B. Customer reviews:

So I've had this watch about a week now and I love it! The build quality is awesome and you can tell the Japanese Workmanship is still going strong.

Looks - I think the watch looks great. It is quite big on the wrist but that it looks good for today's standards. It is looks like a heavy duty watch that was given to designers to make elegant. If I had to make a car analogy, I'd say it would have the same feel as if Lexus made a heavy duty truck.

Workmanship - The quality is great. The hands align perfectly on the mark. The second hand ticks where the second hand is supposed to tick which I find annoying if it doesn't. (I've seen omegas that don't even align properly.) The minute hand also moves slightly every time the second hand ticks, the quality is definitely there.

Functions - Calendar, Timer, Chronograph, Alarm 1, Alarm 2, and of course Atomic Time syncronization. There is also a dual time zone function which is very helpful (home time zone and away time zone, you just press a few buttons and it switches them vice versa). The only problem is that if you want to see the current date, it will show the date of the away time zone. This is slightly annoying as to see the current date and time, the zones would need to be set to the same city. The calendar function however would be more helpful to real pilots (which I am not) as they will probably actually land in the away time zone.

Weight - This watch is a good weight, not too heavy, not too light. It is well balanced. This pretty much means that you should expect the non-titanium (i.e. stainless steel) version to be very heavy!

Illuminating hands - at night the illumination is pretty good. There is ample surface area of illumination making it pretty easy to read. The illumination seems to die down pretty quickly however though I haven't tested about how long it lasts. (The watch hands can illuminate briefly in the daytime when you are out in the sun and then walk into a normal lit room, I don't mind it personally.)

Sliding Rule Bezel - I like the function and I think it is really useful. If you take the time to learn this old school calculator, it is really neat and handy. It is best for multiplication and division, it doesn't do addition or subtraction.

Eco Drive - It is hard to tell how well this works, but so far so good.

Overall - I love this watch, it is rugged yet elegant. It also has an extremely impressive set of bells and whistles. The titanium looks good but also makes the watch light enough for wearing all the time without having to think about it. I give it 4.7 stars. Nearly Perfect.
