Frequently asked questions

What is the lug width of the Tudor Ranger 79950-0003?

The lug width of the Tudor Ranger 79950-0003 is 20 mm. This measurement is specific to this model and reflects the elegant proportioning of the 39 mm case. To verify the lug width accurately, measure the distance between the centres of the two lug pins protruding from the case using a digital calliper.

Which strap is most suitable for the Tudor Ranger 79950-0003?

For the Ranger 79950-0003, we recommend alligator with vegetable tanning, which develops natural patina over time, transitioning from dark brown to amber tones. This pairing enhances the black dial and the field watch character of the model. An elegant alternative is burgundy chrome-tanned calf, which is more predictable in durability. On milanostraps.it you will find 20mm straps ready for dispatch and customisable according to your colour preferences.

How do I change the strap on my Tudor Ranger 79950-0003?

Remove the current strap using a spring bar tool. Position yourself on the dial side, gently push the spring bar towards the case centre to release one end, then extract the pin completely. Repeat on the opposite side. To install the new 20mm strap, align the pin to the space between the lugs and press until you hear the spring bar click. Avoid non-professional tools that could scratch the case.

Can I use an aftermarket strap on a Tudor Ranger 79950-0003?

Yes, the Tudor Ranger 79950-0003 is fully compatible with 20mm aftermarket straps, which is the standard measurement for its lugs. Milanostraps.it offers handcrafted 20mm straps customisable in leather, colours and finishes. Always verify that the strap is cut specifically for 20mm to ensure a perfect fit without excessive play.

How long does a leather strap last on a Tudor Ranger 79950-0003?

Durability depends on the quality of leather and intensity of use. An alligator strap with vegetable tanning resists 3-5 years in daily wear, evolving aesthetically with patina. Chrome-tanned calf lasts 2-3 years if exposed to humid climates. To prolong its lifespan, protect it from prolonged salt water exposure and direct sunlight. Casati Milano offers an 18-month warranty and specialised maintenance services.
