Strap for Rolex GMT-Master 116718LN

The lug width of the Rolex GMT-Master II 116718LN is 20mm. This is the standard dimension for straps compatible with this sports watch. Always verify the case diameter (40mm) and lug width before purchasing an aftermarket strap.

The ideal strap depends on usage and personal preference. For the two-tone variant with green/black bezel (Hulk), we recommend black or dark brown alligator to emphasize sportiness, or shell cordovan for a more elegant touch. NATO straps offer colour versatility and ease of change.

The strap is replaced by removing the spring bars (lugs) from the case ends with a dedicated tool. The 116718LN features solid lugs, not an integrated deployante clasp. We recommend entrusting this to a professional to avoid scratching the yellow gold case. Casati Milano offers this service in-atelier.

Yes, provided they respect the 20mm lug width. Artisanal straps of superior quality, made with vegetable-tanned leather or alligator, are fully compatible and often offer greater personalisation than original Rolex straps.

A high-quality natural leather strap lasts on average 3-5 years with daily use, depending on sun exposure, humidity and maintenance level. Casati Milano straps guarantee 18 months against manufacturing defects. The patina that develops over time is part of the character of natural leather, not a flaw.
