Part Number 010-02120-A4
The exclusive watch face for the Forerunner 245 Music Japan Edition takes sacred Mount Fuji as its theme, perfectly complementing the design of the watch casing.
Forerunner 245 Music Japan Edition gives the born-to-run Forerunner 245 Music a bold red and white facelift. Its new look will inspire you to reach new heights and set new personal bests. Forerunner 245 Music Japan Edition features a matching red and white strap that not only catches the eye but also nods to the highest competitive ambitions of runners everywhere. Its metal buttons and buckle are complemented by a edition serial number plate, driving athletes’ desire to be among the medal winners. The exclusive Connect IQ watch face combines Mount Fuji with the sun disc of the Japanese flag, representing each runner’s determination to scale new peaks of performance.
If you can’t run without the perfect playlist, you won’t be able to run without Forerunner 245 Music. Sync your carefully crafted playlists from select music streaming services¹ — such as Deezer and Spotify — to your watch for ad-free listening. You can even store up to 500 songs right on your watch. It’s easy to transfer music from your computer and then queue up your favorite playlist for easy listening through headphones enabled with BLUETOOTH®technology.
What amount of training is right for you? Forerunner 245 Music offers personalized training and recovery insight for smarter training decisions, helping you prepare for your next race. It keeps tabs on your VO2 max and understands how heat and altitude impact your performance. And the higher your VO2 max, the higher you can expect to perform, which is exactly what is shown by the performance condition metric. Training status evaluates your recent exercise history and performance indicators to let you know if you’re training productively, peaking or overreaching. See how your workouts influence the development of endurance, speed and power with aerobic and anaerobic training effect feedback. Recovery time helps you maximize the benefit of your efforts by predicting when you will be ready for your next tough challenge. You can even view your overall training load, which measures your exercise volume from the last 7 days and compares it to the optimal range for your fitness and recent training history.
Running is what you do, so train smarter with the tools available from our Garmin Connect online fitness community. Create your own custom workouts, or download free ones that sync right to your watch. Or, if you’ve got a specific goal in mind for your next 5K, check out Garmin Coach. Featuring guidance from expert coaches and free training plans that adapt to you and your goals, it’s a foolproof way to get to the finish line. As part of your training plan, it can even help you predict your race time. What about when you want to switch it up? Forerunner 245 Music also has activity profiles for cycling, pool swimming, indoor rowing and even for using the elliptical or stair-stepper.
The Forerunner 245 Music GPS smartwatch also has the tools you need to improve your running form. The watch measures crucial running metrics² such as cadence, stride length, ground contact time and balance, vertical oscillationand vertical ratio. These measurements are the key to understanding your form, so you can bring your best on every run and at every race. Your Forerunner 245 Music can start tracking these metrics with the addition of a compatible heart rate strap or the compact Running Dynamics Pod, which clips right onto your waistband.
Check out our Connect IQ store, where you can add personality to Forerunner 245 Music by downloading apps, widgets, watch faces and more. It’s easy and — even better — it’s free. New apps are added every day, so you can keep tabs on when your Uber will arrive, turn on your lights at home with the SmartThings app, and even use the AccuWeather MinuteCast app to find out when the rain will start.
Forerunner 245 Music makes it easy to run without leaving important smart features behind. Once paired with your compatible smartphone, you’ll be able to receive text messages and see social media updates, emails and more right on your wrist. And new safety and tracking features make it easy to share your location with chosen contacts in case you need assistance — manually, or automatically with built-in incident detection, if needed. So, lace up your shoes, and head out with a little extra peace of mind.
Syncing your activities to Garmin Connect is for more than just storing your data. Garmin Connect is a thriving online community where people on the go can connect and compete by joining challenges, encourage each other’s successes and even share their triumphs via social media. Garmin Connect is free and available on the web or on your smartphone.
The Forerunner 245 Music smartwatch has tools to help keep tabs on your overall well-being and the sleep4 you’re getting at night. These tools provide crucial insight you can use to maximize your training. For example, it’s our first running watch to include a Pulse Ox sensor5. This wrist-based sensor estimates your body’s blood oxygen saturation, which can help gauge how your body is absorbing oxygen — especially while you sleep. And to give you an idea of how you’re sleeping, Forerunner 245 Music tracks your light, deep and REM stages of sleep, along with movement throughout the night. It also features all-day stress monitoring for wellness tracking during the day. If your stress level starts to climb, use the relaxation breathing timer for a few minutes of guided breathing, which can help calm your mind and body. And to help you optimize your body’s energy, Body Battery energy monitoring uses collected data to gauge your energy reserves at any moment, so you can plan your day to optimize times for activity and rest.
