Strap for Sixties Square Chronograph Stainless Steel / Rock

The lug width of this model is 18mm. This dimension represents the distance between the two attachment points of the strap on the case and is critical for ensuring proper aesthetic and functional fit. Precise measurement with a digital caliper is advised before ordering an aftermarket strap.

For this chronograph, dark brown or grey tortoiseshell alligator with satin steel deployante clasp is the optimal choice. The regular texture of Mississipi crocodile leather mirrors the rationalist aesthetics of the case, enhancing Glashütte Original's original design without competing visually with the dial.

The Sixties uses standard 18mm straps with spring bars. For replacement: place the watch on a soft pad, locate the spring bars on either side of the case, gently press with a dedicated tool to release the bar, remove the old strap and insert the new one by aligning the lateral holes. Avoid excessive force to prevent compromising the case finish.

Yes, the 1-39-34-25-32-04 is compatible with any strap in 18mm lug width. Milano Straps offers a complete collection of artisanal straps in this size: alligator, shell cordovan, vegetable-tanned calf, NATO and FKM rubber, all tested for ergonomics and secure holding.

A quality leather strap, with vegetable tanning and artisanal craftsmanship, typically lasts 3-5 years with daily wear. Durability depends on frequency of use, moisture exposure and buckle wear. Alligator straps tend to last longer thanks to the dense fibrous structure of the leather.
