Frequently asked questions

What is the lug width of the Tudor Ranger 79950?

The Tudor Ranger 79950 features a lug width of 20mm. This measurement is determined by measuring the distance between the spring bar pins that attach the strap to the case. Verifying this dimension is essential before purchasing an aftermarket strap to ensure compatibility.

Which strap is most suitable for the Tudor Ranger 79950?

For the Ranger 79950, alligator straps are recommended for sartorial elegance, vegetable-tanned calf leather for authenticity and natural ageing, shell cordovan for durability and natural lustre, or canvas NATO straps for practical sportiness. Your choice depends on intended use: formal with alligator, daily wear with calf or shell cordovan, casual with NATO or rubber.

How do you change the strap on a Tudor Ranger 79950?

To change the strap, you will need two tools: a spring bar tool (extractor) and a stable work surface. Position the spring bar on the extractor, press gently to release the pin, then remove the strap from the case. Insert the new strap into the opposite pin, align and press until you hear a click. Repeat on the other side. The operation takes only minutes and requires careful attention to avoid scratching the case.

Is a 20mm strap from another brand compatible with the Tudor Ranger 79950?

Yes, any strap with a 20mm lug width is compatible with the Ranger 79950, regardless of brand. However, ensure that the overall width of the strap (considering the shape of the 39mm case) is not excessive, as overly thick straps may not fit properly. We recommend thicknesses between 3.5mm and 5mm for balanced proportions.

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

A premium leather strap on a Tudor Ranger 79950 typically lasts 18-36 months with daily wear, depending on the leather quality, tanning method and use conditions. Vegetable-tanned leather can last longer as it improves with age, whilst chrome-tanned leather tends to show visible wear more quickly. Exposure to water, heat and sunlight accelerates deterioration. Regular maintenance—cleaning and conditioning—significantly extends durability.
