Yes do send it back to Citizen, in my experience the customer service is excellent. I had to send my Auto-Zilla back to them after a service because it was not right, they have sent it to a specialist watch maker on my behalf to make sure it is right this time. Do it right and get a repair with a guarantee, good customer service is important to Citizen that's why I use them.I thought you were sending it to Citizen.
Just my two penny's worth.
