Strap for Tangomat Glück Auf

The Tangomat 641.S1 features a lug width of exactly 20 mm, measured centre-to-centre between the pins (lugs) that hold the strap. This dimension is standard for the model and allows no variance: it ensures visual proportionality with the 38.30 mm case and correct mechanical stress distribution.

Given the Bauhaus philosophy of the Tangomat, we recommend straps in vegetable-tanned leather with fine grain (calf) or alligator with natural tanning. For those seeking minimalism, a cotton or technical-fabric NATO maintains aesthetic coherence. Avoid ornamental straps or those with exaggerated polished finishes: the Tangomat demands geometric sobriety.

The strap is replaced by releasing the two lateral lugs using a dedicated tool (spring bar tool). Insert the tool tip into the small recess beneath the lug to compress the internal spring, extract the old strap, and insert the new one. A straightforward operation requiring approximately 2 minutes per side. We recommend performing the operation on a soft surface (mouse pad, cloth) to prevent scratches.

Yes, any strap with a 20 mm lug width is compatible. Milano Straps offers a curated selection of artisanal straps in this measurement, manufactured in Italy at the Casati Milano atelier: vegetable-tanned leather, alligator, shell cordovan, technical fabric. All straps are ready for shipment and customisable for lug diameter and wrist length.

A quality leather strap, subject to rotation and periodic maintenance (cleaning with a soft cloth, annual hydration with neutral balm), maintains structural integrity for 5–8 years. Natural patina develops progressively, imparting character. Shell cordovan and alligator, by virtue of superior material density, may exceed 10 years. Determining factors: frequency of use, ambient humidity, skin perspiration.
