Garmin Forerunner 45 Watch Review

The One Thing I Didn’t Expect from the Garmin Forerunner 45 Watch

When the desire to push my endurance limits, particularly in running and rucking, intensified, I found myself in need of a reliable training companion. My current fitness tracker was simply not cutting it, lacking the precision and focused metrics I required. This led me to the Garmin Forerunner 45 Watch. Initially, I was drawn to its reputation for robust GPS tracking and the promise of detailed performance data, expecting it to be a solid, if standard, addition to my gear. The sleek, lightweight design and the black, fiber-reinforced polymer case felt sturdy yet unobtrusive, a good first impression for something intended for constant wear. I’d briefly considered a few other fitness watches, but their feature sets felt either too bloated with features I wouldn’t use or too rudimentary. My first impression upon unboxing was one of practical efficiency; it felt ready to go.

Real-World Testing: Putting Garmin Forerunner 45 Watch to the Test

My testing primarily revolved around my regular training regimen, which includes early morning runs on local trails, longer weekend road runs, and consistent rucking sessions with a weighted pack on varied terrain. These activities were conducted in a range of conditions, from dry, dusty paths to light rain, and across temperatures that fluctuate significantly throughout the day. The watch’s sunlight-visible, transflective memory-in-pixel (MIP) display proved exceptionally easy to read even under harsh midday sun, a critical factor for quick glances during strenuous activity.

The initial setup was straightforward. Pairing the watch with my smartphone via the Garmin Connect app was seamless, and navigating the basic functions felt intuitive. The button-driven interface, while not touch-screen, was responsive and allowed for easy operation even with slightly sweaty hands. I did encounter one minor quirk early on: the alarm for my morning run seemed to be a bit too subtle initially, but adjusting the vibration intensity within the settings resolved this without issue.

After several weeks of continuous use, the Garmin Forerunner 45 Watch has become an indispensable part of my training. Its rechargeable Lithium-Ion battery consistently delivered close to the advertised up to 7 days of battery life in smartwatch mode, and the 13 hours of GPS mode battery life was more than sufficient for even my longest endurance efforts. I experienced no discernible drop in performance or accuracy over time. Cleaning the watch is as simple as a quick wipe-down with a damp cloth, and the silicone band shows no signs of degradation or discomfort from constant wear, even during prolonged, sweaty sessions. Compared to my previous fitness tracker, the GPS accuracy and heart rate monitoring on this Garmin unit are leaps and bounds ahead, providing much more actionable data for my training goals.

Extended Use & Reliability

The Garmin Forerunner 45 Watch has proven its mettle through consistent daily use. Its water resistant mark of 5 atm meant I didn’t have to worry about it during those unexpected downpours on my runs or even during basic water-related chores around the house. The watch face, made of glass, has resisted minor scuffs and scrapes from accidental bumps against door frames and equipment. I’ve found its reliability to be a significant factor in my improved training efficiency; I can trust the data it provides.

Maintenance is minimal. A quick rinse and wipe after particularly dusty or sweaty workouts keeps it looking and functioning like new. The charging cable, a standard Garmin proprietary connector, attaches securely and charges the device relatively quickly. Unlike some more complex wearables that require frequent software updates or intricate care, this model remains unfussy. Its performance has remained consistent, a stark contrast to previous devices where battery life would noticeably degrade after a few months.

Breaking Down the Features of Garmin Forerunner 45 Watch

Specifications

The Garmin Forerunner 45 Watch presents a compelling package of specifications designed for dedicated runners. Its case boasts a diameter of 42 mm, making it a noticeable yet comfortable presence on the wrist, while the case diameter of 26.3 mm refers to the actual display area. The bezel, finished in fiber-reinforced polymer, contributes to its lightweight yet durable feel, tipping the scales at a mere 36 g.

The lens material is glass, offering decent scratch resistance for everyday wear and training. The display itself is a digital, sunlight-visible, transflective memory-in-pixel (MIP) type with a resolution of 208×208 pixels. This combination ensures excellent readability in all lighting conditions, from bright sunlight to dim indoor environments, without significant battery drain.

