Frequently asked questions

What is the lug width of the Tudor Black Bay Chronograph 79360N-0006?

The lug width (ansa misura) of the Tudor Black Bay Chronograph 79360N-0006 is 22 mm. This is the distance between the two attachment points on the case. You can verify this easily by measuring the space between the inner case lugs with a calliper. This 22 mm standard offers maximum compatibility with premium artisanal straps available on the market.

What is the best strap for the Tudor Black Bay Chronograph 79360N-0006?

The best strap depends on intended use. For formal occasions, an alligator strap in cognac or slate-blue tones enhances the chronograph's inherent elegance. For daily and sports wear, a textile NATO in navy blue or fine-grained calf leather provide comfort and durability. For water activities, FKM rubber or silicone ensure waterproofness and resilience. Milano Straps offers all these options in artisanal, customisable versions.

How do I change the strap on the Tudor Black Bay Chronograph 79360N-0006?

Changing the strap is a straightforward procedure requiring only minutes. You will need a spring bar tool or small flat implement. Insert the tool under the internal spring of the first pin, maintain upward pressure, and extract the pin. Repeat for the second side. After removing the old strap, insert the pins into the case through the new strap, ensuring the springs are properly seated. Avoid excessive bending of the springs to prevent damage.

Is the Tudor Black Bay Chronograph 79360N-0006 compatible with aftermarket straps?

Yes, fully compatible. The 22 mm lug width is a widely adopted standard and allows the use of any high-quality artisanal strap with the same width and compatible spring bar setup. Milano Straps offers a comprehensive range of artisanal 22 mm straps, customisable in leather, colour, size and details (initials, thread colour, buckle). Compatibility is total, guaranteed by the standardisation of the case's inner lugs.

How long does a leather strap last on the Tudor Black Bay Chronograph 79360N-0006?

The lifespan of a leather strap depends on material, frequency of wear and climatic conditions. An alligator or shell cordovan strap can last 5–8 years with daily use and proper maintenance (protection from excess humidity and direct UV rays). Fine-grained calf typically lasts 3–5 years. Milano Straps guarantees 18 months on all artisanal straps and offers assistance for restoration and replacement via the Casati Milano atelier.
