Strap for Grande Lange 1 Yellow Gold / Champagne / Bracelet

The Lange 1 Ref. 115.321 features a lug width of precisely 22 millimetres. This dimension is specific to certain Lange models and is proportioned to the 41.90-millimetre case. To verify the lug width, use a digital calliper positioned on the inner face of the spring bar, measuring the distance between the two attachment points.

For the Lange 1 115.321 in yellow gold, alligator leather represents the quintessential choice: its natural grain and patina development over time create an extraordinary dialogue with the warmth of gold. Shell cordovan is a premium alternative featuring dense fibres and elegant ageing characteristics. Vegetable-tanned calf in natural or grey tones offers minimalism and a visually stabilising effect. A deployant clasp remains the ideal closure system for this model.

Changing the strap on the Lange 1 requires careful attention given the case's delicacy and the timepiece's value. Use a spring bar removal tool, inserting the thin pin into the dedicated holes located laterally on the lugs. Gently extract the spring bar, remove the old strap, and insert the spring bar into the new strap before re-engaging it with the case lugs. If you lack expertise, entrust the procedure to a certified watchmaker.

Yes, any strap with a compatible 22-millimetre attachment fits the lugs of the Lange 1 115.321. However, the construction quality of the strap is paramount: a masterpiece of haute horlogerie deserves a strap crafted with equivalent meticulousness. Noble materials such as alligator, shell cordovan and vegetable-tanned calf, combined with precise stitching and a reliable deployant, ensure an experience worthy of the Saxon timepiece.

The longevity of a leather strap depends on daily wear, ambient humidity and construction quality. A superbly crafted alligator or shell cordovan strap, worn regularly, can last between 3 and 7 years before displaying visible signs of wear. Vegetable-tanned leather ages more rapidly, developing a desirable patina, whilst lesser-quality leathers deteriorate within 18 to 24 months. Periodic maintenance (cleaning and conditioning) significantly extends the strap's useful life.
