Frequently asked questions

What is the lug width of the Glashütte Original Seventies 1-37-02-13-02-70?

The lug width (misura ansa) of the Seventies 1-37-02-13-02-70 is 26mm. This measurement is obtained by measuring the perpendicular distance between the inner point of one lug and the inner point of the other lug. Precise measurement is essential to avoid excessive play or unnatural tension of the strap on the wrist.

Which strap best pairs with the Seventies 1-37-02-13-02-70?

For a timepiece of this constructive level, dyed alligator (in black or dark brown) represents the ultimate choice, thanks to the patina that evolves over time. The most sophisticated alternative is vegetable-tanned calf, which develops natural, water-soluble texture with ageing. For a more casual approach, heavy-duty canvas NATO or fine-grain FKM rubber maintains vintage aesthetics without practical compromise.

How do I correctly change the strap on a Glashütte Original watch?

Changing the strap on the Seventies requires a specific tool (springbar remover). Position the watch on a stable surface, gently compress the internal spring of the springbar with the tool, and extract the bar. This procedure allows the lug to detach from the case. Repeat for the other end. Installation of the new strap follows the reverse procedure, ensuring that the springbars are fully inserted into the holes.

Are aftermarket 26mm straps compatible with the Seventies 1-37-02-13-02-70?

Yes, any artisanal strap with 26mm lug width is compatible with the Seventies, provided that the lug width matches exactly (26mm precisely). Milano Straps offers a specialised collection of 26mm straps in noble materials (alligator, calf, shell cordovan) with finishes in steel or gold, all ready for shipment and customisable according to aesthetic and functional requirements.

How long does a natural leather strap typically last on a luxury watch?

A high-quality artisanal leather strap, used in normal conditions (not exposed to excessive sweating or water immersion), has an average lifespan of 3–5 years. Vegetable-tanned leather ages more visibly but maintains structural integrity longer. Dyed alligator, due to fibre density and compactness, can exceed 7 years. Factors such as ambient humidity, frequency of wear, and maintenance (gentle cleaning, occasional conditioning) significantly influence longevity.
