During today's earnings call covering the first fiscal quarter of 2015, Apple CEO Tim Cook shared some new details on the prospective launch date of the Apple Watch. According to Cook, Apple Watch development is currently on schedule, and the company is planning to ship the device in April.

Development for Apple Watch is right on schedule, and we expect to begin shipping in April.

When the Apple Watch was announced, Apple gave a vague "early 2015" launch date for the device, making it unclear when it would actually ship. Several rumors recently pointed towards a March launch date for the device, but it appears it will actually begin shipping out to consumers a month later, in April.

Cook confirmed that the Apple Watch's April shipping date was within the expected range of early 2015, which Apple considers to be the first four months of the year. Cook also said there are some amazing apps in the works for the device, and he mentioned that he couldn't live without the Apple Watch.

My expectations are very high on it. I'm using it every day and love it and can't live without it.

Now that we know when the Apple Watch is expected to launch, the only unknowns about the device are battery life and its cost. Rumors have suggested that battery life will be somewhat disappointing, lasting approximately 19 hours during "mixed use."

Cost is also up in the air, aside from a known starting price of $349 for the lower-end device. Pricing on the middle tier version is unclear, as is pricing for the high-end gold Apple Watch, which rumors suggest could sell for thousands of dollars.
