FAQ

What is the lug width of the Rolex GMT-Master 116710BLNR-0002?

The Rolex GMT-Master 116710BLNR-0002 features a lug width of 20mm. This measurement represents the distance between the inner edges of the case lugs and is essential for selecting a compatible strap. Always verify this dimension before purchasing to avoid compatibility issues.

Which strap is most suitable for the Rolex GMT-Master 116710BLNR-0002?

For the GMT-Master 116710BLNR-0002, alligator leather is the most elegant choice, as its natural grain beautifully complements the ceramic Pepsi bezel.

Vegetable-tanned calf leather provides a more natural aesthetic, whilst NATO fabric straps guarantee maximum daily versatility.

How do I change the strap on the Rolex GMT-Master 116710BLNR-0002?

The strap is changed using a spring bar remover tool. Remove the tension spring from the lugs, extract the original strap, position the new strap onto the lugs, and reinsert the spring. This procedure requires careful handling to avoid scratching the case. Professional service from a certified watchmaker is recommended for optimal results.

How long does a leather strap last on the Rolex GMT-Master 116710BLNR-0002?

A quality leather strap (alligator, shell cordovan, or calf) typically lasts between 3 and 7 years with regular wear, depending on material and care. Shell cordovan and alligator are more durable.
