The Garmin Brand

Garmin has been in business, creating technology since 1989, bringing their specialized GPS navigation systems to the United States and eventually to Europe and Asia. Initially, as a brand, Garmin aimed to deliver its GPS navigation and technology across several industries, not only fitness. These industries include marine, automotive, aviation, sports, and the outdoors as well. 


More recently, Garmin began to compete with other smartwatches in the market. However, unlike other smartwatches, Garmin’s Forerunner line (and many of their other watches) is focused on training for marathons, swimming, and cycling. They aim to be innovative, and a creator of the best products on the market; Garmin works hard to bring their navigation and technology to the outdoors.

Side by side comparison 245 vs 735


GPS and map features for the Garmin Forerunner 245 vs. the 735  specs don’t seem all that different at first glance. Both watches offer a built-in GPS and a GPS mode setting and are both equipped with features such as GPS time sync, sensors, and speed and distance. Both also have GPS coordinates and GPS-based time, pace, and distance.


The 245 boasts its built-in GPS as one of its most important selling points, encouraging runners to let the watch do all the work for you. The GPS can track and calculate your stats to help you improve your form, goals, and overall training. 


The 735 model also takes pride in its GPS technology and focuses on providing you with even more in-depth stats about your progress. However, it seems to focus on “doing it all” rather than the GPS features alone.


The Winner – A draw

Run Tracking Features 245 vs 735

Apps and Device Compatibility

The Forerunner 245 includes the Garmin Coach feature. This feature allows you to try out different training plans for 5K, 10K, or marathons. While training, you receive advice from expert running coaches and plans that sync to your watch for free. You can also make sure to keep safe with the 245 thanks to its incident detection and assistance abilities.


The Forerunner 245 is compatible with iPhone, Android, Bluetooth, and Ant. However, certain features are only compatible with one or the other when it comes to smartphones. For example, if you’d like to share your running journey, the Life Event Sharing option is only compatible with android. 


Certain other running features require a compatible accessory as well. You can still make activity profiles for other sports or workouts for swimming, rowing, cycling, and workout equipment like elliptical machines and stair masters.


So how does the Garmin 735 vs. the Forerunner 245 compare?


The 735, according to Garmin themselves, is the “ultimate smartwatch for athletes.” It earned this name thanks to its ability to send you notifications from your phone directly to your watch while you are training. Garmin Connect is also available on this watch, meaning you can share your progress and receive encouragement from friends and family. The 735 is also an easily personalized watch with free watch face designs, apps, and data.


While the 245 is excellent for training, it seems that the 735 is more tailored to suit your specific progress and aesthetic. The smart notifications also mean you don’t need to check your phone while you’re training, allowing you to check your notifications more easily but opt out of answering them when you don’t want to pause your routine.

Training Aids

Both of these watches have a slew of helpful tech and features to help you train. 

The Forerunner 245 has the following training aids available:


Running dynamics, VO2 Max, Pulse OX Sensor. You can access Running dynamics with a compatible accessory. It allows you to measure running metrics. At the same time, VO2 Max is a metric to help you understand changes in your performance caused by outside factors. The Pulse OX Sensor estimates your blood oxygen level through your wrist.


The 245 also has Training Status, Training Effect, and Training Load. The first helps you evaluate your history and see if you’re progressing in the right direction. Training Effect keeps track of your development with things like speed and endurance and offers feedback. Lastly, The Training Lode logs the last week’s worth of your training and compares it to the rest of your recent training history.


So how does the Forerunner 735 compare to the Forerunner 245 when helping you train?


Like the 245, it also has Running Dynamics (but you need a compatible device to use it), VO2 max estimates, and a way of receiving feedback. (These seem to be critical features in Forerunner series watches.) 


However, as the slightly more upscale version, the 735 has additional helpful metrics to help you progress.


For example, you can change your exercise or training routine with built-in activity profiles for running, swimming, biking, and even triathlons. You can even keep track of your underwater heart rate. You can also receive live feedback as the 735, according to Garmin, is the first training watch to be compatible with Strava Live Segments. You can also view ranking, receive alerts for segments, and see how you compare!


This watch claims to do it all, and it certainly seems to be true.  In addition to its customizable look, training features, and apps, it even offers a multisport feature that allows you to change your sport just by pressing a button.
