Frequently asked questions

What is the lug width of the Jaquet Droz Grande Seconde J006030240?

The Jaquet Droz Grande Seconde J006030240 features an 18-millimetre lug width. This dimension is measured from one lug hole to the other, perpendicular to the case. Verifying this measurement is essential before purchasing an aftermarket strap.

What is the best strap for the Jaquet Droz Grande Seconde J006030240?

Genuine alligator with vegetable tanning is the most aesthetically coherent choice, as it complements the dial's compositional simplicity and develops a beautiful patina over time. However, vegetable-tanned calf offers reliable daily comfort, whilst canvas NATO straps provide a more pragmatic interpretation of the watch.

How do I change the strap on the Jaquet Droz Grande Seconde?

The Grande Seconde employs quick-release spring bars. Place the watch on a soft surface, locate the small lever beneath each lug seat, gently press downward, and withdraw the pin. Insert the new strap in the same direction, ensuring the spring bar clicks into place. If you encounter difficulty, contact Casati Milano atelier for assistance.

Is an 18mm aftermarket strap compatible with the Jaquet Droz Grande Seconde J006030240?

Yes, any strap with an 18mm lug width is compatible with the Grande Seconde. Milano Straps offers an extensive selection of artisanal straps in this specification, each inspected by hand before dispatch.

How long does a leather strap last on the Jaquet Droz Grande Seconde?

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3-5 years of daily wear, depending on frequency of use and maintenance. Exposure to moisture and perspiration reduces lifespan; rotating multiple straps extends the longevity of each. Milano Straps offers restoration services and stitch replacement to prolong strap life.
