When a watch is purchased, our watchmaker will perform a thorough inspection of the movement and perform a number of tests to ensure the watch is functioning in top condition before shipping. This process can take 7-10 business days. 

Once your watch is ready, watches shipped within the United States are sent via insured FedEx Overnight and will arrive the next day. We will send over tracking information once the watch ships. 

International shipping can take a number of days considering customs and travel. Straps made from exotic materials banned for import will be removed from the watch prior to shipping.

We know it can be difficult be completely certainly that a watch's condition, size or shape is what you are looking for. 

We provide a 5 day inspection period from delivery so that you may receive the watch and decide if it is right for you. 

This is not a trial period; our watches are well documented and any wear or damage will be deducted from the return amount. 

The Keystone offers a one-year warranty covering all mechanical aspects of the watch. This includes abnormal time keeping relative to the watches age, battery replacements and general mechanical issues inside the watch. Many of the watches we sell are vintage and thus may gain or lose more time than modern specifications. We reserve the right to use our discretion and experience to determine acceptable time keeping for vintage watches.

At The Keystone, we accept payment via Credit Card, Bank Transfer and major Cryptocurrency Coins. Please reach out via email with any questions about payment to Hello@thekeystone.com
