Being a flagship in the Forerunner series by Garmin, the Forerunner 620 has proven that fitness technology can be wrapped in small package but without sacrificing functionality and sophisticated features such as built-in accelerometer, VO2 max estimation, virtual pacer, vertical oscillation, virtual partner, training effect, touchscreen, and recovery advisor.
Carrying all those things, Forerunner 620 delivers its purpose as a sport accessory with fitness computation. But now the flagship throne has been taken over by its younger sibling launched on October 21st, the Forerunner 630 which has everything available from the predecessor but with useful additions such as activity tracking and smartphone notifications.
Garmin Forerunner 620
Forerunner 620 is no longer the flagship in the series indeed, but its features still cover the needs for complete metrics measurement and analysis most runners want. The display is only 1-inch in diameter, producing 180 x 180 pixels resolution. The battery can last for up to 6 weeks in watch mode or 10 hours in sport mode.
Running features including cadence, ground contact time, and vertical oscillation in addition to VO2 max. When used for indoor run, there is an accelerometer to measure distance without requiring foot pod accessory.
The total number of steps taken with both left and right feet combined is called cadence, while vertical oscillation is the degree of bounce in running motion usually measured in centimeters. Ground contact time, as the name suggests, is the amount of time that your foot stays on the ground, and it is measured in milliseconds.
Those three features are available when you pair Forerunner 620 with HRM-Run which is available as a bundled accessory or can be purchased separately. There is a separate accelerometer in the HRM-Run to analyze torso movement and compute the metrics to provide the aforementioned data.
Apart from the traditional features such as Auto Lap, Auto Pause, Auto Scroll for data pages, advanced workouts planning, interval training, personal records, and distance/time alerts, Forerunner 620 also estimates VO2 max or the body’s maximum possible consumption of oxygen.
When paired with heart rate monitor, many variables including speed, heart beat per minute (BPM), and variability of heart rate are analyzed to determine the VO2 max. Based on that estimation, the watch will measure physical fitness and predict recovery time you need.
Based on physical fitness and heart rate, Forerunner 620 suggests recovery time or the amount of time you need for resting before having another intense workout. There is also recovery check that kicks in to assess recovery level after the first 6 minutes of running.
Recovery suggestions are represented by color-coded gauge: red means more than 3 days of recovery, while green indicates that you are good to go.
Advanced workout features to create custom goal-based training plan is available from Garmin Connect website. A variety of targets are allowed including cadence, speed, heart rate, and pace; you can also set the duration or time and distance. Once the plans are created, you can download it to your Forerunner 620 via either USB cable or Bluetooth connection.
Garmin Forerunner 630
This is the watch that currently sits on the top of the Forerunner series. Intended to be a better running watch than the previous flagship, Forerunner 630 brings all the features that you can find on the Forerunner 620.
Both hardware and software have been refined that the Forerunner 630 has wider screen at 1.23-inch producing 215 x 180 pixels resolution. The battery can last for 16 hours in training mode or 4 weeks in watch mode with smartphone notifications on. And Garmin Forerunner 630 is built to work with GPS and GLONASS satellites.
It can display text, email, and other alerts when paired with a compatible smartphone. Similar to the predecessor, Forerunner 630 measures a lot of variables necessary to make suggestion about recovery time.
The computations will include VO2 max and running dynamics such as cadence, vertical oscillation, and ground contact time. There are also additional running dynamics available only on Forerunner 630: stride length, vertical ration, and ground contact time balance.
Besides functioning as running watch, the built-in accelerometer measures the number of steps you take, movements you make, and monitors your sleep. If you are static for too long, the watch will remind you to engage in physical activity by giving alerts.
Another good feature is that Forerunner 630 is compatible with Connect IQ, an app store owned by Garmin. There are currently more than 1,000 apps in the store to customize Forerunner 630 in terms of data fields, watch face, functionality, and widgets.
