We stand by the quality of all of our pre-owned watches and mechanical objects. If something goes wrong, we’ll always strive to remedy the situation in a timely manner and to the best of our ability. The satisfaction and trust of our clients are of the highest importance to everyone at Greenwich Time.

All of our pre-owned watches undergo, at a minimum, non-invasive mechanical inspections to ensure they are operating correctly and to ensure that they meet our standards of timekeeping and functionality.

Our pre-owned watches, unless otherwise stated, are covered by either a full or limited twelve-month warranty. This excludes any damage or mechanical failure sustained to the watch due to improper use or an incident. Due to their age, some pre-owned watches should not be subjected to the same conditions as when new.

We are passionate about Relationships.

Here at Greenwich Time, we attempt to emulate a boutique experience online. Helping you find the perfect match for your lifestyle, taste, and needs. Building a strong community around our shared passion is the leading principle behind our small but mighty company.

We Know a thing or two about watches.

Greenwich Time has sold tens of thousands of watches over the last 4 decades. We are a small team of experienced purveyors who are all part of a large network of buyers and sellers. We have a great reputation for offering only the finest examples of watches.

We live by one cardinal rule: we only source, sell, and buy watches we would own ourselves.

We Guarantee everything we sell.

Once you purchase a watch from Greenwich Time, rest assured that you are backed by the most comprehensive warranty and Authenticity policy; you will not find a safer place to buy a watch on the internet.
