Frequently asked questions

What is the lug width of the Glashütte Original Seventies 2-39-47-11-12-50?

The lug width is 26mm. This measurement is specific to the 40mm cushion case and ensures optimal proportions between the watch and the strap, maintaining both aesthetic and structural stability. The 26mm represents the design equilibrium typical of Glashütte's engineering tradition, allowing for substantial straps without burdening the wrist.

What is the most suitable strap for the Glashütte Original Seventies?

For the Seventies, the ideal strap depends on usage and aesthetic preferences. A dark brown or black alligator maintains the watch's formal sobriety, whilst shell cordovan develops natural patina over time. For versatility, vegetable-tanned calf leather in neutral tones is excellent. Should you prefer a more sporty and historically accurate approach, a navy or grey NATO remains faithful to the Seventies heritage.

How do you change the strap on the Glashütte Original Seventies 2-39-47-11-12-50?

Strap replacement is performed using a spring bar removal tool. Insert the tool into the lateral slot of the lug to compress the internal spring, then extract the pin. Repeat identically on the opposite side. Ensure the pins are clean before installing the new strap. If you lack experience, consulting a certified watchmaker is advised to prevent scratches to the case.

Are Milano Straps' 26mm straps compatible with the Glashütte Original Seventies?

Yes, absolutely. All straps in the 26mm collection from Milano Straps are engineered to fit the Seventies 2-39-47-11-12-50 perfectly. Compatibility is ensured through rigorous material selection—alligator, shell cordovan, calf, NATO, and rubber—and precise construction of the attachment points. You can customise your choice online according to chromatic preferences and intended use.

How long does a leather strap last on the Glashütte Original Seventies?

The lifespan of a leather strap depends on usage, material quality, and maintenance. Premium alligator or shell cordovan, worn daily, maintains structural integrity for 4–6 years. Natural leather develops patina and grain, becoming softer and more adapted to the wrist over time. To extend longevity, avoid prolonged exposure to moisture and perspiration, periodically clean with a damp cloth, and store in a temperate environment. Vegetable-tanned calf straps tend to age more visibly, acquiring character and authenticity.

Does the Glashütte Original Seventies 2-39-47-11-12-50 arrive with an original strap?

Typically the Seventies is supplied with a stainless steel bracelet featuring a deployante clasp. However, many collectors prefer to replace it with leather for formal wear or NATO for sporting versatility. The 40mm cushion case accommodates any 26mm strap flawlessly, permitting considerable customisation freedom without structural compromise.
