FAQ

What is the lug width of the Glashütte Original Sixties 1-39-34-22-32-04?

The lug width of the Glashütte Original Sixties 1-39-34-22-32-04 is 18mm. This measurement is calculated as the internal distance between the two attachment pins of the lug guide inside the case lugs. It is essential to measure this dimension accurately before ordering an aftermarket strap to ensure secure attachment and proper aesthetic alignment with the case.

What strap is recommended for the Glashütte Original Sixties?

For the Sixties, the ideal strap is alligator with vegetable-tanned leather of exceptional quality, which reflects the Saxonian rigour through the natural geometric texture of the skin. A valid alternative is calf leather with a patina that evolves over time. For sports configurations, NATO straps in heavyweight canvas (grey-blue tones) or vulcanized FKM rubber straps maintain functional coherence. Your choice depends on use context and maintenance preferences.

How do I change the strap on the Glashütte Original Sixties?

Strap replacement is performed by removing the two spring bars that anchor the strap guide to the case lugs. Use a spring bar removal tool to apply gentle inward pressure, releasing the bar without damaging the case. Once the bars are freed, the old strap slides away. Insert the new strap, ensuring that the spring bars are perfectly aligned with the lug holes before pushing until they lock. If you have any doubts, Casati Milano offers bespoke consultation at the atelier.

Can I use an aftermarket-compatible strap with the Sixties 1-39-34-22-32-04?

Yes, any strap with an 18mm lug width is mechanically compatible. However, it is important to consider aesthetic harmony: the Sixties possesses a marked stylistic identity that requires materials and colours that respect Saxonian geometric language. Milano Straps offers a curated selection of 18mm straps specifically designed for watches in this category, guaranteeing both technical compatibility and aesthetic coherence.

How long does a leather strap last on the Glashütte Original Sixties?

The lifespan of a leather strap depends on the quality of the tanning, frequency of use, and environmental conditions. An alligator or calf strap of exceptional quality, with regular maintenance (cleaning and conditioning every 6–12 months), maintains structural integrity for 5–7 years of daily wear. Factors such as prolonged humidity exposure, salt perspiration, and direct sunlight accelerate fibre ageing. The patina that develops over time, however, represents an aesthetic merit if managed consciously.
