Strap for Bellissima Small Lady Stainless Steel / Silver / M Double Tour

The lug width of the Tissot Bellissima T126.010.16.113.01 is 4mm. This specific measurement represents the width of the slot between the two lugs of the case and is the fundamental parameter for selecting a compatible strap. To measure correctly, position a digital calliper perpendicularly between the inner edges of the lugs at the midpoint. Do not confuse lug width with lug-to-lug distance (which on the Bellissima is approximately 24mm).

The best strap depends on usage and aesthetic preferences. For formal occasions, we recommend natural alligator with vegetable tanning in dark brown (moka, teak) or aged cognac: the marked grain and patina create elegant contrast with the steel. For daily wear, vegetable-tanned calf leather in grey or black matte ensures solidity and versatility. For a versatile and unpretentious approach, polyamide NATO in grey, navy blue or beige offers quick-change practicality. FKM rubber represents the choice for those who refuse climate compromises.

Strap changing requires minimal precision. Obtain two replacement pins of 4mm (available at Tissot service centres or specialised retailers) and a spring bar removal tool. Invert the watch and, with the tool, push the small metal hook towards the centre of the case to open the original strap spring; extract the pin. Repeat on the other lug. Insert the new pins into the case holes, ensuring the springs snap into place with a distinct click. Verify that the strap is stable and not loose. If inexperienced, entrust the task to a certified watchmaker to avoid damage to the steel lugs.

Yes, the Bellissima is fully compatible with any aftermarket 4mm-width strap of adequate length for your wrist. The case has no proprietary constraints on attachments: artisanal straps in alligator, vegetable-tanned calf, polyamide NATO, FKM rubber and leather from specialised suppliers will insert without forcing. It is essential to verify the total strap length (typically 75–80mm for the upper end and 110–120mm for the lower on a 26mm case) to ensure ergonomic wrapping around the wrist. Non-certified 4mm straps may not fit or cause aesthetic issues.

Leather strap lifespan depends on tanning, thickness, usage and climate conditions. A quality alligator or vegetable-tanned calf strap lasts an average of 3–5 years with daily wear, developing pleasant patina. With occasional use (2–3 times per week), duration extends to 5–7 years. Chemically retanned leather (chrome tanning) withstands up to 2–3 years in extreme conditions. Longevity increases if you protect the strap from direct sun exposure, excessive humidity and clean it periodically with a soft cloth. The metal buckle (if present) undergoes inevitable aesthetic ageing but does not compromise functionality.
