Technological limitations have previously forced Garmin to create watch-style workout monitors that were clunky, heavy, and cumbersome, but the Garmin Forerunner 405 breaks that paradigm with its diminutive and elegant design. It has a watch face with a small screen, only two buttons, and wireless capabilities.

With the 405, you can not only wirelessly upload course and workout data to your computer, but even to other nearby units, all without the need for a USB cable. This makes it so easy to upload data, you’ll be eager to check out your workouts in Garmin’s included software or on websites like Motionbased. The simplicity of the two-buttoned Forerunner 405 may take some users time to get used to, especially given that previous models could sport up to seven different buttons. Once you’re used to the design and functions, however, configuring and operating the Garmin Forerunner 405 is a breeze.

There is also a short on-screen tutorial that plays the first time you start up the unit. This helps reduce the learning curve if you’re intimidated by all the options. The 405 model also has a bezel screen display, allowing you to scroll options by spinning your finger around the top edge of the watch. Luckily, depending on your preference, you can alter the speed and sensitivity of the bezel in the 405’s settings screen. The bezel can also be locked to avoid changing settings or screens accidentally, which is handy when you’re working out in long sleeves that can brush against the watch.

Another great feature of the Garmin Forerunner 405 is the speed and strength of the unit’s connection to satellite signals. The 405 locks on within seconds of being powered up, and keeps the signal for your whole run.

As for cons, the Forerunner 405 can only show three training fields on screen at once, as opposed to the four featured on other models. This is a result of the smaller, lighter design and is a small sacrifice, as most users probably won’t need the fourth screen anyway. It’s important to note that the Garmin Forerunner 405 doesn’t turn off, but goes into a “sleep mode.” Fortunately, it’s easy to keep tabs on your remaining battery life because the 405 gives you a percentage of battery remaining, offering a more accurate measure than the usual battery “bar” display.

Overall, the Garmin Forerunner 405 is a fantastic workout monitor, but is probably a bit steeply-priced for casual or recreational users. Opinions may differ on the user-friendliness of the bezel design, but everyone can appreciate its small size and light weight. The wireless data transfer features are a fantastic addition, sealing the deal to make the 405 a nice leap forward in the Forerunner line.
