Unrivaled Selection

Sky Diamond Co is not a marketplace; we own every watch that we sell. This allows us to implement a true global quality standard. As one of the largest buyers of pre-owned watches in New York City, our selection is ever-changing, with thousands of pre-owned watches from the best brands available at any given time, all of which are inspected and brought to “mint” condition, ensuring exceptional quality.

Guaranteed Authenticity

We are committed to the integrity of the luxury watch industry. Our pre-owned watches are evaluated, authenticated, and brought to manufacturer operating standards without compromising value or provenance, before entering our curated inventory of pre-owned watches for sale.

Superior Watchmaking Service

Our in-house team of Swiss-trained watchmakers, technicians, and refinishers are among the most highly regarded in the industry. They assess every watch before it is presented for sale according to a rigorous quality control process, and are also qualified to address any of your watch repair needs. Every pre-owned watch we sell is backed by a 5 year Sky Diamond Co Global Warranty, and we also offer additional coverage options.
