My uncle was a professional triathlete who was sponsored by Oakley. He gifted this watch to my dad. My dad has since passed away and I would like to get this watch working. The watch is in super good shape making me believe that the battery is just dead. I am not mechanically inclined when it comes to watch’s and I know absolutely nothing about them. I browsed online and couldn’t find any videos showing how, and reading another threads people said the battery replacement is complicated. Is there a specific battery size for the bullet watch? Or can I send it in to someone? I’m in the Vancouver British Columbia area. Thanks!
