For the Q8002520 in rose gold, the most suitable materials are alligator crocodile belly for formal occasions and box-calf leather for daily use. Regarding color, dark burgundy, tobacco brown, and forest green pair particularly well with the warmth of rose gold. Casati Milano offers a bespoke service to create the perfect strap with leather selection in the atelier.

The strap of the Geophysic Q8002520 is secured with standard 20 mm spring bars. For replacement, simply use a dedicated spring bar tool: compress the bar, remove the strap from the lug, and insert the new one. It is recommended to have this operation performed by a watchmaker or specialized retailer to avoid scratches on the rose gold lugs.

Yes. The Q8002520 uses standard 20 mm spring bars, which ensures full compatibility with any quality aftermarket strap with that lug width. milanostraps.it offers a selection of handcrafted leather, alligator, calf, and NATO straps specifically selected for this width, with the option of bespoke customization through the Casati Milano atelier.

The lifespan of a leather strap depends on the material, care, and frequency of use. A quality alligator strap, properly treated and alternated with other examples, can last 3 to 5 years while maintaining optimal appearance and structure. Box-calf leather tends to develop a characteristic patina over time. Casati Milano guarantees 18 months against manufacturing defects on all straps made in the atelier.
