Overview of the Forerunner 645 Music: top of the range with more music!
Designed essentially to run in music without a Smartphone and pay for small purchases without taking out your bank card, this high-end Garmin running watch offers the advantages of the Forerunner 735XT or even the Forerunner 935 without the triathlon functions but with the added bonus of access to a mp3 player on-board (Garmin will soon offer access to the Deezer platform), 4 GB of memory and an NFC chip for the contactless payment (Garmin Pay system). In addition to these 2 main innovations, this model is the first in the Forerunner series to have a steel bezel and a high resolution Garmin Chroma Display non-touch which, moreover, remains permanently on.
Listening to music while running can help with concentration, improving performance and physical ability. The music, by diverting the attention of the sportsman, can even make forget the tiredness and the pain.
We find a GPS chip, GLONASS and, new for 2025, Galileo, an optical sensor on the wrist, sensors worthy of adventurer watches (compass, thermometer, gyroscope), advanced navigation functions (point-to-point navigation, breadcrumb trail , return to start, TracBack, altitude profile, vertical speed, etc.), advanced training and tracking functionalities (training tracking and status, stride and cadence analysis, race dynamics analysis, predictor , VO2max, and much more) found on high-end models (Forerunner 735XT, 935, 945), an activity tracking function and smart health connected watch functions (SMS notifications, calls and emails but also, new, the possibility of sending SMS, e-mails and messages on social networks!).
Pay for your purchases with ease with Garmin Pay contactless payment!
Also new on this high-end watch: after its introduction to the Garmin Vivoactive 3 sports smart health connected watch, the contactless payment allows you to pay for small purchases with your watch as with a contactless bank card or a Smartphone. This innovation is also found in the Apple Watch Serie 3. This system uses NFC (Near Field Communication) radio wave technology that the Android Wear OS now knows how to pilot and which equips most bank cards and smartphones.
In practice, the user must create an account in order to associate his bank card with an identifier then update his watch. Payment is made by activating the function with a secret code and by approaching the watch from the card reader. The function remains active for 24 hours and deactivates if the watch is removed from the wrist or if the optical sensor is deactivated.
GarminPay will soon be available in France and usable by customers of partner banks at merchants accepting this payment method.
Compared to other Forerunner models, this mp3 watch is more open to indoor and outdoor leisure activities with 15 sports available including yoga, bodybuilding, skiing, stepper, rowing, stand-up paddle, and of course running, treadmill, swimming (no open water function, however), indoor or outdoor cycling (spinning, health home trainer). Thanks to its numerous sensors, you have relevant data and measurements such as elevation, climb speed, altitude profile and much more. The watch can count the number of lengths in the pool or the number of repetitions in bodybuilding. It also offers the classic GPS navigation functions: track recording, breadcrumb trail, return to departure point, TracBack, point-to-point navigation, distance to destination.
The watch is not a "real" multisport in the sense that there is no automatic or manual transition between activities as is the case on the Forerunner 935 or the latest (May 2024) Forerunner 945 So you will have to stop recording midway to change activity. For triathlon, it is better to turn to the Forerunner 735XT, the Forerunner 935 or the very complete Forerunner 945 which offers color mapping. See also our file: Best triathlon watches 2023.
An advanced analysis of your performance to help you progress
Garmin has integrated into the Forerunner 645 most of the advanced analysis functions useful for athletes to improve their technique and monitoring their progress. We find most of the analysis functions available on the Forerunner 935: running dynamics (Running Dynamics) for stride analysis (balance at ground contact time, stride length, cadence, vertical oscillation), VO2max estimate, race time estimate (race predictor), training status and tracking, aerobic / anaerobic distribution, fitness and age estimate, and other data useful for your training ( Note that the measurement of running dynamics requires a Running Dynamics Pod or an HRM-Tri or HRM-Run heart rate belt, sold separately). The watch assesses the quality of training, recovery time and performance. In short, a rather complete tool to help you progress. Learn more on the Garmin site.
To have all the biometric data, you will need to acquire an optional accessory, the Running Dynamics Pod, or a chest belt HRM-Run which already includes this sensor.
Thanks to its 15 integrated profiles, the watch can cross trainings and accumulate statistics.
