Strap for Grande Seconde 39 Mother of Pearl / Red Gold

The lug width (ansa width) of the Grande Seconde J014013228 is 18mm. This dimension represents the distance between the pins that attach the strap to the case lugs. Always verify this measurement before purchasing an aftermarket strap: an incorrect size will not fit properly.

For the Grande Seconde in red gold, we recommend an alligator strap in dark brown or vegetable-tanned calf leather. Both materials create elegant visual contrast with the red gold and develop natural patina over time, complementing the metal's ageing. For maximum durability, shell cordovan represents the absolute benchmark.

To change the strap, you will need a spring bar removal tool. Gently insert the tool under the pin attaching the strap to the lug, apply leverage to compress the internal spring, and extract the pin. Repeat on the other side. Ensure the pins are fully retracted before inserting the new strap. This operation requires care: if you are inexperienced, consult a professional watchmaker.

An aftermarket strap is compatible if it has a lug width of exactly 18mm. Verify that the strap's passant is appropriately sized for the case width (39mm diameter implies specific proportions). Artisanal straps of superior quality, custom-made with premium leather and precious metal hardware, offer guaranteed compatibility and superior longevity compared to industrial options.

A high-quality natural leather strap (alligator, vegetable-tanned calf, shell cordovan) lasts between 5 and 10 years with daily wear, depending on wearing frequency, ambient humidity, and maintenance care. Vegetable-tanned leather tends to last longer than industrially tanned alternatives. Regularly applying silicone protectant and storing the watch in dry environments significantly extends strap lifespan.
