Strap for Seventies Chronograph Panorama Date Turquoise / Nubuck / Folding

The lug width (ansa width) of the Seventies 1-37-02-06-02-55 is exactly 26 millimetres. This uncommon width was deliberately selected by Glashütte's design team to emphasise the proportion of the 40mm case and create a suspended visual balance. Always verify the distance between the lug pins (spring bars) to ensure precise compatibility with an aftermarket strap.

The ideal strap depends on usage and aesthetic preference. An alligator in chocolate or cognac tones amplifies the notion of uncompromising noble material. Vegetable-tanned calf leather offers natural patina and authentic ageing. For daily wear, FKM rubber or cotton NATO straps guarantee constructive robustness. Consult our collection of 26mm straps to evaluate all available options tailored to your requirements.

The strap is replaced by extracting the two spring bars located at the lug ends. Use a dedicated tool or small screwdriver to depress the internal spring mechanism, then slide out the old strap. Insert the spring bar into the hole of the new strap and allow the spring to close securely. We recommend entrusting this operation to a qualified watchmaker to prevent damage to the case.

Yes, our collection includes bespoke high-quality straps specifically manufactured for the 26mm lug width. We utilise noble leathers (alligator, vegetable-tanned calf, shell cordovan) and technical supports in satin-finished stainless steel, FKM rubber, and premium textiles. Each strap is available for rapid dispatch and can be customised according to your preferred chromatic tones and finishes.

The lifespan of a leather strap depends on leather quality and intensity of use. An alligator or shell cordovan strap worked with vegetable tanning lasts approximately 3–5 years with daily wear. Mid-range calf leather achieves 2–3 years. Longevity increases substantially with rotation between multiple straps and periodic maintenance (gentle cleaning, protective treatments). Rubber or NATO straps demonstrate superior durability in humid environments and require minimal maintenance.
