Strap for Sixties Square Chronograph Stainless Steel / Black

The lug width of the Glashütte Original Sixties 1-39-34-02-32-04 is 20mm. This measurement is determined by the distance between the spring bar pins and represents the specific standard for this chronograph model. Ensure you measure accurately with an analogue calliper to avoid compatibility issues.

Alligator leather with vegetable tanning is the most coherent choice with the historical and aesthetic identity of the Sixties: its natural grain and the patina that develops over time reflect the authenticity of Saxonian chronographs from the 1960s. For daily wear, vegetable-tanned calf or high-quality FKM rubber ensure durability and simple maintenance whilst preserving the austerity of the stainless steel case.

Strap replacement requires a spring bar tool: insert the tool's tip into the small hole of the tension spring located beneath the case and apply gentle inward pressure to release the spring, then slide out the pin. Proceed with caution, as the integrated lugs are sensitive to excessive force. We recommend professional assistance for the first replacement.

Any strap designed for a 20mm lug width is compatible with the Glashütte Original Sixties 1-39-34-02-32-04. Milano Straps offers a curated selection of artisanal straps in alligator, calf, NATO and rubber, all tested for this specific lug measurement. Guaranteed compatibility eliminates the risk of excessive play or metal deformation.

A high-quality leather strap, crafted with vegetable tanning and natural thread stitching, typically lasts 3-5 years with daily wear. Longevity depends on humidity exposure, frequency of use and climatic conditions. The patina that develops on the leather surface is not a sign of wear but rather desirable ageing. To extend durability, consider alternating straps and allowing the leather to breathe.
