain-exposed). A superior quality calf strap lasts 5–8 years. A NATO strap in polyamide lasts 3–5 years. Longevity increases significantly with preventive maintenance: periodic hydration with natural oils, protection from prolonged sun exposure, immediate drying after saltwater contact. FKM rubber straps have virtually indefinite lifespan (10+ years) as they are not subject to biological degradation.
