    Jury is still out - killer features, but buggy software

  • 4/15/2015 1:10 AM Background: I've been very excited about this watch ever since I first read the DC Rainmaker review of it over the summer, and couldn't wait to get my hands on one. For the past 5 months, I've been training for the Pittsburgh Marathon, mostly with my Garmin Fenix 2. (I have also trained for and run races using a Timex Run Trainer 2.0 in the past.) The Fenix 2 has been a solid performer for me, but I found the connectivity features on the Timex One GPS+ to be extremely compelling, especially for marathoning and long outings on the trails--I, for one, don't enjoy taking a phone along with me in these scenarios just to stay connected. I talked up the One GPS+ so much that evidently my wife caught on, and I was pleasantly surprised when she gifted me one in time for Pittsburgh (an early birthday present). The following review is based on my experience with the watch after wearing it for 4 days, with 4 total runs logged (2 ten milers, and 2 short cool-downs). Quick Summary: Pros: Design Aesthetics / Light-weight / Messaging + Live Tracking work like a charm / GPS accuracy and fix time is excellent Cons: Bluetooth HR sensor connectivity a bit flaky / Battery life drains down fast / Stability - Watch subject to random reboots / Workout upload issues - data locked into phone if not able to upload via 3G Full Summary: If I could sum up my impressions so far in a one-liner, I'd say: "Awesome features and lots of potential...but, unfortunately saddled with unstable / buggy / just-generally-not-production-ready software." At least, as an engineer with experience designing both hardware and software, that's my view of it. It's not all bad--in fact there is a lot to like--and I am hoping I can come back here and update my review once some of the early issues I have experienced are rectified (via a software update). Pros (after 4 runs with watch): - The design aesthetics - this was a surprise bonus for me, as I really didn't have any expectations in this department. I knew the watch was big, and expected it to be clunky-looking on the wrist. But, to my surprise, the watch is very light on the wrist (feels more comfortable to wear than my Garmin Fenix 2), and the design is very sleek, with an absolutely striking screen. Lots of compliments and folks asking what kind of watch it is in the few days I have been wearing it. - Screen - As mentioned above, the screen quality is one of watch's standout features...big, bright, highly readable in sunlight. Easy to read during a run...even with four fields displayed. Has the look of a smartwatch, but with a ruggedized exterior. The touch screen functions fairly well and reliably once you get used to it. - Messaging / Live-tracking - This features have worked seamlessly for me so far. Sending/receiving messages and setting up contacts has been simple and reliable...very awesome to be able to compose a pre-canned "here is my location" message to selected contacts, and have them be able to click a link that will enable quick pin-pointing of location in a maps app or browser. Live-tracking also works well...the whole family got a kick out of tracking my stats while running during my couple of test runs. The live-tracking page was informative and easy to navigate. This would be such a cool thing to be able to share with friends/family while my marathon is in progress. - GPS lock time and accuracy - GPS achieved fix very quickly and appears highly accurate. Fix time seemed like it was 15 seconds or much less each time...and the GPS accuracy was very good over my two days of use (I compared it to the Strava route builder, and the distance measured on the watch was just about spot on to the map measurements). Arguably, the GPS accuracy is better than the Garmin Fenix 2 (which struggled with significant GPS drift issues initially). I will note that over one of my 10 mile test run, the Timex reported 0.09 more miles than the Fenix 2. But, the Timex correlated more closely to map database figures in this case. Cons (after 4 runs with watch): - Bluetooth HR strap connectivity - had a lot of trouble getting BT to sync during initial pairing with the watch. Then, during my first run, after confirming pairing and that I was reading HR data, the watch reverted to showing a 0 bpm reading (or no bpm reading) during my run. I had to go kill the run activity in progress, and toggle BT on/off, and start a new workout to finally get it to pick up the HR properly. On my second run, the HR data was all over the place in the first mile...though. I know some of this can be due to contact issues and/or static discharge issues, and that, to some extent, most chest-strap-based HR monitors can have issues with this from time to time. - Battery life - I'd say this wasn't a huge con, because my expectations were in-line with the marketing claims of ~8 hours of life with GPS + cell, and ~4 hours with GPS + cell + music. After all, supporting a 3G chipset doesn't come for free, power-wise. That's a worthy trade-off, in my view, as the 3G connectivity is certainly the killer feature of this watch...and it is in-line with what you would likely get from your typical smartphone. That said, I was surprised when after about 1 hr 40 mins of running that my battery life had dropped from near 100% to 30-something%. During this time, I had GPS + 3G enabled, but no music playing. Granted, I had tried to upload my workout data several times (unsuccessfully--more on that below), so perhaps this was an additional drain. For mid-pack and beyond Marathoners, there