Strap for Tonda 39 Qualite Fleurier 10 Ans

The lug width is 18 millimetres. This measurement corresponds to the internal distance between the case lugs in rose gold and is the standard requirement for any strap compatible with this model. Always verify the measurement with a calliper before ordering a new strap.

To enhance the aesthetic of the 18k rose gold case, a cognac or dark brown alligator strap is recommended, creating chromatic continuity and amplifying the warmth of the metal. Alternatively, vegetable-tanned calf leather with structured grain offers daily-use versatility, whilst a canvas NATO strap in grey or beige generates deliberate contrast, transforming the timepiece into a more casual instrument.

The strap is replaced using a dedicated tool (spring bar remover) to remove the elastic pins (spring bars) connecting the strap to the case lugs. Position the tool between the lug and strap, apply gentle pressure to compress the internal pin, then extract the strap. Insert the new strap by aligning the holes with the pins and push until the click mechanism engages. For precision, consulting an authorised repairer is recommended.

Yes, absolutely. Any strap with an 18mm lug width is compatible with this model. High-quality artisanal aftermarket straps often offer superior finish, certified materials and customisation options compared to original straps. Always verify that the strap is supplied with standard spring bars to ensure correct alignment with the case lugs.

The lifespan of a leather strap depends on frequency of use, climatic conditions and material quality. An alligator or calf leather strap of excellent craftsmanship typically resists 3-5 years of daily use, whilst occasional use can extend the lifespan to 8-10 years. Exposure to humidity, direct sunlight and extreme temperatures accelerates ageing. Regular maintenance with balms specifically for vegetable-tanned leather significantly prolongs strap durability.
