* '''What's my cadence? '''[[Cadence]]''' '''is one of the most critical and often overlooked aspects of running. If you get your Cadence right, many other things naturally fall into place. The SF-510 has an internal accelerometer and will display cadence, but there is no option for a [[Footpod]]. Typically an internal accelerometer doesn't do a great job, and the SF-510 seems superficially rather poor. Unfortunately, it is not possible to get the Cadence data out in a format that can be analyzed for accuracy, so I can't be sure how bad this is. (For some reason, Epson call Cadence "pitch" which is a little unusual and slightly confusing.)

The only bright spot in an otherwise dismal device is the SF-510's battery life, which I tested at 30 hours, almost exactly what Epson claim. I think this makes it a worthy contender for your money if you need a watch that will give more than 24 hours of running without recharging and without crippling the GPS accuracy. See [[Best Running Watch#Watches for Ultrarunning| Watches for Ultrarunning]] for more details.

* The biggest advantage of the SF-510 is its long battery life, lasting for 30 hours. This is a chunk longer than other devices can provide with their GPS fully on. Other devices can go even longer, but they have to keep their GPS off most of the time, which can produce vastly inaccurate results.

* '''Smartphone Notifications'''. Having alerts like incoming calls or text messages on your watch is a rather nice, though far from a core feature of a running watch.

* '''Alerts'''. Some watches will alert you when a metric is out of range. The alert for [[Cadence]] is really useful and one of my favorite features on other watches. Of course, you need a decent measurement of cadence for this to be relevant.
