Frequently asked questions

What is the lug width of the Tudor Black Bay 7941A1A0NU?

The Tudor Black Bay 7941A1A0NU features a lug width of 22mm. This measurement is specific to this model and represents the space between the case lugs. It is essential to verify the exact measurement between the inner edges of both lugs before ordering a strap to ensure compatibility.

Which strap is most suitable for the Tudor Black Bay 7941A1A0NU?

For the Tudor Black Bay 7941A1A0NU, we recommend vegetable-tanned calf leather straps for a balance between formality and everyday practicality. Alligator leather is ideal if you wish to emphasise the tactical character of the model, whilst shell cordovan represents a premium choice for those seeking discrete luxury. For summer use, natural fibre NATO straps maintain good breathability whilst preserving the model's identity.

How do I change the strap on my Tudor Black Bay 7941A1A0NU?

To change the strap on your Tudor Black Bay 7941A1A0NU, use a spring bar tool (strap change tool). Position the tool beneath the lateral lug, gently press to compress the internal spring, then extract the bar. Repeat on the other side. Insert the new spring bar into your compatible 22mm strap and snap the bar into the case lugs. This is a delicate operation requiring care to avoid scratching the AISI 316L stainless steel case.

Can I use an aftermarket strap on my Tudor Black Bay 7941A1A0NU?

Yes, absolutely. The Tudor Black Bay 7941A1A0NU is fully compatible with quality aftermarket straps sized 22mm. It is important that the strap is crafted by specialised luxury watch artisans to guarantee impeccable finishing, solid stitching and structural compatibility. Verify that the spring bars are well-soldered and the strap shows no deformation in the lugs.

How long does a natural leather strap last on a Tudor Black Bay 7941A1A0NU?

A natural leather strap with vegetable tanning or alligator, if properly maintained, typically lasts 18-36 months on a daily-wear watch. Durability depends on exposure to moisture, perspiration, frequency of wear and leather quality itself. Casati Milano straps are guaranteed for 18 months. To extend lifespan, dry the strap after water exposure and store it away from direct heat sources.
