If you're looking for an Apple Watch that low is cost and does what you need I highly suggest the Series 3. While I have one I also bought one for my boyfriend and let me tell you it helps so much throughout the day. We only needed something that can track health, stocks, and show us our notification whiteout always going on our phones 24/7. this watch does so much for for a decent price.
Thanks for the recommendation Kenna, I am looking to add another apple product to my collection and want something that functional, tracks health and can alert me to messages and phone calls that I normally miss because my phone is in a pouch or pocket.
