Panerai
Luminor Due PAM01301— lug 20mm

The Panerai Luminor Due PAM01301 features a 20mm lug width. This width is specific to the proportions of the 38mm case and is critical for compatibility with aftermarket straps. The measurement is verified by placing a caliper between the centers of the attachment holes on the case: the distance is precisely 20mm.

The choice depends on intended use: Mississippi alligator offers formal luxury with consistent natural texture; vintage-waxed calf evolves aesthetically over time, developing patina; technical nato in cordura is ideal for water sports due to moisture resistance; FKM rubber is necessary for saltwater diving. On a blue or black dial, cognac alligator or ink-black calf create perfect minimalist contrast.

Remove the caseback using the specific Panerai case opener tool—pay attention to the gasket. The spring bars are fixed with pass-through pins that cannot be removed from the inside: use a dedicated removal tool to slide the lateral spring and release the bar. Reinsert the spring into the new strap, ensuring that the attachment holes align with the 20mm centers. Some prefer to have this operation performed by experts to avoid damaging the caseback gasket.

All straps with a 20mm lug width are mechanically compatible. However, we recommend specific models from specialists like Milano Straps, which offer straps designed for the proportions of the 38mm case, avoiding the aesthetic oversizing typical of straps designed for 44mm Luminor models. The atelier Casati Milano creates personalized custom straps with direct material selection and updates via WhatsApp.

A quality alligator or calf strap, with proper maintenance, lasts 4-6 years of daily wear before showing structural deterioration. Natural leather ages gracefully, developing patina and creases that tell the story of use. Factors such as UV exposure, repeated saltwater exposure, and lack of treatment accelerate aging. FKM rubber straps last 5-8 years without aesthetic degradation, as they are immune to mold and chemical oxidation. The atelier Casati Milano guarantees 18 months for custom-made straps.