would seem to be a very plausible chance that the battery life might not hold up for the length of the run (esp. if playing music, also). - Stability - this is a big one. The watch rebooted twice during my second day of heavy use...once during my 10 mile test run, and once after the run while trying to upload the workout data. The first reboot was a big bummer as I was holding down a great pace during my training run. And, even though the live tracking session I started had summary statistics captured for the run before the reboot hit...there was no data left on the watch that could be analyzed or uploaded afterward. It was all lost.In contrast, in my experience with the Fenix 2, data is often recoverable (and resumable) if there are sudden data tracking interruptions or shutdowns (due to a critical battery level, for instance). In fairness, this isn't the first time I've had a GPS watch reboot on me (the Fenix 2 started doing it when vibration alerts are enabled...evidently causes a current surge on the battery). But, the prospect of the watch randomly rebooting during a Marathon, where one would rely heavily on real-time data being captured, and also on the data for post-race analysis, is a scary one. In my case, I was able to resume a new activity while still running, and the watch picked it up and remained stable throughout the remainder of the run. Until a subsequent reboot once completed. - Inability to upload workout data / data locked into phone! - this is just as big as the stability issue for me, if not bigger. On my second day of test runs, I had trouble uploading both of my recorded runs. I currently have both Strava and Runkeeper enabled for sharing, and the watch would simply report that the workout failed to upload--try again (or something to that effect). I eventually found that you could access the Data Upload area under Workouts and force a retry. Subsequently, one of the runs successfully uploaded on retry, but the other (more substantial) run failed to upload even after multiple retries. In this case, the watch will just sit in a seemingly infinite loop reporting that it is "Uploading..." but never succeeds. I suspected a low battery level could be coming into play, so I plugged the watch into the charging cable and let it attempt to upload for 10+ minutes to no avail. I rebooted the watch several times, and toggled on/off airplane mode, and then retried some more. Still no luck. I did confirm that I could send/receive messages on the cell network just fine during this time, and I even was able to upload new test workouts that were subsequently captured...just not the one main workout I was interested in. I suspected perhaps a corrupted file, but the data and all the split times, etc., are viewable for the workout history on the watch. But, what really compounds this failure to upload issue for me is this: apparently, the only way to get your workout data off the watch is over the air via 3G! There is not backdoor via USB. When I plugged the watch into the USB cable, with the expectation that I would just manually upload my workout data file to Strava, I was *shocked* to see that the watch does not expose the workout/activity data when mounted as USB mass storage. Rather, it only exposes the music folder. This blew me away, as I can't fathom a high-end watch such as this not exposing the workout data over USB, by design. This implies that there is a very real chance of your data getting locked into the device if there are any issues with 3G upload over the air (case in point for me), or, if the owner simply decides not to renew 3G service after the year of complimentary access. Also, this means there is no easy way to bulk delete data from the watch by simply deleting workout files via mass storage mode. Post-workout data analysis is serious business for many Marathoners and other runners and athletes, alike (recreational or otherwise). In the high-end watch end of the market, my view is that you simply *must* enable users with reliable ways to access their data without forcing them to pay for it and/or forcing them to rely on unreliable upload mediums (such as 3G). So, this is a huge drawback to the watch, and something I hope gets addressed in a future update. In conclusion: I really want to love this watch...that's how awesome the design aesthetic is and how compelling the features are. Unfortunately, the software is currently holding it back, and it needs to mature before I could recommend that others purchase this watch. I had read about schedule slips in getting this watch out to market, and it appears to me that the watch was still pushed to market too soon, as the software is clearly not ready to for prime-time, yet. I know this can be fairly common in the industry (the Fenix 2 was no exception), but for a watch at this price-point (or any price-point, really), one must be able to have stable operation (aka, no random reboots) and reliable access to data. Otherwise, it is way to risky to rely on this watch for serious training and racing. My first instinct would normally be to return the watch to Timex and pick up something else...but, for now, I'd like to find out what Timex's software upgrade schedule is, and whether some of the issues above can be remedied in any way. That's how compelling this watch's potential is...enough so that I am willing to give Timex the benefit of the doubt, and hold out for a more mature software release. I will gladly update my review with new information once I have it, particularly if the issues can be remedied. But, until that happens, buyer beware.
