Strap for Tetra plum See-Through

The lug width of the Tetra 488 is 18 mm. This dimension was specifically chosen to maintain balanced proportions with the square case measuring 29.50 mm in diameter. To verify strap compatibility, measure the distance between the two lateral lugs of the case using a digital calliper.

For the Tetra 488, we recommend straps in alligator with fine grain and warm colouration, vegetable-tanned calf leather, or NATO cotton webbing. Alligator offers elegant textural contrast, vegetable-tanned calf develops a natural patina dialoguing with the case's brushed finish, whilst NATO webbing preserves the Bauhaus constructivist character of the model.

Strap replacement is accomplished via the spring bar pins positioned at the case lugs. Using a strap removal tool, gently press the pin towards the case centre until the elastic ring is released, then withdraw the old strap. Insert the new strap by aligning the pin with its seating and allowing the elastic ring to snap into position.

Yes, any strap with an 18 mm lug width is 100% compatible with the Tetra 488. Compatibility depends solely on the measured width, not on the strap's brand. Always verify that the width is precisely 18 mm to prevent excessive tension on the passant.

Leather strap durability depends on usage intensity and climate. Under normal conditions, a quality artisanal alligator or calf strap typically resists 3-5 years before showing evident signs of wear. Vegetable-tanned leather ages naturally, developing an appreciated patina. A NATO cotton strap generally lasts 5-7 years with minimal visible deterioration.
