Apple (AAPL -0.57%) is widely expected to launch its iWatch this year, which should include a wide range of health and fitness features. One analyst is offering up estimates for how the rumored product might fare during its first year. Morgan Stanley analyst Katy Huberty thinks that the iWatch could generate upwards of $17.5 billion in revenue over the first year, unless supply constraints hold back Apple's ability to meet demand. Huberty also expects Apple to price the device at $300.

Samsung (NASDAQOTH: SSNLF) didn't fare so well with its own $300 Galaxy Gear, although the company is likely preparing to launch a new version in coming months. Even though Apple may pursue a similar strategy of making the iWatch more of an accessory than a stand-alone device, Apple enjoys a much stronger "halo" around its products than Samsung.
