Frequently asked questions

What is the lug width of the Glashütte Original Seventies 2-39-47-12-12-06?

The lug width is 26mm. This intermediate measurement is specific to the Seventies model and requires custom-built straps. Measure the internal distance between the spring bar pins accurately to verify compatibility.

Which strap do you recommend for the Glashütte Original Seventies?

We recommend Hermès alligator (bourbon or black) for formal elegance, vegetable-tanned calf leather in medium brown for natural ageing patina, or thick cotton NATO in minimal designs for versatility. Your choice depends on intended use: formal, daily wear, or sporty.

How do I change the strap on a watch with 26mm lugs?

Use a spring bar tool (hook-type implement) to compress the spring bar. Insert the hook into the bar seat from below, push slightly upward and remove the pin. Position the new strap by aligning the holes with the lugs, then reinsert the pin whilst compressing the spring.

Can I use aftermarket straps on the 2-39-47-12-12-06?

Yes, provided they are certified for 26mm lug width. We recommend straps made with premium leather (Hermès, Schedoni, Tanneries Roux) and stainless steel finishing to ensure aesthetic and mechanical compatibility with the Seventies.

How long does a leather strap last on this watch?

A quality leather strap (alligator, vegetable-tanned calf) typically lasts 3-4 years with standard daily wear, up to 5-6 years with regular maintenance (gentle cleaning, avoiding prolonged moisture). Ageing is natural and aesthetically desirable.
