Strap for Seventies Chronograph Panorama Date Green / Rubber - Folding

The lug width of the Glashütte Original Seventies 1-37-02-09-02-63 is precisely 26mm. This measurement is taken between the two case lugs and is a specific standard for the Seventies family. To verify, position a calliper in the widest section between the two lugs: the value must correspond to 26mm.

For the Seventies 1-37-02-09-02-63, straps in alligator (with natural grain that enhances the vintage design), vegetable-tanned calf leather (for evolved patina), NATO in Cordura or silk (to emphasise the chronograph's sporty character), or FKM rubber for technical use are recommended. Shell cordovan represents the pinnacle of refinement, with extraordinary patina developing within 12-18 months.

To change the strap on the Seventies, you must remove the spring bars from the case lugs using a dedicated removal tool. Position the bar on one side of the internal spring, push carefully to compress the spring, then extract the bar. Repeat for the other side. Insert the new strap following the reverse procedure, ensuring the bars are properly seated and the strap is perfectly aligned.

No. The 26mm lug width is specific to certain models. If your watch has different lugs (for example 24mm or 28mm), the 26mm strap will not be compatible. Always verify the lug width before purchasing by consulting your timepiece's technical documentation or using a calliper.

A high-quality leather strap (alligator, vegetable-tanned calf, shell cordovan) has an average lifespan of 3-5 years with daily use and appropriate care. Longevity depends on usage frequency, exposure to moisture, and periodic application of protective balms. NATO or FKM rubber straps have greater durability, lasting up to 7-10 years, thanks to the material's resistance to external elements.
