This watch has a new battery as of May 2024. This watch is able to tell accurate time. This watch does alarm after 15 seconds past the alarm set time however this watches day and date function does not appear to be able to advance. I am unsure why the day and date function does not advance but again as stated previously this watch does tell accurate time to the minute and Once activated, the alarm function works perfectly fine. It is the responsibility of the buyer at their choosing to fix any issues with the advancement of the day and date function on the watch dial. I personally would only use this watch to tell accurate time and have an alarm. I sell for my son’s medical and childcare needs. I accept returns and REASONABLE offers. Unless otherwise stated it is the responsibility of the buyer to maintain any parts or pieces of any mechanical items sold including adding or replacing batteries periodically for items that run on batteries. Please help me help my family. I have many other watches and items not listed yet so ask me to check my inventory. It is very hard to balance being a father and working to list but I promise I have many other items I just don’t have the time to list yet. I combine shipping on request. If you are a returning customer please message me as the new form of managed payments makes it hard for me to tell if you have come back.
