I doubt it will be refreshed yearly.
Other devices have been upgraded because of displays, CPU/SoCs, radio standards (EDGE/3G/4G/LTE, for example), cameras,… basically all pieces of hardware evolution, some of which are due to outside influences.
The Watch has a plenty good display that's already Retina quality; maybe it could be upgraded with a rumored "enhanced sapphire" crystal, but that's about it. The SoC is powerful enough to do the job and won't be asked to drive highly detailed games. It doesn't have, and may never need, a cellular radio. It's not a good camera platform, either, whether for taking pictures (never mind editing and tweet-face-gramming them) or using video chat.
There isn't much that needs upgrading, then, is there? Anything you add, especially if we're talking about more pixels, cellular radios, and faster CPUs, is going to suck up more power. Then you'll need either a bigger battery or totally new battery technology, neither of which looks very likely for a while.
So, no, I don't think we'll see a yearly upgrade cycle. The Watch is being described as an accessory, right? Maybe it'll cruise along with incremental updates like the Apple TV.
We'll find out in 2016/2017/etc. My guess is as good as y'all's.
