I have a Suunto Core Alu that has been through loads of abuse in the last 6 years and is still working great. However I wanted a heart rate option. I decided to go to a Garmin Instinct for my new ABC watch. It is fantastic! They can be bought for only $199. Using GPS, the altimeter function is more accurate that using baro alone. There are some great reviews online for the Instinct. I would highly recommend it. The sunrise/sunset widget is great for determining viewing times for wildlife.
