Frequently asked questions

What is the lug width of the FP Journe Souveraine 1499.3 CAR 40 RG GR?

The lug width of the FP Journe Souveraine 1499.3 CAR 40 RG GR measures exactly 18 mm. This dimension is critical for strap compatibility: an 18 mm lug width requires straps of identical width to ensure a perfect fit without lateral play. Always measure the lug width by placing a ruler between the internal attachment points of the case, starting from the original strap mount.

Which type of strap do you recommend for this rose gold model?

For a rose gold Souveraine, we recommend straps in alligator (natural grain), vegetable-tanned calf leather, or isoprene rubber for more dynamic wear. Dark brown alligator creates natural chromatic harmony with rose gold, whilst deep black conveys assertiveness. Calf leather in hazelnut tones also develops patina that complements the natural ageing of the gold case over time.

How do I change the strap without damaging the case?

To change the strap safely: use a dedicated spring bar tool to gently compress the springs that hold the strap to the lugs. Avoid forcing the passant with sharp objects; calm, progressive pressure is sufficient. If you are uncertain, contact the Atelier Casati Milano, which offers professional strap replacement services by appointment with expert hands.

Can I use an aftermarket strap, or must I remain with the original strap?

Absolutely: a quality aftermarket strap in 18 mm lug width is perfectly compatible with the FP Journe Souveraine 1499.3 CAR 40 RG GR. Milano Straps offers a curated collection of artisanal straps that maintain finishing and craftsmanship standards consistent with your watch's philosophy. Versatility allows seasonal rotations without technical compromise.

How long does a leather strap last? Does it require maintenance?

The longevity of a leather strap depends on frequency of wear and material type. Alligator and calf, worn daily, maintain functional integrity for 5–8 years, developing desirable patina. They require minimal maintenance: occasional cleaning with a soft, damp cloth and protection from extreme heat and humidity. Avoid regular wetting; occasional rain does not damage vegetable-tanned leather, but prolonged immersion accelerates ageing. Casati Milano offers strap restoration services to extend the life of your favourite straps.
