Strap for Tetra² Hasenohr

The lug width of the Tetra 463 is 18 mm. This width is specific to maintain optical proportions with the 29.50 mm case diameter. Measure with callipers the internal distance between the case lugs to verify accuracy.

The best strap depends on usage and aesthetic preference. For pure elegance, alligator in vegetable tanning in dark brown dialogues perfectly with the brushed case. For versatility, bourbon calf develops a fascinating patina over time. For sportiness, a dark grey NATO or FKM rubber strap maintains the essential geometry of the model without compromise.

Use a spring bar tool or small flat screwdriver. Locate the pins at the case extremities, apply light pressure to compress the internal spring of the pin, then extract the old strap. Insert the new 18 mm strap pins into the case lugs and secure them firmly. Verify that the strap sits level before fully closing.

Yes, provided it is an 18 mm compatible strap. Verify that the pin holes of the strap have the same internal diameter (typically 1.5–2 mm) and that the width is exactly 18 mm. A quality strap from a specialist manufacturer such as Milano Straps guarantees compatibility and durability over time.

An alligator or vegetable-tanned calf strap typically lasts 3–5 years with daily use, provided regular maintenance (light cleaning, annual conditioning). Vegetable tanning tends to age more slowly than industrial methods, developing a desirable patina. FKM rubber straps have a lifespan of 2–3 years before showing signs of UV degradation and structural wear.
