Strap for Seventies Chronograph Panorama Date Blue / Calf - Folding

The lug width of the Glashütte Original Seventies reference 1-37-02-08-02-62 is precisely 26 millimetres. This measurement is taken as the internal distance between the two metal lugs of the case. A compatible strap must be exactly 26mm wide to ensure a perfect fit without play or compression. It is advisable to verify the measurement personally with a digital calliper before ordering a new strap, as this width is less standardised than the commercial 20mm, 22mm or 24mm formats.

The Seventies pairs elegantly with alligator straps (black, brown or deep blue) for formal occasions, or vegetable-tanned calf leather for versatile daily wear with a developable patina over time. For a more sporting approach, high-density polyamide or cotton NATO straps are excellent choices. FKM rubber is the ideal solution for intensive outdoor activities. The choice depends on the context of use: alligator for office wear, calf leather for versatile daily use, NATO for contemporary contrast, and rubber for superior waterproofing and grip.

To change the strap you will need specific tools: a spring bar tool or dedicated tools for 26mm lugs. Place the watch on a soft surface (watch mat), locate the small holes at the ends of each lug where the spring bar sits, and gently push with the tool to release the retaining spring. Remove the old strap, then insert the new one by aligning the holes and pressing until you hear a click. If you lack mechanical experience, it is advisable to entrust the operation to a professional watchmaker or Milano Straps to avoid scratching the case.

Yes, quality aftermarket straps manufactured for 26mm lug width are completely compatible with the Glashütte Original Seventies. Milano Straps offers a complete selection of artisanal straps in leather (alligator, calf), NATO and technical rubber, all designed to fit perfectly on 26mm lugs. Choosing an aftermarket strap allows you to personalise the Seventies according to your colour and material preferences whilst maintaining mechanical and structural compatibility. Always verify that the strap declares 26mm compatibility before purchase.

A quality leather strap (alligator, vegetable-tanned calf or full-grain leather) used daily on a chronograph like the Seventies lasts on average 3-5 years, depending on intensity of use, climatic conditions (humidity, sun exposure) and maintenance. Vegetable-tanned straps develop a natural protective patina that can extend life to 6-8 years. Technical rubber (FKM) offers superior durability (5-7 years) in humid or mechanically stressful environments. Periodic replacement is recommended to maintain comfortable fit and preserve the overall aesthetic of the watch.
