Strap for Teutonia Sport II Black / Strap

The lug width of the Mühle Glashütte Teutonia M1-29-73-NB is 20 mm. This measurement represents the internal distance between the two lugs fixed to the case and determines the width of the strap you can install. To verify it, remove the current strap and measure the available space between the lugs: 20 mm is the standard for this model.

For the Teutonia M1-29-73-NB we recommend a vegetable-tanned alligator strap, which dialogues perfectly with the satinised finish of the steel case. Alternatively, an oil-waxed calf leather offers controlled texture that amplifies the industrial aspect of the watch. For versatility, a synthetic fibre NATO strap remains practical and elegant; a structured FKM rubber adds contemporaneity without betraying the Saxon heritage of the design.

Changing the strap on the Teutonia M1-29-73-NB is straightforward: two small screws at the ends of the lugs fix the spring bars to the case. Use a bottle opener or a small flat-head screwdriver to unscrew them. Once the screws are removed, the spring bars will come off easily; you can then insert the new strap. The operation takes less than a minute and requires no specialised tools.

Yes, the Teutonia M1-29-73-NB is fully compatible with 20 mm aftermarket straps. The spring bars accommodate straps up to a maximum thickness of 4.5 mm. You can choose between leather (alligator, calf, shell cordovan), NATO fabric, FKM rubber, or elastic bands. Full compatibility allows you to change the watch's appearance according to seasons and occasions.

The lifespan of a leather strap depends on the quality of the material and usage patterns. A high-quality vegetable-tanned alligator or calf strap can last 3–5 years of daily wear. A shell cordovan strap, thanks to its inherent durability, can reach 7–10 years. Exposure to moisture and perspiration reduces longevity; direct sunlight exposure accelerates ageing. Rotating between multiple straps significantly extends the life of each one.
