Emerald Geneva

This model of a complex mechanical watch contains many of the most complex "complications" found in real watches, plus refinements found nowhere else. The displays maintain the look and feel of a real mechanical watch, but with considerably more complexity than possible in real mechanicals and with the time and location accuracy of a modern computer.

Best Watch Ever!

I wish I could strap the Geneva to my wrist, but having it on my iPhone (for free!) is good enough.

Fantastic

Absolutely beautiful. I use this a lot, as a professional astronomer and for my own interest.

At Last! A Geeky but Cool Wristwatch!
FSanders

For years, I've desired a wristwatch that would show sidereal (star) time. Such watches are very rare and expensive, and have the disadvantage that, if you're wearing one, then you don't have your regular watch for ordinary civil time. (You could wear two watches, regular and sidereal, one on each wrist, or else two on one wrist--but in either of those cases, forget about ever getting a date for the rest of your life; dual-capability watches are currently unavailable, as far as I can tell). So I was intrigued when I found this app. I was leery at first, but after I used it I discovered that it's just what I was looking for. It shows sidereal time, Sun and moon positions, and so forth, just as if it were a very high-end mechanical watch costing thousands of dollars. In fact, it does a number of things that would be impossible to build into any physically realizable mechanical watch. You have to use it to believe how geekily cool it is. Since it's on my iPhone, I've always got it with me just as if it were a wristwatch (or more accurately a pocket-watch), with an immediately available display that's actually bigger and easier to read (including in darkness) than any actual wristwatch display would be. You can have your cake and eat it too, with this app: Satisfy your Inner Geek by keeping this discreetly on your iPhone, and still have a decently good chance of getting a date with some nice girl.

Wow!

So much info on one watch. I was happy to pay just because I now have access to accurate NTP time.

Excellent

This is an absolutely amazing time keeper! It has every complication you could imagine and then some. I would have given it a perfect score for it's accuracy and features but had to deduct a star because some of the features are small and difficult to read. If you are a fanatic about watches and time in general, this app will not disappoint. I find myself studying and referring back to the many functions continuously throughout the day. I'm very happy with it.

EPIC watch app! If you want an accurate analog watch/clock app this is the one to get

This app is simply amazing. I'm a watch geek and I like to keep my collection set to the second, or at least check them when I put one on in the morning if I don't set it. Up until now I was using my iPhone clock with a simple clock app to set the time. I was starting to get upset with all my watches because they were gaining or losing time almost every time I checked them. Something wasn't right! I realized that even though the iPhone automatically synchronizes to the cell phone tower that clock in the AT$T tower can be seconds or even MINUTES off. They don't bother to keep them accurate because it isn't worth it to them to bother. Frankly, they just don't give a frak. I was using the free Emerald Time app to check the iPhone for accuracy but it is harder to set a watch when you have to convert a number to a second-hand's movement. You really need to have both clocks be analog to do it quickly and easily. Unfortunately Emerald Time does not have an analog face -only a digital one. This app is worth it just for the analog clock face but it does SO MUCH MORE. It's just simply amazing. The only thing I could ask is an option to switch the second hand from a smooth sweep to a 1/sec tick which would make it easier to set my watches that have that -although the smooth sweep is better for setting the Rolly. An option to change back and forth would be nice! I'll give it a 4.9 star and round it up as it isn't a BIG deal. Oh, and maybe make the second hand a little easier to see in "night" mode. Those two would be nice, though, as updates in the future... Can't think of anything else to add other than the impossible wish that the app could actually "fix" the wrong iPhone time :( Boo on the apple side for that FAIL. Can't blame the developers for the rules they must labor under and the limitations of the phone itself -or at least the way it is locked up. This app probably does half a million things that I've not even figured out yet!

amazing watch

Simply amazing for people who are interested in astronomical clocks. For $0.99, it is a sidereal deal.

The graphic is fantastic on Retina Display in new update!
Alireza A.

The watch is very nice and shows lots of information and have plenty of controls hidden in the analog view. In new update, the graphic is high-resolution and the watch is fantastic on retina display of iPhone 4. I suggest adding a page that shows the handful information of the analog watch in text.
