The Heritage

The Jaquet Droz Grande Seconde 39 Côtes de Genève J014014276 in white gold represents the watchmaking heritage of a manufacture founded in 1738. This 39 mm case model houses the proprietary caliber 2663 movement, certified COSC, combining hours, minutes and small seconds. The 18 mm lug width is precisely proportioned to the case diameter and dial distribution. The white gold 18-carat case ensures superior wear resistance and develops a natural patina over time. The Grande Seconde belongs to the intermediate category, suitable for various wrist sizes while maintaining visual presence.

FAQ

What is the exact lug width of the Jaquet Droz Grande Seconde J014014276?

The lug width of the Jaquet Droz Grande Seconde J014014276 is 18 millimetres. This standard was selected by the Swiss manufacture to achieve optimal proportions relative to the 39-millimetre case diameter. Always verify the measurement with a digital calliper positioned inside the lug channel before ordering an aftermarket strap.

Which type of strap pairs best with the Grande Seconde J014014276?

For the J014014276 in white gold, we recommend alligator leather in dark shades (chocolate brown or black) or natural shell cordovan. Both materials respect the formal elegance of the piece without competing visually with the dial. If you desire versatility, vegetable-tanned calf leather represents an ideal compromise between sophistication and everyday practicality.

How do you change the strap on a watch with an 18mm lug width?

To change the strap you will need a dedicated tool (spring bar remover) or a small flathead screwdriver. Remove the elastic spring bars connecting the strap to the case lugs by applying gentle pressure on one side to create leverage. Next, insert the new strap's spring bars into the lug channels until you hear a click confirming lock. The operation takes only a few minutes and can also be performed by a trusted watchmaker.

Are all 18mm straps compatible with the J014014276?

Yes, any strap with an 18-millimetre lug width is structurally compatible with the J014014276. However, aesthetic compatibility depends on your choice of material and finish: we recommend selecting high-grade leathers (alligator, cordovan, vegetable-tanned calf) that reflect the artisanal luxury spirit of the Jaquet Droz model. Avoid low-quality synthetic materials that would visually clash with the watch.

How long does a natural leather strap last on a watch?

The durability of a leather strap depends on intensity of wear, climate conditions and leather quality. Premium alligator or shell cordovan resists between 3 and 5 years with regular wear (4–5 days per week). Vegetable-tanned calf typically lasts 2–4 years. Factors that extend lifespan include: avoiding prolonged moisture exposure, periodically applying maintenance balm and rotating the strap with others to distribute wear. The ageing of leather over time is part of the inherent beauty of these natural materials.
