All watches are sold AS-IS and there are no guarantees or warranties since they are all USED.
They have been tested, but only for a short period of time. There could be issues that went unnoticed during the time of the testing. If unable to test the item there is a possibility of the item having an unknown defect. The functions (digital watches) work but I cannot guarantee the accuracy. Some scratches may not show up on camera. May not be waterproof.
Please take a good look at the pics to see what you are getting!
Watches that use batteries only (please disregard if you are purchasing a mechanical watch): Some of the batteries have been replaced, some have not if the watches were running when they were purchased. The watches are all running when shipped, but there is a possibility that the battery could even go out on it's way to you. It depends on how old the battery in any particular watch is. You can buy replacement batteries right here on eBay for a very low cost!!
