Garmin Forerunner comparison: choosing the right sports watch

Garmin’s Forerunner series has lately expanded with a number of new GPS watches. The 45/45S, 245/245 Music, and 945 are all included. There are still six gadgets in the overall line, but they are now more modern in appearance and have some added smarts. Here’s how they stack up against each other.

With so many sports watches to choose from, you may be unsure which one is best for you. Hopefully, the information in this guide will be useful.

Garmin Forerunner vs. Garmin Forerunner

Garmin Forerunner 35 Pros and Cons of Choosing the Right Garmin Forerunner Watch Affordably priced, with built-in GPS and a long battery life

Cons: No altimeter, black-and-white screen, and a lack of sophisticated performance metrics

This Forerunner watch is designed for folks on a tight budget. Garmin’s Elevate wrist heart rate technology is included. This device will assist you in heart-rate zone training and, like most Garmin devices, will monitor your vital resting heart rate.

There’s also a built-in GPS for phone-free training, however GLONASS/GALILEO isn’t supported. The addition of built-in GPS raises the price, but it is a great purchase.

Garmin has also included a few advanced performance metrics. This covers fitness age and VO2 max.

The timepiece doubles as a 24/7 activity tracker, counting steps, calories, and distance throughout the day and sleep at night, thanks to an accelerometer. When you’ve been sitting for too long, the move bar with vibration warnings encourages you to get up.

You’ll also discover smartwatch features like smart notifications and audio prompts, as well as customization options and exceptional battery life, as with other Garmin Forerunner watches.

Pros: Affordable, full-color screen, Body Battery function, Forerunner 45/45S Guide to Choosing the Right Garmin Forerunner Watch

Cons: There’s no altimeter, and there aren’t many advanced performance metrics.

Another choice for those seeking a low-cost way to get into the world of running watches is this one. The Forerunner 35 is effectively replaced by this gadget. Garmin, for some reason, continues to sell both. A tiny 45S (39.5 x 39.5 x 11.4 mm) and a large 45 (42 x 42 x 11.4 mm) variant are available.

Unlike its predecessor’s B&W screen, the 45/45S’s display is full color. Garmin has also switched from a rectangular to a circular display. There are other minor enhancements, including support for GLONASS/GALILEO.

Garmin’s new Body Battery feature is also included in the watch. This uses data from your heart rate variability (HRV), sleep, and activity to determine your body’s energy levels.

Incident detection is an intriguing addition. If the watch detects an accident, the app will send an automated text message and email to your emergency contacts with your name and GPS location. This is done by the watch using your associated compatible smartphone.

Instead of the Forerunner 35, we recommend this one if you’re looking for a budget running watch. It’s only about $30 more, but the extra features are well worth it.

Garmin Forerunner 245/245 Music Guide to Choosing the Right WatchPros: Designed for more serious runners, including a variety of advanced performance indicators, a pulse oximeter, and the ability to store music.

Cons: There is no altimeter.

This is a more feature-rich watch that takes the place of the wildly successful Forerunner 235.

The 245 comes with several sophisticated performance measures in addition to everything the lower-spec devices provide. Recovery Time, Race Predictor, Performance Condition, Anaerobic/Aerobic Training Effect, Training Load, Training Status, and other factors are all included. Needless to say, having this kind of data elevates workout analysis to a whole new level.

A compass and a PulseOx sensor are the other additions. The 35, 45, and 245 don’t have a barometric altimeter for counting floors, which is unusual. Because it monitors your blood oxygen level, a PulseOx sensor is a worthwhile addition. For more advanced sleep statistics, this is mostly done at night, though manual readings can be collected at any time.

Overall, for the price, this is a well-rounded watch that will easily suit the demands of most runners. You may also get the 245 Music, which is the same gadget but with 500 songs of local storage.

Choosing the Right Garmin Forerunner Watch (Forerunner 645/645 Music)

Advantages: Music storage, NFC for Garmin Pay

Cons: There is no pulse oximeter, and there is no body battery feature.

This is the first Garmin device to include built-in music storage, and it’s been around for more than a year. There are two versions to choose from: one with music and one without.

A barometer altimeter, gyroscope, and thermometer are included in the watch. These aren’t available in the Forerunner versions described before. However, it lacks the 245’s PulseOx Sensor.

Other differences to be aware of include a few extra performance stats, as given in the table below. Because the Body Battery and Incident Detection functionalities were released after the watch was released, they are not included.

It does, however, feature a Garmin Pay NFC chip. You can now reward yourself with a well-deserved snack on your way home after your run — no cash or credit card required.

735XT Forerunner

Pros and Cons of Buying a Garmin Forerunner Watch Its cost is decreasing, and it now offers multi-sport support.

Cons: It’s about three years old, and it’s missing some sensors and sophisticated performance metrics.

The 735XT is the oldest gadget on this list, having been released in mid-2016. However, it’s still a fantastic watch, demonstrating the high quality of Garmin’s products.

The 735 XT is really less expensive than the 645 and comparable to the 245. Because it is likely to be phased out shortly, it may be drastically discounted in the future.

Nonetheless, we recommend purchasing one of the newest devices. The barometric altimeter, gyroscope, thermometer, and PulseOx sensor are all missing from the 735XT, as are several sophisticated performance metrics and newer capabilities like Body Battery and Incident detection.

It does, however, have multi-sport support as well as other sports profiles such as open water swimming and enhanced cycling capabilities.

945 Forerunner

The Pros and Cons of Buying a Garmin Forerunner Watch Pros: Built for fitness enthusiasts, this device includes everything Garmin has to offer, including multi-sport support and full-color on-board maps.

Price is a disadvantage.

The Forerunner 945 is the granddaddy of the group. It does pretty much what the others on this list do, plus it adds some more complex performance stats and sports support. This covers golf and other outdoor activities (Hiking, Climbing, Skiing, Snowboarding, XC Skiing, Stand Up Paddleboarding, Rowing, Kayaking). The music memory has also been increased, allowing for the storage of up to 1,000 songs.

The watch has advanced physiological functions and is designed for serious athletes. Heat and altitude acclimatization status have been adjusted in the training status. There’s a focus on training load, which categorizes your training load, recuperation time, and more specific aerobic and anaerobic training impacts.

Another significant enhancement is full-color onboard maps that will keep you on track so you don’t get lost. This is identical to the Fenix line’s most recent release.

If you want the greatest running/triathlon watch on the market today, go for the Forerunner 945. Because it is a little pricey, another choice is to go for the 935, which is its predecessor.
