Garmin Forerunner 255 Vs Forerunner 245: What’s Different?

Garmin’s Forerunner 255, an update to the Forerunner 245, was released in 2018. These watches are great for running and exercise and they cost significantly less than high-end Garmins like the Fenix7.

They lack touchscreens and don’t offer top-tier Garmin features such as full bike turbo trainer control or on-watch maps. The Garmin Forerunner255 has seen some significant improvements over the years, which makes it more comfortable as a current-generation model.

These are the main differences in the Forerunner 255.

Garmin Pay and NFC

Garmin Pay was not available on the Forerunner 245 because it did not support NFC. The Forerunner255 fills the gap to make the watch more intuitive, even though it is not essential for a running/fitness watch.

Two sizes are available now

The Forerunner 245 is available in one size. It measures just over 42mm in diameter. It’s not big, but it’s not small — a design that is well-suited for a wide range of users.

Garmin has a 255 series. There are two sizes. There are two sizes. The Forerunner 255 standard has a face that is 46mm wider than its predecessor. While the Forerunner 255S has a face that is 41mm smaller. It is cute and small.

This split can be seen on other Garmin models and provides non-top-end buyers with a variety of designs.

New heart rate sensor

This was easy to predict: The Forerunner 255 shares the Elevate V4 heart-rate sensor technology with the Garmin watches. For greater accuracy, it has more light sensors that the Forerunner 245.

The array is used by most Garmin watches, including the Venu 2 (and Fenix 7). The results are generally excellent, and the Forerunner255 will be no different. The Forerunner 255, which is a lighter watch, may have a slightly better stability than other top models. This means that the watch is less likely to bounce around.

Status of HRV

Garmin uses its most recent heart rate tech in order to deliver HRV status, a new feature that was introduced in the Forerunner 955 and 255. This measures your heart rate variability over the night and gives you a score every day.

HRV measures the time variation between your heart beats. It is measured in milliseconds. A higher level of variability is a sign that you are more fit, have lower stress levels, and are better rested. To see HRV results, Garmin used a chest strap in the past. The Fenix 7 and other recent watches let you extract HRV data from Health Snapshot mode. However, HRV Status makes it easier to access the data since it’s an overnight passive reading.

Health Snapshot requires you to remain still for at least two minutes. This makes it something that you won’t use very often.

GPS multi-band

Garmin has almost completely upgraded its watches’ heart rate readers, and now it can do the same with GPS. Multi-band GPS allows the Forerunner 255 to connect to multiple satellite networks simultaneously, allowing it to track more accurately where it is.

It isn’t something you would use every day. Multi-GPS requires more battery for active tracking. This is why it’s useful in areas with poor signal. It’s a good idea.

Accessories that require more support

Garmin’s Running Dynamic pod or HRM-Pro chest strap can be used with the Forerunner 245 already. The Forerunner 255 is more compatible with them, showing you the power metrics they calculate as you work out.

Although this isn’t a major deal for most people it does make Forerunner 255 appealing to the more hardcore crowd.

First Impressions

This low-mid series is not strayed far from the Forerunner 255. There are no on-watch maps and no solar option. This is also not the case with Instinct Solar.

Garmin Forerunner 245 owners don’t necessarily have to upgrade to Forerunner 255. It was necessary to make the Forerunner series 2xx more relevant than the Venu and Instinct watches, which are both available at the same price.
