Strap for Seventies Chronograph Panorama Date Turquoise / Alligator / Folding

The lug width of the Glashütte Original Seventies is 26mm. This measurement, which is not a standard size, corresponds to the distance between the centres of the two spring bars that connect the strap to the case. It is essential to verify that your chosen strap is specifically designed for this width to ensure perfect alignment with the case lugs.

For the Seventies 1-37-02-15-02-50, straps in alligator with vegetable tanning (cognac brown or black), aged calf leather with medium grain, or thick cotton NATO in grey or sand beige are recommended. Alligator emphasises the squared geometry of the case, whilst calf develops a fascinating patina over time. FKM rubber remains ideal for more dynamic or sporting use.

To change the strap, obtain a spring bar tool to remove the bars from the case without damage. Position the tool on the internal spring of the bar and push gently, then extract the bar. Insert the new strap by aligning the holes with the lugs, then reinsert the bar until it clicks into place. For risk-free workmanship, consult the Casati Milano atelier, specialised in customisation services.

Yes, you can use aftermarket straps provided they are designed for the 26mm lug width. Carefully verify the technical specifications with the supplier. MilanoStraps' straps are handcrafted and available in a variety of materials (alligator, vegetable tanned calf, shell cordovan, NATO, rubber) all compatible with the Seventies' 26mm width.

A quality leather strap (alligator, calf, shell cordovan) has an average lifespan of 3-5 years with daily use, provided adequate maintenance is performed. Vegetable tanning develops a fascinating natural patina over time. Prolonged exposure to moisture and perspiration shortens durability; in such cases, it is advisable to alternate with rubber straps or use a steel deployant buckle to distribute stress.
