Strap for Heritage Banana Naoko Tsuji

The lug width of the Tissot Heritage T117.509.36.052.01 is 20 millimetres. This measurement represents the exact width between the two spring bars that connect the strap to the case. When purchasing a replacement strap, it is essential to verify compatibility with this specific dimension.

The optimal strap choice depends on intended use. For formal contexts, alligator or vegetable-tanned calf leather enhance the case's geometric purity. For versatile daily wear, soft calf leather provides comfort and durability. For a casual-sporty aesthetic, NATO straps in fabric or canvas emphasise the model's proportional simplicity.

Strap replacement requires a spring bar tool. Position the tool in the small lateral groove of one spring bar, apply gentle inward pressure to compress the spring, and extract the bar from the case. Repeat for the second bar. Insert the bars into the new strap following the reverse procedure, ensuring they remain firmly seated.

Yes, provided the lug width is precisely 20mm. Quality aftermarket straps employ the same spring bar attachment systems as originals. The critical factor is accurate measurement and selecting suppliers who guarantee precision tolerances to avoid mounting instability or movement.

Leather strap durability varies with usage frequency and material quality. An alligator or vegetable-tanned calf strap, when properly maintained, withstands 3–5 years of daily wear. Natural leather ageing is part of its appeal, though the lug area (maximum stress point) eventually requires replacement. Moisture and perspiration exposure accelerates degradation; regular conditioning with appropriate creams extends lifespan significantly.
