Frequently asked questions
What is the exact lug width of the Tudor Royal 28400-0006?
The lug width of the Tudor Royal 28400-0006 is 20mm, measured between the centres of the case lugs. This dimension is specific and allows the use of straps compatible with the same millimetre tolerance.
Which strap pairs best with the Tudor Royal 28400-0006?
Alligator in vegetable tanning grey and smooth Bordeaux calf leather represent the most refined choices. For summer use, NATO fabric straps in navy blue provide practicality whilst maintaining elegance. The choice depends on the occasion and the character you wish to impart to the watch.
How do I change the strap on my Tudor Royal 28400-0006?
Use a spring bar tool to extract the pins from the case lugs. Position the small hook of the tool under the pin, push gently upwards and the pin will release. Repeat on the other side, then insert the pins into the new strap by aligning the holes and pressing until the attachment clicks.
Can I use an aftermarket strap on this model?
Yes, provided the strap respects the 20mm lug width. High-quality artisanal straps guarantee Swiss tolerances and perfect fitting. Avoid generic straps as they may slip laterally or fail to insert correctly.
How long does a leather strap last on my watch?
A high-quality leather strap, such as alligator or shell cordovan, typically lasts 3-5 years with regular maintenance. Durability depends on frequency of use, humidity and care. Periodically, nourish the leather with oils specific to watchmaking to maintain elasticity and slow ageing.
