Rating : - How to use slide rule
OK. For those who bought this watch because it looked neat, but had no clue what it is to own an aviator watch, here is an example of how to use the slide rule.

1. Lets say you are at a restaurant, and your bill comes out to $55. You wander what is 15% tip. Take the outer dial and align the number 15 on the outer dial to 10 on the inner dial. That will be your tip percentage. If you want to give 20% align 20 to the inner 10. Now, find 55 on inner dial. You should see about 82 for the corresponding outer dial. Divide 82 by 10. You get $8.20 which is your tip. Now, when you take some one out for a date, you could look like you actually use the bezel.

2. TAX can be calculated the same way. Just align the tax percentage on the outer dial to 10 on the inner dial.

3. You are on a road trip with rug rats. You have 200 miles to go and you are traveling at 70mph. The back seat monsters asks "are we there yet." You move 70 on the outer dial to the top arrow, where inner dial is 60. Find 20 on the outer dial. Corresponding inner dial is the amount of minutes to your destination. In this case 170. You are not done. Check the inside of the watch. on the outer edge of the face, you should see hour marks. 170 should correspond to 2:50 hours. Now tell the monsters that it is going to be another 2hours and 50 minutes so go to sleep.

I hope these will be useful for someone. As for negative reviews I have seen,

1. If you don't realize that almost all watches that are considered higher class than Casio Sports watches don't have lights, you don't deserve anything like this. Are you going to give negative reviews to Rolex because it does not have a light?

2. This is aviator watch guys! If you make them smaller, you will not be able to read or use the slide rule. If you can't realize that, buy different watch.

3. There is about a page explaining how to use the slide rule. But, since this is aviator watch, they probably expect you to know how to use E6B. Otherwise, hope my review helped.