For power, it utilizes a rechargeable Lithium-Ion Battery, offering up to 7 days in smartwatch mode and a solid 13 hours in GPS mode. This longevity is a critical advantage for multi-day events or when you simply forget to charge it for a night. Its water resistant mark of 5 atm means it can handle splashes, rain, and even swimming, though I’ve primarily used it for running and rucking.

The band, presented here in Lava Red silicone, is comfortable and flexible for all-day wear, conforming well to the wrist. The watch is categorized as unisex and is specifically tailored for the running application, though its versatility extends beyond that. Included accessories are the essential charging cable and documentation, which are standard for most Garmin products.

Performance & Functionality

The primary function of the Garmin Forerunner 45 Watch is its performance as a GPS running watch, and in this regard, it truly shines. The GPS tracking is consistently accurate, providing reliable pace, distance, and route mapping, even in areas with dense tree cover or urban canyons. My personal testing confirms that the heart rate monitor is highly accurate, significantly improving my training efficiency by allowing me to stay within specific heart rate zones. This accuracy has been invaluable for dialing in my endurance efforts, ensuring I’m training optimally and not over-exerting or under-training.

The strength of this watch lies in its focused approach. It delivers all the essential running metrics without the clutter of overly complex smartwatch features found in higher-end models. The data it collects is readily accessible through the Garmin Connect app, presenting clear graphs and summaries of my workouts. The only minor limitation I’ve found is that its activity profiles, while robust for running, are less extensive than some of Garmin’s more premium sports watches. However, for its intended purpose, its functionality is superb.

Design & Ergonomics

The Garmin Forerunner 45 Watch strikes an excellent balance between functionality and wearability. Its 42 mm size is a sweet spot – large enough to present information clearly but not so bulky as to be cumbersome during an intense workout. The fiber-reinforced polymer bezel and silicone band contribute to its lightweight feel, making it comfortable for continuous wear, both during exercise and sleep.

The button-controlled interface is a deliberate design choice that pays dividends during sweaty or wet conditions. Each button has a distinct feel and placement, allowing for easy tactile navigation without needing to look at the watch. This is particularly beneficial when you’re focused on your stride or navigating a challenging trail. The Lava Red band, while perhaps a bit vibrant for some, adds a touch of personality and visibility. The overall build quality feels solid and durable, ready to withstand the rigors of regular training.

Durability & Maintenance

In terms of durability, the Garmin Forerunner 45 Watch has held up remarkably well. The glass lens has resisted the minor abrasions that come with regular training. I’ve yet to experience any issues with the silicone band becoming stiff or brittle, even with constant exposure to sweat and the elements. The 5 atm water resistance rating provides peace of mind, as I’ve encountered light rain and splashes without any adverse effects on its operation.

Maintenance is refreshingly simple. A quick rinse with water and a gentle wipe with a soft cloth after each use keeps the watch clean and functioning optimally. The charging port is robust and has maintained a secure connection. Given its construction and the materials used, I anticipate this watch will provide reliable service for a considerable time, especially considering its intended use as a dedicated running tool rather than a do-it-all smartwatch.

Accessories and Customization Options

The Garmin Forerunner 45 Watch comes with the essentials: a charging cable and basic documentation. Garmin offers a range of replacement bands for this model, allowing users to personalize the look or replace a worn-out strap, including options beyond the standard silicone. For instance, switching to a different color band or even a fabric option can alter the feel of the watch for different occasions or preferences.

While it doesn’t come with specialized attachments like performance sensors or different watch faces directly bundled, its compatibility with the broader Garmin ecosystem is a significant advantage. Through the Garmin Connect IQ store, users can download additional watch faces, data fields, and widgets to tailor the display and functionality to their specific needs. This level of customization, while requiring an extra step, means the watch can evolve with the user’s training demands.

Pros and Cons of Garmin Forerunner 45 Watch
