Strap for Formula 1 Calibre 5 41 Stainless Steel / Black / Rubber

The lug width of the WAZ2113.FT8023 is 20 mm. This measurement is specific to this model and must be verified using a digital calliper positioned perpendicularly against the inner lug opening to ensure complete strap compatibility.

For the WAZ2113.FT8023, we recommend alligator leather with fine grain for formal contexts, shell cordovan for patina development over time, vegetable-tanned calf leather for versatile daily use, or FKM rubber for aquatic environments. Choice depends on intended usage context.

Remove the existing strap using a spring bar tool. Align the new strap with the corresponding lug hole on the case, then push the spring bar mechanism until fully engaged. Verify the strap is secure on both sides before wearing the watch.

Yes, aftermarket straps compatible with 20 mm lug width can be used on this model. Ensure the measurement is precisely 20 mm and that the strap is manufactured by specialised producers to guarantee constructive quality and aesthetic coherence with the instrument.

Natural leather strap lifespan varies from 3 to 5 years depending on frequency of use, sun exposure, and humidity levels. Vegetable-tanned or shell cordovan leathers perform better over time by developing patina, whilst FKM rubber offers superior durability in extreme environments.
