Developed as the company's flagship series, K Constantinople cymbals are crafted to emulate the handmade cymbals Zildjian produced in the early 20th Century while still in Turkey. Designed to develop a more complex character as they age, each cymbal is hand-hammered, producing unique attributes even between cymbals of the same size and model.

Constantinople Crashes are crafted with a vintage-style bell, thin weight, and pin lathing for an umbrous character with nuanced atmosphere and decay.

 Years of production: 1998-present
