Strap for Banana Centenary Edition Stainless Steel / Silver

The lug width of the Tissot Heritage T117.509.16.032.00 is 20 millimetres. This measurement represents the distance between the two casings' terminals where the strap is attached. It is essential to verify this specification before purchasing an aftermarket strap to ensure perfect compatibility and installation without forcing.

For a 27mm Heritage in brushed stainless steel, alligator leather with vegetable tanning represents the most elegant choice: the irregular grain pattern pairs perfectly with the case's satin finish. Alternatively, Hermès calf or Fjord calf offer visible ageing and patina development with wear. For informal environments, cotton-polyester NATO straps guarantee stylistic authenticity without compromise.

Use a spring bar tool or equivalent instrument to gently lift the case terminals. Insert the tool's tip into the hole on each side of the case, compress the internal spring, and slide the old strap outward. Insert the new strap, aligning it with the terminals, and allow the spring to reposition itself. Avoid forcing: a 20mm lug width is compact and requires precision, not force.

Yes, provided they are certified for 20 millimetre lug width. Milano Straps supplies handcrafted leather, NATO, and rubber straps specific to this width. Quality varies significantly between manufacturers: straps constructed with straight ends guarantee impeccable fit, whilst curved ends require greater geometric precision to suit this compact case.

A high-quality leather strap (alligator, Hermès calf, or shell cordovan) typically lasts 3-5 years with daily wear, depending on climate, frequency of use, and care. Vegetable-tanned leather ages visibly and develops patina: this is a virtue, not a defect. Protect from excessive moisture and direct sunlight. A Fjord calf strap, if well maintained, can last up to 7 years; alligator tends to remain more unchanged over time due to the natural structure of the scale.
