Strap for Heritage Black Bay Steel Manufacture / Fabric

The lug width of the Tudor Black Bay 79730-0004 is 22 millimetres. This dimension is measured from lug to lug on the case and determines compatibility with aftermarket straps. To verify it, remove the current strap and measure the distance between the two metal lugs on the case.

The Tudor Black Bay 79730-0004 pairs excellently with vegetable-tanned leather straps, alligator, and technical formats such as NATO. Selection depends on context: textured leather for daily elegance, vegetable-tanned alligator for formal occasions, NATO for water sports and versatility. All must feature 22mm lug width.

To change the strap, you need a spring bar tool. Position the tool in the small hole on the side of the lug, gently push to extract the internal spring and slide the strap out. Reverse the operation to install the new one: align the lugs to the slots and press until you hear the spring click.

Yes, any strap with 22mm lug width is compatible with the 79730-0004. Artisanal leather straps in vegetable tanning, alligator or other quality materials guarantee comfort and durability, often superior to the original. Always verify that the width corresponds exactly to 22 millimetres.

A vegetable-tanned leather strap lasts an average of 3–5 years with moderate daily use, developing a unique patina. Alligator models are more durable and can exceed 7 years. Lifespan depends on humidity exposure, perspiration and frequency of use. Proper maintenance—periodic cleaning and drying—significantly extends service life.
