1815 221.032— lug 19mm

The lug width of the 221.032 is 19 mm. This measurement is specific to this model and is proportioned to the 35.90 mm case diameter. When purchasing an aftermarket strap, always verify that the width is exactly 19 mm to ensure correct positioning on the lugs and harmonious aesthetics.

Alligator remains the most natural choice: its fine grain structure dialogues elegantly with the clean lines of the Saxon case and develops a patina that enhances aesthetic value over time. For those seeking softness and longevity, premium vegetable-tanned calf leather is an excellent alternative. If you desire daily versatility, a NATO strap in fine canvas offers a casual interpretation whilst maintaining the formal dignity of the model.

To change the strap on the 1815, you will need a spring bar tool (extractor). Insert the flat end of the tool into the small hole located beneath the lug, press gently to release the internal spring mechanism, and remove the old strap. Position the new strap (19 mm) aligned perfectly with the lugs and push the spring bar until it clicks into position. Avoid forcing: correct insertion should be fluid and precise.

Yes, provided the lug width is exactly 19 mm and the construction quality is impeccable. An artisanal strap crafted to luxury standards—such as those available in the 19 mm selection at milanostraps—guarantees an aesthetic and functional result consistent with the value and precision of the timepiece. We recommend selecting noble leathers (alligator, calf, shell cordovan) to maintain the constructive dignity of the Lange & Söhne.

The lifespan of a leather strap depends on leather quality, frequency of wear, and climatic conditions. A premium alligator or calf strap, worn daily, typically lasts 4-7 years before replacement is necessary. A shell cordovan strap can last 10+ years thanks to the natural density of the leather. To extend longevity, avoid prolonged exposure to extreme humidity and periodically apply protective treatment with natural waxes recommended by your craftsperson.
