Strap for Heritage Black Bay Black Chronograph / Strap

The lug width of the Tudor Black Bay Chronograph 79350-0005 is 22mm. This is the standard distance between the case lugs, regardless of the strap thickness. This proportion is specific to the 41mm case diameter and is essential to ensure the strap integrates perfectly with the case geometry without visual misalignment.

For the Black Bay Chronograph, we recommend alligator leather in black for a versatile formal-sporty look, Italian leather with a textured finish for artisanal aesthetics that age gracefully, or natural rubber straps for intensive nautical and sporting use. The choice depends on primary use: the chronograph retains elegance even with robust materials, thanks to its inherently racing-oriented design.

Use a spring bar tool: insert the flat end into the lateral slot of the lug and gently lift to free the spring pin. Remove the pin from the lug. Repeat on the other side. Align the new strap's holes with the case lugs, then press the pin until you hear the spring mechanism click into position. Many jewellers offer this service free of charge.

Yes, any strap with a 22mm lug width is compatible. However, we recommend straps crafted by specialised artisans: build quality, leather type, and buckle construction (deployante, keepers, or standard) significantly affect comfort and longevity. Italian artisanal leather straps guarantee superior finishing and durability compared to mass-produced alternatives.

A naturally tanned leather strap typically lasts 3–5 years of daily wear, depending on water exposure, sunlight, and maintenance level. Leather is a living material that wears naturally but ages elegantly, developing a rich patina. A rubber or composite strap lasts 5–7 years. Regular conditioning with appropriate creams significantly extends the lifespan of any leather strap.
