Strap for Rolex Submariner 116613lb

The Rolex Submariner 116613lb features a lug width of 20 mm. This measurement refers to the distance between the inner shoulders of the case at the spring bar seat location. It is crucial to measure precisely before ordering an aftermarket strap, as a 19 mm strap would be loose, whilst a 21 mm strap would be impossible to install. Use a digital calliper or a metal ruler to verify the exact width of your lug holes.

For the 116613lb, characterised by its two-tone yellow gold and steel composition, the finest strap option is black alligator or brown/burgundy shell cordovan. Black alligator maintains the watch's formal character and creates an elegant pairing with the yellow gold case; shell cordovan in dark tones (cognac brown or burgundy) produces a sophisticated visual effect and develops a natural golden patina over time. Both materials are sufficiently rigid to support the case weight and offer a level of craftsmanship consistent with the watch's value.

To change the strap on your Rolex Submariner 116613lb, you will require a spring bar removal tool. Position the watch on a soft, stable surface, insert the flat tip of the tool into the spring bar access hole, gently push inward to release the spring clip and allow the old strap to drop away. Repeat on the opposite side. To install the new strap, align the lug terminals with the case's lug holes, push the spring bars into position until they snap into place. Should you lack confidence in this procedure, entrust the task to a qualified professional to avoid potential damage to the case.

Yes, any quality strap featuring a 20 mm lug width is entirely compatible with the Rolex Submariner 116613lb, provided that the terminals—the two projections that insert into the case's lug rings—are precisely 20 mm. Select straps manufactured by specialist ateliers that guarantee millimetre-precise tolerances and premium materials (alligator, shell cordovan, vegetable-tanned calf). Avoid generic straps from mass-market e-commerce platforms that do not provide detailed technical specifications regarding lug width.

The longevity of a leather strap depends on material quality and frequency of use. An artisanal-grade alligator strap will endure between 5 and 8 years of regular wear, as the hide is naturally resilient and its scale structure resists mechanical stress effectively. Shell cordovan is even more durable (8–12 years) thanks to its superior density. Vegetable-tanned calf, more sensitive to moisture, will typically last 3–5 years. Regardless of material, the strap will age gracefully, developing natural patina, surface creasing, and colour shifts—hallmarks of beauty rather than deterioration. An 18-month warranty covers manufacturing defects; thereafter, the strap can be reconditioned by an experienced craftsman.
