This must be an illness. As frustrated as I was with the software and a few other things with Garmin I could not resist the urge and replaced a F6 Pro Sapphire with the nylon red/black band with a F6 Pro Titanium. I remember reading someone else's description of the weight difference as a few grapes and not a big factor. Coming from and AW4/AW5 to the F6 Pro was like have a tumor sitting at the end of my wrist, but I really got hooked on the features and did adjust to the weight. Had problems with the sensors and one button stopped working so did a return and ordered the Titanium version. When I put it on I could not believe the difference that a few grams make. Really a nice watch, I hardly know that it is on. Also upgraded the software to 4 and have not had any issues. Earphones and sensors including HR good so far.
