Strap for Evidenza 19.6 Pink Gold

The lug width of the Longines Evidenza L2.175.8.53.6 is 10mm. This slim dimension is characteristic of the model and requires careful strap selection. To verify it, measure from the inside of one lug to the inside of the other using a calliper: the width must be exactly 10mm to ensure correct fit and aesthetic coherence with the tonneau case design.

For the Evidenza L2.175.8.53.6 in pink gold, brown or cognac alligator is the optimal choice: the fine, regular texture of the scales harmonises beautifully with the guilloché dial, whilst the warm patina that develops over time mirrors the natural ageing of pink gold. Alternatively, vegetable-tanned calf offers a soft feel and open grain, ensuring natural patina development and reversibility over time.

Given the delicacy of the tonneau pink gold case (19.60mm), strap replacement requires extreme care. Use purpose-designed tools: a stainless-steel spring bar tool (not brass) to prevent scratches, and work on a soft surface such as a textile mat. Position the watch with complete stability, gently engage the shoulder spring, and remove the pin with smooth movements. If inexperienced, entrust the task to a qualified watchmaker: the slim 10mm lugs do not tolerate jerky pulls or uneven pressure.

Yes, absolutely. A high-quality aftermarket 10mm strap is a recommended choice: it allows aesthetic personalisation, experimentation with materials (alligator, calf, shell cordovan) and simplified maintenance compared to the factory strap, which is often integrated. Ensure that the compatible strap has lugs precisely shaped for the tonneau case, available in specialist catalogues such as Milano Straps.

A premium leather strap with vegetable tanning, worn daily, has an estimated lifespan of 3–5 years before replacement is required. Longevity depends on factors such as frequency of wear, exposure to moisture, perspiration and maintenance treatments (periodic cleaning, conditioning with natural wax). A shell cordovan strap, being more resilient, can reach 5–7 years. Rotating multiple straps significantly extends the life of each one.
