Strap for PanoMatic Lunar Stainless Steel / Green / Alligator / Folding

The lug width of the Glashütte Original Pano 1-90-02-13-32-31 is 20mm. This measurement is critical for ensuring perfect compatibility with aftermarket straps and must be verified by placing a calliper at the midpoint between the two lugs on the inner side of the case. An incorrect measurement could result in purchasing incompatible straps.

The ideal material depends on intended usage. For formal and classical settings, we recommend alligator in dark brown or black, which naturally complements the brushed stainless steel case. Shell cordovan in burgundy represents superior excellence thanks to its natural patina that evolves with time. For summer or everyday conditions, vegetable-tanned calf leather in beige-cream tones offers breathability whilst maintaining elegance. Cotton-nylon NATO straps are ideal for sporting contexts, whilst natural rubber remains the functional choice for humid or aquatic environments.

To change the strap, you must remove the spring bars (lugs pins) that attach the strap to the case lugs. Use a dedicated tool (spring bar tool) or an instrument specifically designed for watch servicing to gently push the small retractable internal pin of the lug. Once the pin is released, the strap slides out of the case. The reverse operation—inserting the new strap—requires correctly positioning the pin in its dedicated groove. We recommend having this operation performed by a qualified service centre if you lack experience, to avoid damage to the case or fittings.

Yes, aftermarket straps with 20mm lugs are fully compatible with the Pano 1-90-02-13-32-31. Milano Straps manufactures bespoke leather, NATO and rubber straps specifically calibrated for this lug width. It is essential to verify that the strap is fitted with exactly 20mm lugs and that the curvature of the lugs is congruent with the case geometry. Avoid manual adjustments (filing, gluing) that would irreversibly compromise the case structure.

The lifespan of a leather strap depends on frequency of wear, material quality and environmental conditions. A superior-quality alligator or shell cordovan strap, worn daily, maintains structural integrity for 4-6 years before showing significant failure. Vegetable-tanned calf tends to age more rapidly (2-4 years) towards golden tones, but this does not compromise functionality. Prolonged exposure to sunlight, moisture or perspiration accelerates degradation. To extend strap life, we recommend periodic maintenance with leather-specific creams and storage in a controlled environment when not worn.
