Strap for Grande Seconde 39 Mother of Pearl Diamond / White Gold

The lug width of the Jaquet Droz Grande Seconde J014014272 is 19mm. This measurement defines strap compatibility: it must be measured from the inner edge of the left lug to the inner edge of the right lug. An incorrectly sized strap would generate tension on the attachment system and damage the case.

For the Grande Seconde J014014272 in white gold, alligator leather with vegetable tanning represents the most appropriate choice: the granular texture dialogues beautifully with the brushed case finish. Alternatively, vegetable-tanned calf leather provides daily versatility and develops an elegant patina over time. For sports contexts, nylon NATO straps are viable; for aquatic environments, FKM rubber is ideal.

To change a 19mm lug width strap: remove the watch and place it on a soft surface (felt). Locate the horizontal spring bars connecting the lugs to the strap. Using a spring bar tool, depress the pin and slide the strap out. Insert the new strap in the same position, ensuring the spring bar clicks securely into the lug hole.

Yes, an aftermarket 19mm strap is fully compatible with the J014014272. Milano Straps offers a comprehensive range of 19mm straps in various materials (alligator, calf, shell cordovan, NATO, rubber) designed specifically for this lug width. Compatibility is guaranteed by standardised dimensions.

The lifespan of a natural leather strap depends on usage and maintenance. A quality alligator or calf strap with vegetable tanning can last 3-7 years with regular wear. Ageing accelerates with perspiration, moisture, and sun exposure. The patina that develops is desirable, but when the strap shows deep cracks or structural loss, replacement is necessary. Periodic conditioning with natural oils (mink oil) extends longevity.
