Strap for Terrasport I Black / Bracelet

The lug width of the Mühle Glashütte Terrasport M1-37-34-MB is 22mm. This dimension is specific to this model and allows for the fitting of compatible straps of this exact width. The measurement should be taken between the two inner sides of the case, at the point where the strap is inserted onto the spring bar.

For the Terrasport M1-37-34-MB, we recommend straps in superior Tuscan vegetable tanning: a Moro calf or vintage tobacco leather develops a natural patina that enhances the character of the Mühle Glashütte. Alternatively, shell cordovan represents the premium choice for durability and aesthetics over time. For sports use, vulcanised rubber or NATO canvas straps are suitable.

To change the strap, use a spring bar tool (a specific tool for removing metal bars). Position the tip of the tool in the small lateral hole of the spring bar, push gently to release the internal spring, then slide the bar out. Insert the new 22mm strap by aligning the lug to the case slots, then reinsert the spring bar and verify that it is securely fastened.

Yes, the Terrasport M1-37-34-MB accepts third-party straps of 22mm width. Always verify that the dimension is exact: even 1mm of difference compromises the fit. Using high-quality artisanal straps ensures longevity and comfort. Milano Straps offers a curated selection of 22mm straps in vegetable tanning, shell cordovan, rubber and NATO fabric.

The lifespan of a leather strap depends on usage and maintenance. A vegetable-tanned calf, if worn regularly (4-5 days per week), has an estimated life of 3-5 years before visible signs of wear. Shell cordovan, thanks to the density of horse rump leather, can last 8-10 years. Regular maintenance (cleaning with a damp cloth, annual conditioning with specific balms) significantly extends longevity.
