The Sixties 1-39-52-09-02-01, seen from the bench

The Glashütte Original Sixties 1-39-52-09-02-01 embodies postwar Saxon watchmaking tradition with a 39mm stainless steel AISI 316L case and 18mm lug width. Powered by the manual-wind caliber Glashütte Original 39-52 oscillating at 28,800 vph, it features a composed dial with linear indices and stylus hands reflecting 1960s design principles. The case proportions and functional aesthetics follow Deutsche Werkbund ideals, with no superfluous decoration and a transparent caseback revealing the movement's regularity.

Frequently asked questions

What is the lug width of the Glashütte Original Sixties 1-39-52-09-02-01?

The lug width of the Glashütte Original Sixties is 18mm. This measurement is standard for the lugs on this model: any compatible strap must feature exactly 18mm width at the attachment point to fit correctly into the case lugs. Always verify the technical specifications of the strap before purchasing.

Which strap would you recommend for the Sixties 1-39-52-09-02-01?

For the Sixties, we recommend a vegetable-tanned alligator strap or European calf leather in aged brown or cognac tones. These materials reflect the minimalist and rationalist essence of the watch's Saxon design heritage. For greater versatility, a grey NATO strap or an FKM rubber strap offer durability and practicality without aesthetic compromise.

How do you change the strap on a Glashütte Original Sixties?

The Sixties employs straight lugs with internal spring bars. To change the strap: gently remove the current strap by pushing outward the tension spring located beneath the lug, extracting the lug from its housing. Insert the lug of the new strap into the same housing until the spring re-engages. Verify the lug is correctly positioned before wearing the watch.

Can I use an aftermarket 18mm strap on my Sixties?

Yes, any high-quality strap with an 18mm lug width is compatible with the Sixties. We recommend selecting materials and thicknesses that respect the case proportions: thin straps (1.8–2.0mm) appear more elegant, whilst thicknesses around 2.5mm offer greater robustness. Avoid excessively rigid straps that could stress the case lugs.

How long does a natural leather strap last on a watch like the Sixties?

A high-quality leather strap (alligator, European calf, shell cordovan) typically lasts 3–5 years under daily use, depending on humidity exposure, climate extremes, and maintenance care. The patina that develops over time is part of the natural beauty of leather. We recommend rotating straps regularly and storing them in dry environments. Periodic maintenance with specialist balms significantly extends durability.
