The Black Bay 79733N-0006, seen from the bench

The Tudor Black Bay 79733N-0006 is the contemporary evolution of an icon born from Tudor's diving experience in the 1950s and 1960s. This two-tone model in yellow gold and stainless steel combines rigorous technical instrumentation with timeless aesthetics. Powered by the Tudor MT5612 caliber—an in-house movement offering hours, minutes, seconds, date, and Chronometer certification—the watch features a 41mm case with 200m water resistance. The 22mm lug width provides the ideal balance between visual proportion and practical versatility for strap selection.

Frequently asked questions

What is the lug width of the Tudor Black Bay 79733N-0006?

The lug width of the Tudor Black Bay 79733N-0006 is 22 millimetres. This measurement is essential when selecting a compatible strap. You can verify it by measuring the space between the lugs protruding from the case, perpendicular to their axis. All 22mm straps available on milanostraps.it are guaranteed compatible with this model.

Which strap pairs best with the two-tone Tudor Black Bay 79733N-0006?

For the two-tone Black Bay in yellow gold and stainless steel, we recommend a strap in vegetable-tanned Tuscan calf leather in honey or cognac tones, which creates chromatic harmony with the case's yellow gold. Alternatively, dark brown or black alligator emphasises the watch's technical character. For those preferring practicality, a black FKM rubber strap with refined texture offers sporty elegance and maximum versatility.

How do I change the strap on a Tudor watch?

To change the strap on a Tudor Black Bay, you must remove the pins connecting the strap to the case. Obtain a pin removal tool – available on milanostraps.it – and gently push it from the back of the pin until it emerges completely. Once both pins are removed, the old strap slides away. Insert the new strap, aligning it correctly, and reinsert the pins from outside inwards, ensuring they sit securely. If you prefer professional assistance, Casati Milano atelier offers strap fitting services.

Is an aftermarket strap for the Tudor Black Bay 79733N-0006 compatible with the two-tone case?

Yes, any 22mm strap is mechanically compatible with the 79733N-0006, regardless of material. However, aesthetic compatibility depends on your personal preference. With a two-tone case in yellow gold and stainless steel, straps in superior quality leather, genuine alligator, or premium rubber will create visually harmonious and refined combinations, enhancing the watch's two-tone character.

How long does a leather strap last on the Tudor Black Bay?

A superior quality leather strap, manufactured with vegetable tanning or genuine alligator, typically lasts 3–5 years with regular use. Longevity depends on maintenance: avoid prolonged exposure to moisture and direct sunlight, clean periodically with a soft cloth, and occasionally apply leather balm. Rotating with other straps significantly extends lifespan. FKM rubber straps last longer (5–7 years) due to the material's inherent resistance to environmental agents.
