Strap for Rolex GMT-Master 16700

The Rolex GMT-Master ref. 16700 features a lug width of 20 millimetres. This standard measurement, common to GMT-Master models from the pre-ceramic era (from ref. 1675 to ref. 16710), is the fundamental parameter for identifying compatibility with any aftermarket strap. To verify the width, measure perpendicularly across the lug, excluding the terminal lugs: the result will be precisely 20 millimetres.

The ideal strap depends on usage and personal aesthetic preferences. For a conservative style, we recommend black or dark cognac alligator, which contrasts elegantly with the anodized bezel. For those who appreciate aesthetic evolution over time, bordeaux-mahogany shell cordovan develops extraordinary patina after a few months. Vegetable-tanned calf represents a compromise between initial softness and durability. For sports contexts, a dark grey NATO maintains the watch's instrumental spirit without visual heaviness.

The procedure requires two specific tools: a spring bar tool and optionally a magnifying glass. Position the 16700 on a soft surface (felt or cotton cloth). Insert the tip of the spring bar tool into the lower lug hole and press gently upward until the spring is released. Withdraw the old strap. Repeat the operation on the upper lug. When inserting the new strap, align the terminal and use the tool to compress the spring until it clicks into place. Verify that the spring is fully seated in the watch's lug grooves.

Yes, any strap with a 20 millimetre lug width is fully compatible with the 16700. Compatibility depends solely on lug width, not on material (alligator, calf, shell cordovan, rubber, NATO). We recommend verifying that the strap is produced with artisanal craftsmanship and that the terminals are made of stainless steel to prevent premature wear of the watch's lug holes. Casati Milano straps, crafted bespoke, guarantee millimetre precision in the terminals.

Durability depends on leather quality, usage conditions, and maintenance. A quality alligator or calf strap, with traditional tanning, maintains structural and aesthetic integrity for 3-5 years of daily wear. Shell cordovan, being more robust, can exceed 7-8 years. Frequent exposure to humidity, perspiration, and UV rays accelerates aging. To extend lifespan, avoid prolonged contact with chlorinated water, expose the strap to direct sunlight only during desired ageing, and clean periodically with a damp cloth. An artisanal Casati Milano strap, crafted with vegetable tanning, retains aesthetic beauty even after heavy use due to natural patina development.
