Strap for Grande Seconde 39 Black Enamel / White Gold

The lug width of the J014014214 is 19 millimetres. This measurement was selected by Jaquet Droz to maintain the proportional balance between the 39 mm case and the wrist. The 19 mm standard is widely compatible with artisanal straps available on the market, allowing diverse colour and material choices without constructive compromises.

For a J014014214 in white gold, we recommend an alligator strap crafted with vegetable tanning. The natural grain of the leather pairs elegantly with the chromatic neutrality of white gold, creating aesthetic unity. Alternatively, European vegetable-tanned calf leather develops characteristic patina over time, amplifying artisanal character. For sportier approaches, military-canvas NATO straps emphasise the formal rigour of the spherical-concentric composition.

To change the strap on a J014014214, you must remove the spring bars that connect the strap to the case. Use a spring bar tool to gently disengage the bars from underneath. Remove the previous strap and insert the new one, ensuring the spring bars sit correctly in their designated seats on the lug. Verify the strap is symmetrical and the lug fully covers the bars. A specialist atelier completes the operation within minutes.

Yes, any strap with an exact 19 millimetre lug width is compatible with the J014014214, provided the thickness does not obstruct the case lug. We recommend artisanal straps manufactured in vegetable tanning or technical rubber, guaranteeing durability and natural patina development over time. Always verify that the strap does not create friction with the lug edges, especially during initial wear.

A natural leather strap subjected to regular wear typically lasts 3-5 years before requiring replacement or repair. Durability depends on water exposure, perspiration, and friction patterns at the wrist. Vegetable tanning, being more robust, extends service life to 7 years. Gradual and uniform patina is a sign of desirable natural ageing. A specialist atelier can extend strap life through re-stitching or reinforcement of edges.
