Strap for Heritage Black Bay Black S&G / Stainless Steel / Yellow Gold / Black / Strap

The Tudor Black Bay 79733N-0007 requires exclusively 22mm watch straps. This width is the standard for 41mm diameter watches and ensures harmonious proportions between case and strap. Lug width measurement should be taken from the inside of one spring bar to the inside of the opposite spring bar, perpendicular to the case body.

For the bicolour Black Bay S&G, alligator leather with vegetable tanning represents the supreme choice, enhancing the luxurious character through the natural grain of the leather. Alternatively, shell cordovan offers superior density and longevity with a lustre that amplifies the bicolour contrasts of the case. Medium-grain calf leather is a refined solution for those preferring a more uniform surface.

Strap replacement requires a spring bar tool. Position the watch on a stable surface, insert the tool tip into the upper lug exerting gentle pressure to release the spring, then slide out the old strap. Repeat the procedure on the lower lug. Insert the new strap ensuring the springs are perfectly seated in the lug slots.

No. The 22mm straps from the 79733N-0007 are compatible exclusively with other Tudor (or other brands) featuring the same 22mm lug width. Always verify your watch reference before purchasing: different diameters and lug widths require specific straps to avoid movement and risk of damage.

Durability depends on the material and usage patterns. A high-quality alligator or shell cordovan strap with vegetable tanning develops beautiful patina and can last 5–8 years with regular wear. Calf leather has an average lifespan of 3–5 years. Prolonged exposure to moisture, perspiration, and UV rays accelerates ageing. Proper maintenance (drying after use, annual conditioning) significantly extends longevity.
