Frequently asked questions

What is the lug width of the Tudor Black Bay Chronograph 79360N-0001?

The lug width of the Tudor Black Bay Chronograph 79360N-0001 is 22 millimetres. This measurement is standard across all examples of this reference. To verify strap compatibility, measure the distance between the inner edges of the two lugs: it should fall between 21.5 and 22.5 millimetres to ensure precise fit without excessive play or insertion difficulty.

Which strap is most suitable for the Tudor Black Bay Chronograph 79360N-0001?

The ideal strap depends on your intended use and aesthetic preference. For a classic-sporting approach, we recommend dark brown alligator or vintage-aged calf leather, which amplify the model's racing DNA. Should you seek a refined and enduring solution, shell cordovan develops a rich and singular patina over time. For maximum versatility and convenient replacement, NATO fabric or FKM rubber straps remain excellent choices, keeping visual focus on the dial and chronograph counters.

How do you change the strap on the Tudor Black Bay Chronograph 79360N-0001?

The Tudor Black Bay Chronograph 79360N-0001 features removable lugs. To change the strap: 1) Position the watch on a soft surface. 2) Use a spring bar tool to gently push the pin downward from one side, creating space to extract it. 3) Once the pin is removed, the lug comes free easily. 4) Insert the new strap into the lugs and reinsert the pin in the same direction, ensuring both sides of the pin are properly seated in the case holes. If you lack a spring bar tool, specialist suppliers such as Milano Straps offer strap-change services.

Is the Tudor Black Bay Chronograph 79360N-0001 compatible with quality aftermarket straps?

Yes, the Tudor Black Bay Chronograph 79360N-0001 is fully compatible with quality artisanal aftermarket straps, provided they respect the 22-millimetre lug width. Milano Straps offers online 22mm straps in alligator, calf, shell cordovan and fabric, all tested and compatible with this reference. The key is always to verify lug width specifications before purchase and to rely on suppliers that guarantee precise manufacturing tolerances, avoiding generic straps that may present play or insertion difficulty.

What is the average lifespan of a leather strap for the Tudor Black Bay Chronograph 79360N-0001?

The lifespan of a leather strap depends on tanning quality, usage and environmental conditions. A strap in alligator or vegetable-tanned calf leather, produced to artisanal standards, maintains good functionality between 5 and 10 years of regular use. Shell cordovan, owing to its extreme density, can last 15 years or more, becoming ever more beautiful with time. To prolong strap life, avoid prolonged moisture exposure, occasionally apply natural leather balm and rotate multiple straps if you use the watch regularly. Milano Straps offers an 18-month warranty on custom straps realised by the Casati Milano atelier, covering manufacturing defects.
