Any last questions we had about the Apple Watch were answered Monday afternoon.

During an event in San Francisco, CEO Tim Cook and other executives announced key details about the Apple Watch, including when it will go on sale, where it will be available, and exactly how much it costs.

Here's what we now know about Apple's first wearable device:

1. The Apple Watch will go on sale online and by reservation in Apple stores on April 24.

Pre-orders begin April 10.

2. The Watch will be available to customers in nine markets, including the U.S. The others are Australia, Canada, China, France, Germany, Hong Kong, Japan and the United Kingdom.

3. The cheapest Apple Watch -- the 38mm sport model -- will cost $349, as expected. The 42mm (which is the height from top to bottom of the watch) will cost $399. The most expensive version of the Apple Watch, called the Apple Watch Edition, will start at $10,000 and cost as much as $17,000.

4. On a full charge, the Apple Watch battery should last up to 18 hours. This is critical, since the Apple Watch needs to be continuously connected to an iPhone in order to work, which can be a big battery drain.

12. You can use it to work out. The Apple Watch will have a heart rate sensor and an accelerometer to measure body movements, including step count. The watch does not have GPS, which comes as a major disappointment to fitness enthusiasts.
