Tetra 485— lug 18mm

The Nomos Glashütte Tetra 485 features a lug width of 18 mm. This dimension is specific to this model and ensures proper proportions between the square case and the strap. When purchasing a replacement strap, ensure it is compatible with this width.

The Tetra 485 responds well to quality leather straps, particularly alligator or vegetable-tanned calf leather. For a sportier aesthetic, a NATO strap in cotton/nylon blend offers comfort without aesthetic compromise. Your choice should reflect intended use: leather for formal contexts, NATO for daily-casual wear.

The Tetra 485 is fitted with standard spring bars. Use a dedicated spring bar tool to extract the bars from the lugs at case ends. Push each bar toward the centre, then remove the old strap. Insert the new strap, ensuring the spring bars click firmly into position. If uncertain, consult a professional to avoid case damage.

Yes. Any strap with an 18 mm lug width—including aftermarket options—is compatible with the Tetra 485. We recommend selecting specialised manufacturers who guarantee precision in construction and finishing, to preserve the minimalist aesthetic and build quality of your watch.

A quality leather strap typically lasts 2–4 years of daily wear, depending on tanning method (vegetable-tanned leather lasts longer) and environmental humidity. NATO straps have superior durability, lasting 5–7 years. Replacement is straightforward and advisable when leather shows evident wear or the buckle no longer secures firmly.
