Since the Garmin announced the Forerunner 55 which is a new, entry-level, simple to use and dedicated running watch, we would like to compare Garmin Forerunner 45 vs 55 side by side.
Key Differences between Forerunner 45 and 55
Here is the complete list for the key differences between Garmin Forerunner 45 and 55:
The Forerunner 55 is kind of an updated or next step up from the very popular Garmin Forerunner 45 which has been around since 2019. There are three features that stand out for us with the new Garmin Forerunner 55 compared to the Garmin Forerunner 45.
The first, what we expect from a running watch to estimate the finish time during the race. So, you wouldn’t have to keep recalculation your pace. We are so excited to see that this new feature is now built into the Forerunner 55. On the other hand, the Garmin Forerunner 45 and 45S do not have it.
The second most noticeable upgrade on the Garmin Forerunner 55 is the improved battery life which is pretty much doubles that of the Garmin Forerunner 45. The Forerunner 55 has two weeks of battery life in smartwatch mode and up to 20 hours in GPS mode.
Also, we loved the addition of track run mode a dedicated built-in application for accurate workout data when doing those important track sessions as part of your marathon training.
There are many more additional features built into the Garmin Forerunner 55 compared to the Garmin Forerunner 45. The ones we mentioned are the ones that we found most interesting. Also, we found these reasons enough to consider buying the Forerunner 55 over the Forerunner 45.
The core features of both are the same, such as always on display that’s clear and easy to read in bright sunlight. When you are at your most tired during those runs with sweat in your eyes and for nighttime training there is also an excellent backlight and no fiddly touchscreen with just five intuitive easy to use push buttons.
You also get the same 5 ATM water resistance which means you don’t have to worry about jumping into the sea or pool with both Forerunner 45 and 55. After that long hot run, it won’t track any of your data from your swim.
Garmin offers smart watches with open water swimming profiles including our Garmin Instinct Solar with 100 meters water resistance. But, a swimming profile mode of Forerunner 55 is another thing to consider the Garmin Forerunner 55 instead of Forerunner 45.
One more key difference between the Forerunner 45 and the 55 is the case size options. The Garmin Forerunner 55 is only available as 42 millimeter. The Forerunner 45 has also 42 millimeter option. But, you have the option of the 45S which has the same display size but in a smaller case size of 39 millimeters and with a shorter strap length. This could be a much better choice for runners with smaller wrists when comparing the 45 and the 55.
So, if you’re looking for a small size, light and comfortable fully capable running watch at the lowest possible price, then the Forerunner 45S is still a fantastic GPS running watch with built-in heart rate monitor on the wrist and with a fantastic battery life for just 149 dollars or less.
