Frequently asked questions

What is the lug width of the Tudor Black Bay 70150-0001?

The lug width of the Tudor Black Bay 70150-0001 is 22mm, measured between the inner edges of the spring bar pins. This dimension is standardised across the entire Black Bay family and enables the attachment of straps compatible with this precise geometry. To verify correct measurement, use a digital calliper positioned perpendicularly to the lateral pins.

What is the best strap for the Tudor Black Bay 70150-0001?

The best strap choice depends on intended use. For everyday urban wear: vegetable-tanned calf leather in Tobacco Brown to dialogue with the case patina. For sporting activities: polyester NATO in navy blue for drying speed. For diving: structured rubber for total water impermeability. Genuine alligator offers the finest compromise between aesthetics and light-duty diving functionality.

How do I change the strap on my Tudor Black Bay 70150-0001?

Position the watch with the lugs facing upward. Use a spring bar tool (specialist tool) to compress the internal elastic pin. Press the tool perpendicularly toward the case centre until the pin retracts approximately 1-2mm. Remove the old strap and insert the new one, aligning it correctly before releasing the pin. Verify that both pins are securely fastened before wearing the watch.

Can I use an aftermarket strap on my Tudor Black Bay 70150-0001?

Yes, any strap with a 22mm lug width is compatible with the Black Bay 70150-0001. Ensure thickness does not exceed 5-6mm to avoid abnormal pressure on the pins. Artisanal straps of quality offer superior performance to industrial models while maintaining durability warranties. Verify pin positioning in the new strap before prolonged use.

How long does a leather strap last on a Tudor Black Bay 70150-0001?

A vegetable-tanned calf strap lasts approximately 4-5 years with moderate daily use, longer if dried after moisture exposure. Alligator, due to its grain structure, reaches 6-7 years. Rubber has superior durability (8-10 years) but requires visual maintenance for material degradation. Storage in a dry environment and periodic treatment with specific balms significantly extend the longevity of any leather strap.
