Ahoi 562— lug 18mm

The Nomos Glashütte Ahoi 562 features a lug width of 18 mm. This measurement is taken internally between the mounting pins and represents the interior diameter of the lug seat. A compatible strap must fit precisely to this width to ensure mechanical stability and visual coherence with the 36.30 mm case proportions.

We recommend natural leather straps tanned using vegetable tanning methods, authentic alligator, or shell cordovan for formal occasions. For robust daily wear, a tightly woven NATO fabric offers versatility and durability. FKM rubber is ideal if you intend to fully exploit the 100-metre water resistance in aquatic environments. Your choice depends on your context of use and whether you prioritise elegance or functionality.

Strap replacement is achieved by extracting the lateral spring bars. Use a dedicated tool, a small watchmaker's lever, to compress the internal spring and release the pin from its seat. Proceed gently to avoid scratching the case. Once the pin is freed, the old strap can be removed. To install the new 18 mm strap, align the strap holes with the lug seats and reinsert the pin until it clicks and locks fully.

Yes, any strap manufactured with precision for an 18 mm lug width is compatible with the Ahoi 562, regardless of manufacturer. It is essential to verify that the internal width is exactly 18 mm to avoid unwanted gaps or excessive tension on the lugs. Bespoke artisanal straps guarantee maximum fit and durability over time.

The lifespan of a leather strap depends on intensity of wear, climate exposure and maintenance. A vegetable-tanned calf leather, worn daily and properly cared for, achieves 3-4 years of longevity. An authentic alligator, due to its denser fibrous structure, can exceed 4-5 years. The patina that develops over time is desirable and imparts character to the strap. Regular conditioning and periodic rest significantly extend useful life.
