My new favorite watch. When this arrived everything was already set. I did not have to figure out how to take into account which year it is and which month. is it a leap year, and so on. I love the slide rule. Yes the numbers are very small, but I can read them using my glasses without any issues. Taking full advantage of all the slide rule capabilities will take time. But many of the basics are there and very easy to use. The alarm is not very loud, I tend to be a light sleeper, but I would not count on this waking me up. The local time feature (2nd time zone) is another nice feature. So easy to travel and simply set it to the local time. This keeps your home time intact. Note that the alarm uses your home time zone and NOT the local time. This watch offers so much and it is an Eco-Drive. It is also a big watch, close to as big of one I would like to wear and it has some heft to it. You will know you are wearing it.
