Strap for Heritage Black Bay Steel Manufacture / Strap

The Tudor Black Bay 79730-0005 features a lug width of 22mm. This is the factory-standard dimension for this reference and must be verified by measuring between the lugs before ordering an aftermarket compatible strap.

For the Black Bay 79730-0005, we recommend natural alligator in dark brown or black to emphasise vintage character, vegetable-tanned calf with factory finish for construction modernity, or NATO textile in recycled yarn for tropical environments. Selection depends on use case: technical diving requires FKM rubber, everyday smart-casual favours alligator or calf.

Strap change requires a spring bar tool to extract the lug pins from either side. Position the tool under each pin, press gently toward the centre, withdraw the pin and repeat on the opposite side. Verify that the new strap's lug width is exactly 22mm and the passant thickness does not exceed 2.5mm to avoid crown operation difficulties.

Yes, any strap with a 22mm lug width is compatible with the Tudor Black Bay 79730-0005, provided the passant thickness does not exceed 2.5mm. Milano Straps supplies measurement guidance with every strap to ensure constructive compatibility and installation ease without crown compression.

A vegetable-tanned leather strap lasts an average of 3-5 years in daily use with correct maintenance (saltwater cleaning, rapid drying, biannual conditioning). Natural alligator develops pleasant patina over time and strengthens structurally; shell cordovan retains original brilliance longer but requires greater protection in humid climates. Factory FKM rubber, if used in diving, maintains hydrophobicity for 5-7 years.
