Strap for Tetra² Tausendgüldenkraut

The Tetra 459 features an 18mm lug width, a non-standard measurement that reflects the geometric proportions of the 29.50mm square case. This lug width is a distinctive characteristic specifically engineered to maintain visual balance with the watch's compact diameter.

For the Tetra 459, alligator or vegetable-tanned calf leather straps emphasise the geometric simplicity of the case. Cotton-nylon NATO straps offer sporting versatility whilst maintaining aesthetic rigour, whilst butadiene rubber ensures daily practicality. Selection depends on intended use and preferred colourway: cognac and walnut brown for elegance, grey or blue for modernity.

The Tetra 459 uses a non-standard 18mm lug width. To change the strap, remove the lateral spring bars positioned at the case extremities using a dedicated tool (spring bar remover). We recommend this operation at a specialised atelier such as Casati Milano to ensure the stainless steel case remains scratch-free.

No. The Tetra 459 specifically requires 18mm lug width straps. Using different measurements (16mm, 20mm) would cause damage to the spring bars or case. 18mm straps are available in various finishes and materials from specialised suppliers such as milanostraps.it, offering extensive choice in colours and textures.

A quality vegetable-tanned leather strap, worn daily on a Tetra 459, has an estimated lifespan of 18 to 36 months, varying based on climate, humidity and frequency of use. Aniline leather develops a unique patina over time, whilst butadiene rubber offers greater longevity (36-48 months) with less aesthetic evolution. Regular maintenance extends useful life.
