After the Bluetooth connection to my iPhone dropped, the watch won't reconnect. This scenario will happen to most people on a regular basis. To reconnect you will need to power cycle your watch and/or sometimes go through the pairing process again. I literally do this 3+ times a day. Garmin sent me a replacement and the same thing is happening with the new watch. This appears to be a known issue with the iPhone that Garmin has been unable to resolve. If you have an iPhone, don't buy this watch. This problem renders an otherwise good watch useless.
