Strap for Tudor Black Bay Chronograph 79360DK

The lug width of the Tudor Black Bay Chronograph 79360DK is 22mm. This measurement represents the distance between the two horizontal lugs on the case where the strap is installed. The 22mm specification provides the correct proportion for the 41mm case and ensures balanced visual transition and ergonomic weight distribution on the wrist.

The optimal strap depends on intended use. For formal elegance, we recommend genuine alligator with tight grain and visible patina; for daily versatility, vegetable-tanned calf leather; for connoisseurs, shell cordovan in burgundy tones that develop rich patina over time. For sports without maintenance requirements, FKM rubber or NATO fabric in dark tones provide grip and weather resistance.

Strap replacement requires a spring bar tool. Position the tool under the spring bar at one lug end, apply gentle pressure to compress the internal spring, and push the bar out of its seat. Repeat on the opposite side. Insert the spring bars of the new strap into the lug seats and ensure they are fully secured before wearing the watch.

Any strap with an exact 22mm lug width is compatible with the 79360DK. Always verify that the strap ends measure exactly 22mm wide (measured centre-to-centre of the lug holes). Reputable brands such as Hirsch, Barenia, and bespoke ateliers like Casati Milano produce straps specifically engineered for this specification.

A high-quality leather strap (alligator, shell cordovan, vegetable-tanned calf) typically lasts 3–5 years with daily wear, depending on tanning method and environmental exposure. Alligator generally outlasts other leathers due to fibre density; shell cordovan improves with age through patina development. Periodic maintenance—gentle cleaning and conditioning with specialist creams—significantly extends longevity.
