Strap for Sixties Stainless Steel / Silver / Alligator / Pin

The lug width of the Glashütte Original Sixties 1-39-52-01-02-04 is 18mm. This measurement corresponds to the distance between the two lugs protruding from the case where the strap is fitted. It is crucial not to confuse this dimension with the overall strap width: an 18mm strap will fit perfectly onto the Sixties lugs without play and without being too tight.

For the Sixties 1-39-52-01-02-04, we recommend straps in fine leather such as alligator with vegetable tanning for an elegant dress aesthetic, or aged calf leather if you desire a natural patina that evolves over time. For more versatile everyday use, a NATO or FKM rubber strap with deployante offers practicality and durability whilst maintaining the sophisticated character of the watch. Your choice depends on intended use and the aesthetic tone you wish to express.

To change the strap on the Sixties, you must extract the spring bars that connect the strap to the case lugs. Using a dedicated spring bar tool, gently press the pin from one side to release the strap from the upper lug, then extract the pin. Repeat on the second side. Once the old strap is removed, insert the new strap's spring bars, aligning them with the lug holes, and press until they click into place. Ensure the spring bars are fully seated and the strap is secure before wearing the watch.

Yes, the Sixties 1-39-52-01-02-04 is fully compatible with quality 18mm aftermarket straps. However, to preserve the constructive and aesthetic integrity of the model, we recommend selecting straps made from noble materials (alligator, vegetable-tanned calf, shell cordovan) with finishes that respect the Saxon design language. Avoid low-quality straps that may develop staining or deteriorate rapidly, compromising the understated elegance of the Sixties.

The lifespan of a leather strap depends on material quality and usage intensity. A quality alligator or vegetable-tanned calf strap, worn moderately (3–5 days weekly), typically lasts 3–5 years before replacement. Extended exposure to moisture, perspiration, and temperature fluctuations accelerates ageing. To extend strap life, avoid soaking it, store in dry conditions, and occasionally apply quality leather balms. Vegetable-tanned leather develops an appreciated natural patina, whilst cordovan is more resilient and may last 5–7 years.
