Strap for Praeludium Chronograph

The lug width of the P41.031-A02 is 22mm. This measurement represents the distance between the two anchor pins protruding from the case and is the exact strap size requirement. Measuring is straightforward: position a ruler between the two horizontal case lugs.

For the Praeludium Chronograph, we recommend vegetable-tanned Tuscan leather in dark tones (dark brown or black), which emphasises the technical elegance of the ETA 7753 chronograph. Alternatively, alligator for a luxury option, or NATO/structured rubber for more sporting applications. All 22mm straps from Milano Straps are compatible.

To change the strap, use a spring bar tool. Insert the tool into the lateral hole of the pin until compressing the internal spring, then gently extract the pin from the case. Repeat for the second pin. To install the new strap, align the holes and reinsert the pins until the locking click is felt.

Yes, absolutely. Any quality 22mm strap is compatible with the P41.031-A02. Milano Straps offers an extensive selection of 22mm straps in different materials and finishes, all tested for reliability and comfort. Dimensional compatibility is the sole requirement.

A vegetable-tanned leather strap, if subjected to regular maintenance (gentle cleaning and occasional treatments with specialist products), maintains structural integrity for 3-5 years of daily wear. Sports straps (NATO, rubber) have longer durability. Visible wear on leather is normal and part of its beauty: the nobilitating patina is desirable.
