The Seventies 2-39-47-12-12-50, seen from the bench

The Glashütte Original Seventies 2-39-47-12-12-50 reimagines 1970s German watchmaking aesthetics with contemporary technology. It features a 40 mm stainless steel square case with rounded corners, a panoramic dial revealing the internal mechanics, and the in-house caliber 39-47 with Trois Quarts Plate finishing. Functions include hours, minutes, seconds, and a dual-window Big Date complication. Water resistance is 100 metres. The watch band has a 26 mm lug width.

Frequently asked questions

What is the lug width of the Glashütte Original Seventies 2-39-47-12-12-50?

The lug width (strap width) of the Seventies is 26 millimetres, a non-standard dimension requiring careful strap selection. This measurement is specific to this model and not interchangeable with standard 20mm or 24mm lugs. Milano Straps offers a dedicated collection of 26mm-compatible straps.

What is the best strap option for the Seventies 2-39-47-12-12-50?

The Seventies' minimalist, geometric aesthetic pairs exceptionally well with coarse-grain alligator or vegetable-tanned calf leather. For versatility, a canvas NATO in tortoiseshell tone or an FKM rubber strap complements the squared case geometry whilst maintaining visual clarity. Choice depends on intended use: leather for formal-smart wear; NATO or rubber for casual-instrumental styling.

How do I change the strap on this watch?

The Seventies uses straight pin attachments (factory non-removable). Strap replacement requires a 26mm-compatible deployant clasp or a push-button spring bar. We recommend professional service: Milano Straps and Atelier Casati Milano provide strap-change and bespoke finishing services tailored to your specifications.

Can I use aftermarket straps compatible with the Seventies?

Yes. Any strap with 26mm lug width is compatible with the Glashütte Original Seventies 2-39-47-12-12-50, provided lug alignment is correct. Milano Straps provides a comprehensive 26mm strap collection in various materials and finishes, all tested for compatibility with watches in this category. Verify that lug width and strap thickness suit the case profile.

How long does a leather strap last on this watch?

Longevity depends on material, usage, and maintenance. A vegetable-tanned calf strap lasts 3–5 years with daily wear and regular cleaning; shell cordovan resists 7–10+ years due to fibre density. Leather naturally ages, developing patina appreciated by many collectors. Milano Straps offers restoration and re-finishing services to extend your original strap's lifespan.
