Runners are likely to continue to favor strap-on chest sensors to measure their heart rates, according to Reiner, who indicated that such sensors are supported by Garmin's devices but do not appear to be compatible with the Apple Watch. Furthermore Apple Watch costs $350, versus $130 to $170 for Garmin's products, and the Apple Watch's battery life is much shorter, according to Reiner, who added that Garmin is "heaving a slight sigh of relief." Citigroup analyst Jeremy David, meanwhile, wrote that the Apple Watch does not compete with Garmin's trackers. Apple Watch must be paired with iPhones to accurately measure distance, while its price is high, David stated. Additionally, the device's battery life appears to be well below that offered by Garmin's devices, according to the analyst, who kept a $70 price target and Buy rating on Garmin.
