Frequently asked questions

What is the lug width of the Longines La Grande Classique L4.709.2.12.2?

The lug width of the Longines La Grande Classique L4.709.2.12.2 is 18 millimetres. This measurement is the fundamental parameter for selecting a compatible strap. It is measured as the distance between the two lugs that anchor the strap to the case. Always ensure compatibility before purchasing an aftermarket strap.

What is the best strap for the Longines La Grande Classique L4.709.2.12.2?

The best strap depends on your intended use. For formal elegance, an alligator strap with vegetable tanning offers noble aesthetics and natural patina development. For daily wear, smooth calfskin with vegetable tanning provides versatility and durability. A shell cordovan strap allows appreciation of the leather's unique reflections. Your choice should consider the context of use and your personal preference regarding the patina you wish to develop over time.

How do I change the strap on my Longines La Grande Classique L4.709.2.12.2?

Strap change occurs through extraction of the spring bars that connect the strap to the case lugs. You must use a dedicated tool (strap removal tool or manual opener) to compress the internal spring of the pin and slide it out. Subsequently, insert the new strap by aligning it with the lugs and sliding the pin back into position. If you do not possess the appropriate tool, it is advisable to consult a professional watchmaker or our Casati Milano atelier.

Can I use an aftermarket strap compatible with my Longines La Grande Classique L4.709.2.12.2?

Yes, absolutely. The Longines L4.709.2.12.2 accepts any strap manufactured for the 18-millimetre lug width. Artisan aftermarket straps from milanostraps.it are specifically created for this measurement, guaranteeing perfect compatibility. It is important to verify that the strap is indeed 18mm and that construction quality is high to ensure durability and aesthetics.

How long does a leather strap last on the Longines La Grande Classique L4.709.2.12.2?

The lifespan of a leather strap depends on the material, tanning method, and usage. An artisan-quality strap with vegetable tanning, such as those from milanostraps.it, guarantees a lifespan of 3-5 years with daily use. The patina that develops over time testifies to the leather's authenticity and natural wear characteristics. With proper maintenance and rotation with other straps, longevity can extend further. The Casati Milano atelier provides an 18-month warranty on all custom-made straps.
