Strap for Teutonia II Kleine Sekunde Silver / Bracelet

The lug width of the Mühle Glashütte Teutonia M1-33-45-MB is 20 millimetres. This measurement describes the internal distance between the two pins that hold the strap on the watch's lugs. You can verify this by measuring horizontally between the pins using a digital calliper when the watch is unstrapped. This dimension ensures compatibility with all 20mm artisanal straps available on Milano Straps.

There is no universal choice, but rather selections coherent with the watch's identity. To preserve the Swabian rigour of the Teutonia, we recommend medium-grain alligator with vegetable tanning: the granular texture dialogues elegantly with the satin-brushed case surface. Black polished calf leather offers maximum formality, whilst a hard-weave NATO restores the instrumental vocation. For humid environments, an FKM rubber strap maintains aesthetic rigour with functional practicality. Selection depends on your context of use and tactile preferences.

Strap change requires a dedicated tool: the spring bar tool. Procedure: (1) position the watch stably on a soft surface, (2) locate the small hole on the lug at 6 o'clock, (3) insert the flat tip of the spring bar tool into the hole until you feel gentle pressure, (4) the internal pin retracts, allowing you to extract the strap, (5) insert the new strap into the lugs and ensure the pins click into position with an audible click. Do not use screwdrivers or inappropriate metal objects: you may damage the case.

Yes, completely. All 20mm straps from Milano Straps are compatible with the Mühle Glashütte Teutonia M1-33-45-MB, as the lug width is precisely 20 millimetres. Our straps are available in different materials—alligator, calf, shell cordovan, NATO, rubber—and require only a standard spring bar tool for reassembly. No mechanical adaptation is necessary: insertion is immediate. Consult our catalogue filtered by 20mm.

The lifespan of a leather strap depends on the tanning, daily use, and environmental conditions. An alligator or calf with vegetable tanning, if worn regularly, maintains structural integrity for 3–5 years with visible but functional wear. Natural leather is not an immortal material: it develops patina, surface cracks, and thinning in the buckle contact area. This process is aesthetic and manageable: periodic strap replacement is part of the nature of a mechanical instrument. An FKM rubber strap typically lasts 5–7 years with less visible degradation. Regular maintenance—cleaning with a damp cloth, rapid drying, storage in a dry environment—significantly extends useful life.
