Tetra 456— lug 18mm

The Nomos Glashütte Tetra 456 features an 18mm lug width, measured centre-to-centre between the attachment points. This width is deliberately calibrated to preserve the architectural proportions of the 29.50mm square case without disrupting visual harmony.

A calf leather strap with vegetable tanning and fine grain is ideally suited to the 456. The homogeneous texture engages harmoniously with the Bauhaus aesthetic of the case. Alternatively, a cordura NATO in subtle weight maintains aesthetic coherence whilst offering greater practical versatility.

The Tetra 456 employs spring bar attachments at the lugs. A dedicated spring bar removal tool is required to extract the two pins from the attachment points. Position the tool beneath the pin, apply lateral pressure, slide out the old strap and insert the new one. The procedure demands precision to avoid damaging the lug attachment points.

Any strap with an 18mm lug width is compatible. Milano Straps offers a dedicated collection of premium leather straps, NATO options and FKM rubber, all hand-crafted to ensure construction quality comparable to the Tetra's manufacturing standards.

A vegetable-tanned calf leather strap on a daily-wear watch such as the 456 typically lasts 3-5 years, dependent upon intensity of use and care regimen. Proper maintenance—drying, periodic conditioning—can significantly extend the longevity of the material.
