The first very important thing to figure out is what caliber movement are you trying to set, a lot of people get frustrated when attempting to set their watch because they were using the wrong set of setting instructions.
Citizen released 2 versions of the Blue Angels Skyhawk, the only difference is one is titanium and the other stainless steel, both have very similar model numbers: JY0040-59L and JY0050-55L. The same caliber movement was used in both models, which is the caliber U60 atomic timekeeping movement.
NOTE: The watch must be able to detect radio waves during setting.
Citizen provides excellent and easy to follow setting instructions on their website, simply go to http://citizenwatch.com
confirm your location, input your watch model in the search box located in the header section of the site, in this case we are searching for Skyhawk. Select your timepiece from the search results and click on the setting instructions link located below the image of the watch. There is a .pdf version and a video clip I would recommend to familiarize yourself with both. We're here to help, if you encounter any difficulty along the way give us a call at (212) 840-0441, or visit our website http://www.watchrepairny.com/our-services/
