The Refurbished Garmin Forerunner 645 Music is a sports watch built for people who want not only reliable everyday activity tracking but also the convenience of music on the move. It sits neatly on the wrist and feels at home whether you are setting out for a daily run, heading to the gym, commuting to work or out for a long walk at the weekend. This is a watch that has earned its place in the routines of many runners, cyclists and active people because it combines solid performance features with a user experience that feels grounded in real use rather than flashy promises.
When you first pick up a refurbished unit you might notice traces of its previous life in the form of very light surface marks on the body or strap. These tell a story without affecting how the device performs and, over time, they fade into the background as you wear the watch more and more. What stands out instead is how comfortably the Forerunner 645 Music sits on the wrist. It is light enough to wear all day without irritation and the silicone strap is flexible yet secure, so it does not dig in during activity. On run after run you forget the watch is even there, which is precisely why comfort matters so much in everyday use.
The design of the Forerunner 645 Music balances functionality and simplicity. The display is bright and easy to read in various lighting conditions which matters significantly when you are outdoors and need to glance at pace, heart rate, distance or music controls. The interface is intuitive, with physical buttons that let you navigate menus and start or stop workouts without having to rely on touch controls alone. This is particularly useful when your hands are sweaty after a run or you are wearing gloves in cooler weather. The watch does not feel like something you need to master through trial and error. Instead it feels familiar quite quickly, whether you are an experienced runner or someone new to GPS watches.
The performance tracking of the Forerunner 645 Music is where the device shows its real strengths. Built in GPS acquires and holds a signal consistently across a range of outdoor environments. Whether you are navigating suburban streets, exploring wooded trails or pacing along coastal paths, the GPS provides reliable route tracking so you can look back on your runs with confidence. Heart rate monitoring from the wrist sensor offers a clear picture of effort during activity. While it might not match the precision of a chest strap for very specific training sessions, for most people it provides meaningful insight into how hard the body is working from easy runs to faster tempo efforts.
One of the defining features of this model is its music capability. With onboard storage for music and the ability to sync playlists from compatible services, you can head out for a run or walk without needing to take your phone with you. This becomes especially appealing on routines where you want freedom from carrying extra devices. You can pair your Bluetooth headphones to the watch, select your music and enjoy a seamless soundtrack to your activity. In practice this feature feels liberating because it removes a common friction point that many people face when trying to balance activity with entertainment on the go.
In everyday use the Forerunner 645 Music also handles notifications from your phone with subtle vibrations and clear text previews (where supported). This means you can stay aware of calls and messages without constantly reaching for your phone. It integrates into the rhythm of your day rather than distracting from it. Walking home from work or waiting for a bus, you can glance at your wrist and be gently informed of what you need to know, letting you stay present in the moment rather than buried in a phone screen.
Battery life on a refurbished Forerunner 645 Music remains practical for typical routines. When new it was designed to last through many hours of GPS tracking plus music playback without frequent charging. On a refurbished unit the maximum potential might be slightly reduced compared with new, yet in everyday use it still handles several runs and daily tracking between charges. Charging is simple with the included clip style cable that attaches to the back of the watch and plugs into a USB port. Many people find that charging every couple of days fits easily into their routine, whether they choose to plug in overnight or top up while getting ready in the morning.
Trace your week with this watch and you begin to see how it becomes part of both active and quieter moments. A morning run recorded with GPS and heart rate tracking feels satisfying when you review the data afterwards in the Garmin Connect app. Later in the day the watch continues to track steps and general movement, giving you a sense of how active you have been beyond formal workouts. Notifications from your phone arrive discreetly, and music playback puts your favourite tunes directly on your wrist. This combination of features makes the watch feel like a comprehensive everyday tool rather than a specialised device that only comes out for workouts.
Garmin Connect plays a key role in helping you make sense of all the information the watch gathers. After syncing with your phone, you can view maps, trend lines, split times and heart rate zones. The app becomes the hub for understanding how your training is progressing over weeks and months. If your goal is to improve pace on a regular route, the trend data can help you notice small improvements that might be hard to detect otherwise. If you are training for a longer event, the ability to view historical runs and compare sessions adds a layer of reflection that helps inform future training choices.
The Forerunner 645 Music also supports structured training plans that can be created or downloaded via Garmin Connect. These plans sync straight to the watch and prompt you through workouts with clear instructions. For people training for a specific distance or event, having that structure on the wrist is a helpful companion. It gives context to your efforts and encourages consistency without overwhelming you with unnecessary detail. Even casual runners appreciate having an organised framework that helps guide their sessions and keep them on track.
Durability matters in everyday life and the Forerunner 645 Music is built to withstand regular use. It handles sweat, rain and the knocks that come from an active lifestyle without complaint. Water resistance means you can wear it in wet conditions or during showers without concern. While it is not designed for deep diving, it stands up well to the rigours of running, walking and everyday wear. A refurbished unit may have minor cosmetic signs from previous use, but these do not affect how the watch functions or feels on your wrist.
Living with the Forerunner 645 Music over weeks and months reveals how it becomes more than just a piece of tech. It starts to feel like a personal record of your movement, effort and progress. You notice how your pace improves on familiar routes, how your heart rate responds to different intensities and how your overall activity levels vary through the week. These small insights add up and help you understand your training in a way that feels grounded and personal rather than abstract.
The combination of GPS tracking, heart rate monitoring, music playback and everyday notifications makes this model especially appealing for people who want a single device that handles many aspects of an active life. You do not have to juggle a separate music player or constantly check your phone for messages. Instead, the watch becomes a centre point that supports both your workouts and your daily life.
A refurbished Garmin Forerunner 645 Music often feels like a sensible and functional choice for people who value performance and convenience. The minor marks on a refurbished unit quickly fade from view as you use the watch and begin to appreciate its capabilities. It delivers clear data when you need it, sits comfortably on the wrist and integrates smoothly into your routines. Over time, the watch becomes familiar, reliable and easy to live with, giving you the confidence to focus on your training and daily activity without distraction.
This model is particularly well suited to anyone who enjoys having music on the move, wants dependable GPS and heart rate tracking, and values the simplicity of a device that supports their day rather than demanding attention. If you are considering other models with alternative features or capabilities you might explore watches with extended battery life or more advanced metrics to see how they compare with your priorities, but for many people the Forerunner 645 Music strikes a reassuring and practical balance that fits comfortably into everyday life.
