The A. Lange & Söhne 1815 Tourbillon Platinum takes a 20 mm strap: measure between the lugs and that is the only number you need. We list 1,170 straps in that width. With a 39.5 mm case, a strap of medium thickness keeps the balance. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
We do not sell watches. This page exists to find the straps that fit this one.
