Strap for Grande Seconde 39 Mother of Pearl / White Gold

The lug width of the Jaquet Droz Grande Seconde J014014271 is 18 millimetres. This measurement is standard for the 39mm case and requires specific 18mm straps. To verify compatibility, measure the distance between the lugs (lateral case protrusions) with callipers: it must be exactly 18mm.

For the Grande Seconde J014014271 in white gold with Grand Feu dial, an alligator strap with vegetable tanning or a shell cordovan strap is recommended. Natural black alligator maintains formal elegance, whilst shell cordovan develops a noble patina over time. A vegetable-tanned calf leather strap with fine grain is ideal for daily wear, offering comfort and durability. Choice depends on usage context and colour preference.

Strap replacement requires removal of the spring bars (pins securing the strap to the lugs). Use a spring bar tool to press the pins laterally and release the old strap. Thread the new strap through the pin at one lug first, then align the other end and allow it to snap into place. If uncomfortable with this procedure, consult a specialist watchmaker.

Yes, any strap with 18mm lug width is compatible with the J014014271. However, we recommend choosing specialised manufacturers that respect rigorous construction tolerances: even a 0.5mm deviation can compromise fitting. Artisanal leather straps with vegetable tanning offer quality comparable to Jaquet Droz manufacturing standards.

A quality vegetable-tanned leather strap lasts approximately 5-7 years with daily wear, accounting for natural fibre degradation. Alligator and shell cordovan are more durable (7-10 years). Longevity depends on usage frequency, climatic conditions and maintenance: a cared-for leather strap (cleaned periodically, dried if wet) develops noble patina rather than deteriorating.
