Strap for Tudor Black Bay 58 79018V

The lug width of the Tudor Black Bay 58 reference 79018V is 20mm. This measurement is determined by the distance between the two lugs (metal attachments) of the case and is essential for selecting a compatible strap. An accurate measurement with callipers between the lugs ensures you purchase a strap of the correct width.

For the Black Bay 58 in solid yellow gold, alligator is the most coherent choice from an aesthetic standpoint. A natural tan or cognac alligator strap enhances the warmth of the yellow gold, whilst a black alligator creates dramatic contrast with the blue-red bezel. Vegetable-tanned leather is a refined alternative, developing a natural patina over time, or FKM rubber for those requiring versatility and practicality.

To change the strap, use a dedicated tool (strap removal tool or small screwdriver) to gently push the spring bar securing the strap to the lugs. Position the tool in the small groove visible at the sides of the case, applying uniform pressure. Once the spring bar is extracted, the strap will release. Align the new strap with the lug holes, then carefully reinsert the spring bar, ensuring it is fully locked.

Yes, any strap with a 20mm lug width is compatible with the Black Bay 58 79018V. Quality aftermarket straps allow customisation in leather type, dimensions, spring bar thickness and thread colour. It is crucial to verify that the new strap has exactly 20mm width to prevent instability or stress on the case lugs.

The lifespan of a leather strap varies depending on leather quality and wear. A quality alligator or calf leather strap can last 3–5 years with regular use, up to 7–8 years with proper maintenance (drying after moisture exposure, periodic cleaning). Structured rubber has greater water and UV resistance, lasting 4–6 years. To extend strap life, avoid prolonged contact with salt water and replace it when showing signs of structural failure.
