Strap for Autavia Calibre 5 Bronze / Year of the Rat

The lug width of the TAG Heuer Autavia WBE5193.FC8300 is 20mm. This measurement represents the distance between the two metal lugs (the case attachments) where the strap inserts. It is a constructive specification and should not be confused with the total width of the strap at the wrist. You can verify it using a digital calliper or a tailor's ruler by measuring directly the space between the two spring bar pins.

The best strap depends on use and aesthetic preferences. For formality and elegance, alligator in cognac or tobacco colour creates a perfect dialogue with the bronze case. For everyday versatility, vegetable-tanned calf leather in smoke grey or a cotton NATO maintains the original aviator spirit. For sophisticated contrast, a black or navy blue alligator on steel and patinated bronze offers contemporary aesthetic tension. Each material should be evaluated based on the context of use and the patina that the bronze develops over time.

To change the strap, obtain a tool called a spring bar remover or consult a professional watchmaker. Position the watch with the lugs facing upward. Gently insert the tool into the side gaps of each spring bar pin, push lightly to compress the internal spring and slide the pin outward. Remove the old strap. Reverse the procedure with the new strap, ensuring that the pins are fully inserted into the lugs. Avoid forcing to prevent damage to the case.

All artisanal straps with a 20mm lug width are compatible with the TAG Heuer Autavia WBE5193.FC8300. This includes alligator, calf leather, shell cordovan, ostrich leather, NATO, technical rubber and canvas. Mechanical compatibility is guaranteed by the standardisation of lug width. On milanostraps.it a wide selection of 20mm straps is available ready for shipment, customisable in size, initials and stitching colour, or created to measure by the Casati Milano atelier with personal consultation.

The lifespan of a leather strap depends on the quality of the material, the tanning process and daily use. An artisanal-quality alligator or calf leather strap, with vegetable tanning, typically lasts 3-5 years with regular use and proper maintenance. Longevity increases if the strap is rotated (not worn every day) and protected from excessive humidity and intense perspiration. Periodic maintenance with specific products (natural-based balms, soft brushes) significantly extends the strap's life. Casati Milano offers an 18-month warranty on artisanal straps, with repair and regeneration options thereafter.
