Garmin Forerunner 945 Watch Review

A Close Look at the Garmin Forerunner 945 Watch

As someone who spends a significant chunk of my life navigating diverse environments, from the grit of a workshop to the unforgiving demands of the outdoors, reliable gear is not a luxury; it’s a necessity. My search for a truly capable multisport GPS smartwatch led me to the Garmin Forerunner 945 Watch. This particular model promised a blend of advanced training metrics and robust build quality, aiming to be the central hub for tracking performance across a spectrum of activities. The need for such a device became glaringly apparent after a particularly ambitious multi-day trek where my previous basic fitness tracker faltered, leaving me with incomplete data and a gnawing sense of missed opportunity.

Upon unboxing, my first impression was one of understated robustness. The fiber-reinforced polymer bezel and Gorilla Glass DX lens felt substantial, suggesting it could endure more than just a few bumps and scrapes. It’s a far cry from flimsy plastic; there’s a reassuring heft that speaks to its intended purpose. While considering alternatives like the Apple Watch Ultra or some of Suunto’s offerings, the dedicated focus on athletic performance and battery life in the Forerunner line always kept it at the forefront of my research. The initial feeling was one of practical curiosity – would this device truly live up to the hype and my demanding usage?

Real-World Testing: Putting Garmin Forerunner 945 Watch to the Test

First Use Experience

My initial testing ground was a mixed bag of environments. I strapped the Garmin Forerunner 945 Watch on for my early morning trail runs, tracked a weekend spent doing heavy-duty workshop repairs, and even wore it during a downpour while testing some new waterproofing sealants. Its performance in these varied conditions was remarkably consistent. The sunlight-visible, transflective memory-in-pixel (MIP) display proved easily readable under direct sun on the trails, and the touch responsiveness remained reliable even with slightly grimy fingers from workshop duties.

The ease of use was a pleasant surprise; transitioning between sport profiles and accessing settings felt intuitive after a short initial setup period. I didn’t need to pore over an entire manual to perform basic functions. However, one minor quirk emerged: initially, the sheer number of customizable data fields for each activity could be overwhelming, requiring a deliberate effort to pare down to what was truly essential for immediate viewing during intense sessions.

Extended Use & Reliability

After several months of constant wear, the Garmin Forerunner 945 Watch has proven itself to be an incredibly reliable companion. It’s been subjected to countless sweat-drenched workouts, accidental impacts against metal shelving in the workshop, and the general wear and tear of everyday life. There are no significant signs of wear and tear; the Gorilla Glass DX lens has resisted scratches admirably, and the silicone strap shows no signs of stiffness or degradation.

Maintenance has been straightforward. A quick rinse under the tap after sweaty sessions or a wipe-down with a damp cloth is usually sufficient to keep it looking and functioning well. Compared to previous budget GPS watches I’ve used, which often developed screen glitches or battery degradation within a year, this model’s robust construction and consistent performance are a significant step up. It genuinely feels built to last, a crucial factor when you depend on your gear for critical data.

Breaking Down the Features of Garmin Forerunner 945 Watch

Specifications

The Garmin Forerunner 945 Watch boasts a 1.2″ (30.4 mm) diameter display with a sharp 240×240 pixel resolution, rendered on a sunlight-visible, transflective memory-in-pixel (MIP) screen. This combination is crucial; transflective displays are optimized for outdoor visibility, using ambient light to enhance readability while consuming less power. The case, made of fiber-reinforced polymer, houses a rechargeable Lithium-Ion Battery that offers an impressive smartwatch mode battery life of up to 2 weeks, a stark contrast to the daily charging required by many smart devices. When actively using GPS with music playback, you can expect up to 10 hours, and up to 36 hours in GPS mode without music. This is a critical differentiator for long expeditions or multi-day events where power outlets are scarce. The watch is also water resistant to 5 atm, meaning it can handle splashes, rain, and even swimming, a common requirement for triathletes or those working in environments with potential moisture exposure. Weighing in at a mere 50 g, it’s exceptionally light and comfortable for prolonged wear.

Performance & Functionality

Fundamentally, the Garmin Forerunner 945 Watch excels at its primary job: tracking activities with pinpoint GPS accuracy. Whether I was charting my pace on a winding forest trail or mapping a new cycling route, the satellite lock was consistently fast and precise. The array of sport profiles, from running and cycling to swimming and strength training, are comprehensive and well-configured out of the box. For triathletes, the integrated triathlon activity profile is a game-changer, seamlessly transitioning between disciplines without manual intervention.

Its greatest strength lies in its depth of data and analytical tools. Features like running dynamics (requiring a compatible accessory), VO2 Max estimation, training status, and recovery advisor provide actionable insights that go far beyond simple step counting. However, the sheer volume of data can be a double-edged sword; for the casual user, it might feel overwhelming. The learning curve for truly leveraging all its advanced metrics is significant, but for the dedicated athlete, it’s an invaluable resource.

Design & Ergonomics

The design of the Garmin Forerunner 945 Watch is purely functional, eschewing the sleek, fashion-forward aesthetic of some smartwatches for a more rugged, tool-like appearance. The black, fiber-reinforced polymer bezel and case feel robust, and the Gorilla Glass DX lens provides excellent scratch resistance. The five physical buttons, arranged logically around the bezel, are a deliberate choice that enhances usability, especially with gloves or when your hands are wet or cold.

While the silicone strap is comfortable for extended wear and durable, it’s a standard quick-release design, meaning it’s easily interchangeable should you wish to swap it for a different material or color. The 130-220 mm wrist size accommodation ensures a snug fit for most users. The display, though not the most vibrant OLED, is perfectly legible in all lighting conditions, which is paramount for outdoor activities where screen glare can be a major issue.

Durability & Maintenance

Garmin has a reputation for building durable devices, and the Forerunner 945 upholds this standard. After months of consistent use across various demanding scenarios, it shows minimal signs of wear. The 5 atm water resistance has been put to the test in heavy rain and through numerous swimming sessions without any ingress of water.

Cleaning is as simple as wiping it down with a damp cloth. For more intensive cleaning, especially after a muddy run or workshop session, a quick rinse under running water followed by drying with a soft cloth is effective. There are no complex parts to disassemble for cleaning, making routine maintenance incredibly user-friendly. Potential failure points would likely be related to long-term battery degradation, as is common with all rechargeable devices, or severe physical impact beyond its design tolerance, but for its intended use, it appears exceptionally robust.

Accessories and Customization Options

The Garmin Forerunner 945 Watch comes with essential accessories: a charging cable and documentation. However, its true customization potential lies in its compatibility with Garmin’s ecosystem and third-party accessories. For advanced metrics like running power or cadence, you’ll need compatible Garmin HRM-Run straps or foot pods, which offer valuable data but are an additional purchase.

The ability to download custom watch faces, data fields, and apps from the Garmin Connect IQ store is a significant advantage, allowing users to tailor the watch precisely to their needs. You can download detailed topographic maps for backcountry navigation or specialized training plans. The standard silicone strap is also easily swappable for leather, metal, or nylon bands, allowing for aesthetic personalization or functional adaptation to different activities.
