The Radiomir PAM01643, seen from the bench

The Panerai Radiomir PAM01643 features a 45mm cushion case in bronze and stainless steel, housing the P.6000 manual-wind movement with hours, minutes, and small seconds. The case diameter positions this model within sporty professional watches, while the 26mm lug width is a specific construction feature. Bronze develops a dark patina over time, serving as a protective layer. Water resistance reaches 100 meters for daily marine and pool use.

Frequently asked questions

What is the lug width of the Panerai Radiomir PAM01643?

The Panerai Radiomir PAM01643 uses a 26mm lug width. This measurement is specific to Panerai models with a 45mm case from the Radiomir family. To verify correctly, measure the distance between the attachment pins inside the lugs: the measurement must be exact to ensure the perfect fit of your new strap.

Which strap is most suitable for the Panerai Radiomir PAM01643?

For the PAM01643 we recommend straps in aged calf leather or alligator, which emphasize the instrumental character of the watch. Alligator offers natural texture and patina that evolves over time, while vegetable-tanned calf ensures tactile comfort and resistance. For tactical or underwater use, the NATO strap in Cordura canvas with leather keeper represents the most authentic choice, true to its military heritage.

How do I change the strap on my Panerai Radiomir PAM01643?

The change requires a dedicated tool (spring bar tool) to extract the attachment pins. Position the watch on a stable surface, use the tool to gently lift the pin from one side, remove the old strap and insert the new one in the same direction. The PAM01643 has straight 26mm lugs: verify that the new strap is cut exactly for this measurement.

Can I use compatible aftermarket straps on my PAM01643?

Yes, provided they are made specifically for 26mm lugs. Compatible artisanal straps from Milano Straps are available in various finishes, leathers and colors. We recommend made in Italy straps custom-made to measure, which respect the visual proportions of the 45mm case and ensure certified durability.

How long does an artisanal leather strap last on a Panerai?

A quality artisanal strap, made in vegetable-tanned or alligator leather, has an average lifespan of 3-5 years with daily use and regular maintenance. Factors such as climate, frequency of wear and care influence longevity. Casati Milano atelier offers an 18-month warranty on bespoke straps and support for cleaning and conservation over time.
