Strap for Terrasport III Cream / Strap

The Mühle Glashütte Terrasport M1-37-87-LB features a lug width of 18 millimetres. This dimension is specific to the model and requires dedicated watch straps. To verify compatibility, measure the space between the two lugs using a digital calliper, positioning it at the contact points between lug and case.

The Terrasport M1-37-87-LB pairs exceptionally well with straps in alligator or vegetable-tanned calf leather, which reflect the discreet proportions of the 34mm case. A nocciola brown alligator or satinised black calf create material consonance with the brushed steel. For technical solutions, Cordura canvas NATO or structured rubber maintain the functional aesthetic of the model.

Insert a flat tool (spring bar tool) under the lug, locating the small hole or release point present. Press gently to relax the lug spring, extract the pin and free the previous strap. Repeat the operation on the opposite lug. Position the lugs of the new strap by aligning the holes, reinsert the pins with the spring bar tool until the security click is heard.

Yes, any aftermarket strap with an 18mm lug width is compatible with the M1-37-87-LB. Verify that the lug width is indeed 18mm and that the material thickness does not exceed the constructive tolerances of the case. Custom straps from Casati Milano are precisely calibrated for this dimension and guarantee fitting without play.

An alligator or vegetable-tanned calf strap, worn daily with proper care (avoiding prolonged moisture and direct sun exposure), maintains functionality and aesthetics for 3–5 years. The patina that develops over time is a desirable characteristic, a sign of conscious use. Rotating with alternative straps significantly extends the life of each solution.
