Strap for Seventies Chronograph Panorama Date Yellow / Nubuck / Folding

The lug width of this model is precisely 26 millimetres, a specific dimension that reflects the proportions of the 40mm cushion case and its approximately 15.5mm height. This measurement is unconventional in the contemporary luxury chronograph market, therefore requiring a bespoke strap to ensure correct visual alignment with the lugs. You can verify the exact measurement of your example using a digital calliper, measuring the internal distance between the lug attachment holes.

Alligator remains the most refined choice, with its fine and consistent grain reflecting light subtly without competing visually with the degradé dial. Vegetable-tanned calf leather is ideal if you desire more pronounced texture that develops patina over time. For a sportier, more casual approach, silk ramie NATO straps or FKM rubber offer versatility across contexts. Your choice depends on intended use: alligator for formal occasions, calf for refined daily wear, rubber for technical environments or warm seasons.

The strap attaches to the stainless steel deployant via two spring bars positioned in the lugs. To change: place the watch on a soft surface (rubber mouse pad); use a dedicated spring bar tool to gently compress the bar, creating space to remove one strap end; repeat on the other bar. During this operation, take care not to scratch the case. Once removed, your new 26mm strap simply inserts by pushing the spring bars into the holes until they click into place. If you lack experience, professional assistance from Casati Milano atelier is recommended to prevent damage.

Your timepiece requires 26-millimetre lug width straps, a dimension that excludes the vast majority of universal aftermarket options. Milano Straps specialises in a curated collection of alligator, calf, NATO and rubber straps specifically manufactured in the 26mm size. All our straps are compatible with the original Glashütte deployant and available in diverse colour variations. We advise against using 24mm or 28mm straps, as they would create aesthetic and structural inconsistencies.

Leather strap longevity depends on leather quality, tanning methodology, and intensity of use. High-quality vegetable-tanned alligator leather (as supplied by Milano Straps) typically lasts 4–6 years under daily wear conditions with standard maintenance. Vegetable-tanned calf leather develops patina more rapidly but acquires compelling character within 12–18 months. Synthetic fibre NATO straps offer superior durability (7–10 years). To extend your strap's useful life: avoid prolonged saltwater exposure, periodically apply neutral conditioner, and store in a dry environment. If your strap shows structural compromise (deep cracking, inner lining separation), replacement is advisable.
