Look elsewhere if…
There are several things that you cannot find on both the Garmin Forerunner 235 and 735XT.

You will need to have your phone around so that you can run or exercise to your favorite tunes.
If you are looking for a running watch that has a SIM slot so that you can use your device as a standalone phone, rather than connecting it to your smartphone, then you are out of luck with the Forerunner 735XT and 235. Speaking of your smartphone, there are not too many connected features to expect from both of these devices. You cannot use either the 235 or the 735XT to reply to incoming text messages or answer a call.
Also, even with the GPS antennas onboard, none of these devices will give you visual maps like the ones you see on your cars.
Final recommendations: Should you buy a Garmin Forerunner 235? Or spend more for a Garmin Forerunner 735XT?
The Garmin Forerunner 235 is one of the very first devices under this line of running focused smartwatches. At its price, it includes a heart rate monitor and GPS, sensors that you normally find on more expensive watches. The Garmin Forerunner 235 is not just a glorified pedometer; it can help you improve, be more fit, and healthier. It is an excellent tool if you are training for a marathon or just starting out.
Beginners will appreciate just how easy it is to use, and how it limits the data to only the essentials. However, if you like the 235, you might like the Garmin Forerunner 735XT a whole lot more.
The Garmin Forerunner 735XT adds a compass to the list of sensors you find on the 235, while also slightly trimming the size and weight of the 235. It has more features as well, such as the sunset and sunrise times, the ability to use your phone to find your watch, and getting percentages for your current heart rate compared to your maximum and resting HR.
However, it does cost more, and if you look at it closely, you would realize that not much has been added that would really make the Garmin Forerunner 735XT stand out and leave the Forerunner 235 in the dust. However, for those who are training for a triathlon, or has swimming and watersports in your list of exercises, then you might as well add an additional $100 and get the 735XT.
