Strap for Seamaster Diver 300M Quartz 41 Stainless Steel / Yellow Gold / Blue / Bracelet

The lug width is 20 millimetres. To verify, position a digital caliper between the two metal pins that protrude from the case, below the 12 and 6 on the bezel. The 2442.80.00 features straight lugs without flaring, a standard characteristic in professional models of this generation.

It depends on use: alligator in cognac or black tones represents the aesthetic pinnacle for formal elegance; vegetable-tanned calf offers modernity and patina over time; shell cordovan guarantees hardness and natural polish that evoke the case steel; butadiene rubber is ideal for intensive underwater use.

The strap is connected to the case through two horizontal riveted pins (one-piece bar). Use a pin removal tool or dedicated instrument to gently extract the pin from one side, taking care not to scratch the case. Subsequently, remove the worn strap and insert the new one by aligning the holes, then rivet the pin back.

Yes, any 20mm strap is compatible with the 2442.80.00 since the lug width is standard. However, ensure that the leather thickness does not exceed 3.5 millimetres to avoid friction with the lugs. On milanostraps.it you will find customizable 20mm straps already sized for this measurement.

A quality alligator or calf strap, with proper maintenance (drying after water contact, occasional application of nourishing cream), lasts 4-6 years of daily use. Shell cordovan, due to its greater density, easily reaches 7-8 years. Vulcanized rubber resists longer but requires periodic inspection of the pin security.
