Frequently asked questions

What is the lug width of the Tudor Black Bay M79210CNU-0011?

The lug width of the Tudor Black Bay M79210CNU-0011 is 22mm. This measurement represents the distance between the two anchor pins where the strap connects to the case. It is essential to measure correctly before purchasing an aftermarket strap: verify the empty interval between the lugs, not the pin diameter itself.

What is the best strap for the Tudor Black Bay M79210CNU-0011?

There is no universal choice, but rather choices in dialogue with the watch's character. Black alligator accentuates the ceramic case contrast; vegetable-tanned calf leather offers aesthetic evolution over time; premium technical NATO straps maintain the tool watch dryness for frequent water users; vulcanised rubber speaks directly to the diving heritage. The choice depends on intended use and personal aesthetics.

How do I change the strap on the Tudor Black Bay M79210CNU-0011?

Removing the strap requires a spring bar tool, a dedicated instrument with a slot to engage the anchor pins. Insert the tool between the case lug and the strap at the pin contact point, and press gently. The pin will retract slightly, allowing the strap to slide free. Repeat on the other side. Install the new strap by reversing the process, ensuring the pins enter fully into their respective slots.

Is the Tudor Black Bay M79210CNU-0011 compatible with 22mm aftermarket straps?

Yes, the M79210CNU-0011 accepts aftermarket straps with 22mm lug width, provided they are constructed to Tudor standards: appropriate lugs, consistent width, and pin diameter of 1.8–2.0mm. Milano Straps offers a specialised collection of 22mm artisanal leather, premium NATO, and rubber straps, all tested for compatibility with this reference.

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

A quality artisanal leather strap, such as those crafted with vegetable tanning or alligator, maintains functionality and aesthetics for 3–5 years under regular use. The natural patina that develops is part of its beauty. Longevity depends on water exposure, UV rays, and cleaning frequency. Milano Straps offers an 18-month warranty on straps and support for maintenance and replacement.
