Frequently asked questions

What is the lug width of the Panerai Radiomir 1940 PAM00513 (aka: PAM513, PAM 513)?

The Panerai Radiomir 1940 PAM00513 is equipped with a lug width of 22mm. This dimension is specific to this model and represents the proportional balance between the 42mm case diameter and the lug height. Measuring the lug width correctly means positioning a digital caliper between the inner poles of the two lugs; a tolerance of ±0.5mm is generally acceptable. It is essential to verify this measurement before ordering an aftermarket strap to avoid incompatibility or ergonomic misfit.

Which strap is best suited for the Panerai Radiomir 1940 PAM00513 in red gold?

Given the aristocratic character of the Red Gold version, the optimal choice falls on alligator or crocodile in dark shades (black, dark brown, cognac) that enhance the chromatic contrast with red gold. Alternatively, aged vegetable tanned calf leather with fine grain and satin finish creates a more casual-elegant aesthetic while maintaining stylistic coherence. Butadiene rubber is advisable for sports or aquatic contexts, although it contrasts with the dress nature of the model. Avoid NATO or textile straps that would undermine the haute horlogerie profile of this watch.

How do I change the strap on my Panerai Radiomir 1940 PAM00513?

The Panerai Radiomir 1940 PAM00513 is equipped with polished wire lugs without a quick-release system, which means the strap is removable only by using a special tool (spring bar tool) to compress the internal springs. Position the tool in the lateral slots of the springs, gently push to release them from the lug holes, and extract the strap. The operation requires care to avoid scratching the red gold lugs. If you are not experienced, we recommend entrusting the operation to a professional: the Casati Milano atelier offers this service during the creation of custom bespoke straps.

Is there a compatible aftermarket strap of equivalent quality for the PAM00513?

Yes. Milano Straps provides 22mm straps designed specifically for the Panerai lug width, in premium leathers (alligator, calf, technical rubber) and with high-quality finishes. Compatibility is guaranteed by dimensional precision (22mm) and adaptation to polished wire lugs. For a completely personalized and bespoke experience, the Casati Milano atelier creates custom straps with personal leather selection, progressive updates, and 18-month warranty, allowing perfect aesthetic synergy with your red gold watch.

How long does a leather strap last on the Panerai Radiomir 1940 PAM00513?

The lifespan of a leather strap depends on the type of leather, frequency of use, and climatic conditions. A quality alligator or crocodile strap, worn daily, maintains structural integrity and flexibility for 3-4 years; well-aged vegetable tanned calf can last 2-3 years before requiring replacement due to aesthetic wear (cracking, thinning). Technical rubber offers superior durability (5+ years) but is less reversible in terms of patina development. Milano Straps and the Casati Milano atelier provide straps with an 18-month warranty against manufacturing defects, and both offer regeneration services (refinishing, reworking) to extend the useful life of premium straps.
