New Citizens Bluettoth Watch

I bought this watch a few days ago. It is a remarkable product but there are shortcomings - size, inability to remain paired with iPhone, and battery drain. It is also a rather large watch that could become cumbersome when wearing. Besides these shortcomings it is in the same class as other Citizen eco watches

Bluetooth connection ( New Device)

I got this watch for Christmas from my wife. I went over the instruction manual to the best of my knowledge. Seemed to be working fine. I connected the Bluetooth to my first phone, which was the Samsung S7 Edge. I had no problem with connecting to its Bluetooth. As weeks went by the Bluetooth would go in and out and lose signal. I've emailed the company, asking for any kind of suggestions on what to do. They sent me the instruction guide video. I've watched the 22 minute video 4 times, having to pause and repeat. Not once does it go over how to connect the actual watch to a Bluetooth device. With me having an upgrade with my mobile provider, I factory reset my old phone, thinking it would be as simple as going to my new phone, to Bluetooth and reconnecting it to my new phone. I have yet to figure out how to do it. I've now had the phone for a little over 3 weeks and still no help on getting it fixed. I'm reaching out on what I need to do. At this point and time, I really just want to send the watch back. God bless, love Walt.
