Strap for Sixties Square Chronograph Stainless Steel / Fire

The lug width of the Glashütte Original Sixties 1-39-34-24-32-04 is 18mm. This measurement represents the internal distance between the two spring bars and determines strap compatibility. The 18mm width is proportioned to the 41.35mm case diameter according to the classical geometry of the Sixties family.

The best strap depends on intended use: an alligator strap with vegetable tanning in dark brown or black enhances the vintage and formal character of the timepiece; a calf leather with progressive patina offers versatile elegance and aesthetic ageing; a NATO in military tones provides a sporty-instrumental approach coherent with the chronograph. We recommend assessing your usage context and preferred case colour.

Position the watch with the spring bars facing upward. Use a spring bar tool or small screwdriver to press inward the suspension pin, freeing it from the case lug hole. Extract the pin completely and remove the old strap. Insert the new strap aligning the holes, then reintroduce the pin by pressing until it locks. Repeat on the other side.

Yes, any strap with 18mm lug width is compatible with the Sixties 1-39-34-24-32-04. Milano Straps offers a curated selection of handcrafted leather straps (alligator, calf, shell cordovan), NATO, and rubber, all engineered to the technical and aesthetic specifications of this watch.

A quality leather strap (alligator or calf with vegetable tanning) typically lasts 3-5 years with daily wear, developing a progressive patina that improves aesthetically over time. Lifespan depends on exposure to moisture, direct sunlight, and frequency of use. A NATO strap, conversely, resists approximately 5-7 years. Regular maintenance and periodic rest of the watch extend strap longevity.
