Frequently asked questions

What is the lug width of the Tudor Black Bay 79230R-0002?

The lug width of the Tudor Black Bay 79230R-0002 is 22 millimetres. This measurement corresponds to the distance between the two horizontal pins that protrude from the case. All compatible straps must feature exactly this width to fit correctly without play or forcing.

Which strap should I choose for the Tudor Black Bay 79230R-0002?

The choice depends on intended use. For formal elegance, we recommend vegetable-tanned alligator or smooth leather in dark tones. For sporting use and wet environments, premium NATO in anthracite maintains the instrument's military heritage. Butyl rubber suits diving and water activities. Cognac brown and navy blue offer harmonious colour pairings with the dial's burgundy hue.

How do I change the strap on the Tudor Black Bay 79230R-0002?

The change is straightforward: use a spring bar tool to push the small elastic pin beneath the case lug. The pin will retract, allowing you to remove the old strap. Position the new strap and reinsert the pin until it clicks into place. Ensure the pin is fully inserted on both sides before wearing the watch.

Are aftermarket straps compatible with the Tudor Black Bay 79230R-0002?

Yes, all straps with a 22-millimetre lug width are compatible with the 79230R-0002. Quality aftermarket straps allow you to personalise the instrument according to your aesthetic preference and occasion. We recommend selecting specialists who respect case proportions and use superior leather to guarantee durability over time.

How long does a leather strap last on the Tudor Black Bay 79230R-0002?

A quality leather strap, treated with vegetable tanning, typically lasts 3-5 years with daily wear. Longevity depends on frequency of use, exposure to humidity and sunlight, and care applied. Leather ages and develops natural patina, a characteristic appreciated by watch enthusiasts. Artisanal brands offer warranties from 18 to 24 months on straps, covering any manufacturing defects. You can extend lifespan with periodic maintenance and replacement of spring bars if worn.
