We set out to build a wrist watch that would synchronize the natural rhythms of the sun and the moon with modern time, show the times for sunrise and sunset, moonrise, moonset and lunar phase along with exact digital, military and analog time.

MAKING COPERNICUS BETTER WITH A TITANIUM UPGRADE

At the get go I wanted to produce the Copernicus in titanium, but GPS signal reception issues strongly suggested to put it in a non metal case, like CF or polycarbonate.

Only one watch engaging GPS and embedded in a titanium case is in existence, the Seiko Astron which retails for $2600 plus. It uses GPS only to synchronize time, date and time zone. That tells you how tricky this is to pull off.

Keeping eyes and ears open our HK team have sourced some new GPS technology that along with a bezel and lug nut re-engineering allows us to produce the Copernicus in titanium. I like this a lot and have asked a few customers about it. They all agree it is the way to go. Much more durable and than either CF or polycarbonate.

However, this change coupled with the tariff and trade war with China, which has caused both delays and increased component costs, dictates that the price must be raised. Hong Kong is not as cost effective as they once was, they have evolved into one of the most sophisticated manufacturing hubs on the planet, and prices have followed.

Add all the time data Copernicus brings and it warrants a higher price. I have yet to get a fixed cost estimate on the titanium version, but I am sure that the original MSRP of $995 will not hold. I am hoping we can settle on $1495, with max being $1995. Maybe $1695 hits the right spot? I’d welcome any thoughts you have on the pricing.

POWER - MAKING IT LAST

Powering a clock or wristwatch has been a challenge since day one for the makers of them. On a cloudy day not even the sundial could keep time.

Capturing the nuances of solar and lunar time requires chip technology and electricity. Even though Ancient civilizations were familiar with it, taking electricity for granted is less than a hundred years old. Not until 1999 was GPS available for use in watches.

The Copernicus employs a state of the art chip, PCBA and battery technology. Both the AMOLED screen and GPS receiver are hungry for power.

To keep the AMOLED consumption in check the solution is to shut it off after a certain viewing time. The Copernicus allows user to set it from 10 to 90 seconds. For checking time 15 seconds is plenty. If you start pushing buttons to review time data or set it, the display will stay on for the duration of it.

To turn it on, a controlled wrist flick from vertical to horizontal position, or pushing any button, will make the screen come alive.

Collecting a GPS signal requires a lot of power. Why smartwatches using it to track movements rarely last for more than hours. We use it to catch only UTC, LAT and LON, a process that normally takes 90 seconds. Copernicus can be set to catch a signal only when manually engaged, but it can also be set to automatically catch one daily or weekly, perfect for when you are on the road. You do want to be outside to catch it properly. Once engaged the GPS will search for 10 minutes before giving up. Either way it will alert you with a beeping sound and a screen display as to what is going on.

My testing goal is to crash Copernicus, so far no luck. I charged the black fully a week ago, set it to a 60 second display time, collected a GPS signal several times and used it for photography. Not until a week later did it go down to 3 bars. I am hoping we’ll see up to 30 days on a full charge, but it is too early to tell. To charge it you simply place it on top of the included charging pillow. One thing is clear, the way you set it up and use it will affect battery life.

FOUR VIEWING OPTIONS
For each of the 13 different screen colors you can choose between, there are four viewing options. Switching between them is done by one simple button push.
As I go through the operations kudos to our programmer for making Copernicus user friendly. Some good thinking went into it. 👌

BLUE ICE, the Nordic way

This could easily be my favorite Copernicus. A crisp blue and white AMOLED display in the pearl grey case with the SUN bezel and a matching nylon strap. Nice and casual, with an aura of quiet. Takes you to another state of mind just by looking at it. As if everything is possible, if you can think it you can create it. The moment at hand is timeless.

Fall Equinox today, a key turning point in the solar year. Copernicus marks solstices and equinoxes with a checkered pattern in the outer dial and the push of a button will display the time data.

STOCKHOLM TODAY
Set with the neutral B&W screen with the red Night Vision screen engaging between sunset and sunrise.
The higher the latitude the longer each of the twilight periods are. Each represents the sun dipping 6 degrees further below the horizon. In the Copernicus we added the golden hour as well.

THEN IT HAPPENED

The prototypes made it to California, and they are cooler than I had imagined or hoped for. Our HK team did an outstanding job on the programming and operations. The AMOLED sparkles like the starry sky and the 44x15mm case rides very comfortably.

Copernicus has a lot of stories to tell, it knows time like no other.

First thing to test? Will it set itself by one simple button push? Take away the operational complexity imbedded in our previous collections? This is after all what the push for engaging GPS technology was all about. It has surely tested our wits and patience without mercy.

I took it down to Tourmaline Beach one afternoon, settled in the warm sand, gazed out at the sky, pushed the crown and held it in for 3 seconds. Moment of truth.

After 90 seconds it switched from HK time to SD time without a glitch, just like the doctor ordered. Spot on, wow. Or like one of our customers put it, the interface to the cosmos without any bu****it.

By picking up signals from 5 satellites Copernicus collects UTC and LAT/LON, then compares it to our city listing and adds relevant TZ and DST system. The solar and lunar data is calculated by our proprietary programming and is done for the exact coordinates.

It will automatically pick the nearest city from a city listing of 650. In 9 out of 10 cases this will be what you want. There are however locations where the signal collected is within nearly equal distances of several cities, possibly changing TZ and DST specs. Its first choice may not be what you want, so you can pick one of the 2 nearest cities or set it by LAT/LON.

They say good things come to those who wait, we must be proof of that and there is more to come. Within the next month we will update our Indiegogo campaign with images and videos of the operating prototypes on the wrist, even though the campaign will remain live 24/7.�

The Copernicus AMOLED screen

A sampling of some of the Copernicus screen displays and setting commands. You can choose between 12+1 different color screens along with the main type of display you want for daily viewing. From a pure spatial rendition of the solar and lunar time cycles to an information rich center display where natural cycles are represented in the two outer screen dials. We also added an option where the time digits are ghosted on top of the all natural display. Could be the favorite for many.

WATCH CRUNCH and Mr.RNG

Are you a watch enthusiast? A bonafide lunatick?

If so look up WATCH CRUNCH. I joined them awhile back and it is a place for people who care about their watches.
�Through it I met Mr. RNG, a lunatick par excellance. We got to talking and I sent him a V7, what would he think?

He made this review, certainly worth watching:

THE FIRST PROTOTYPE

Last Tuesday the first two fully operational Copernicus prototypes were delivered to our programmers office in Hong Kong. Very exciting. It has been a long and winding road, but I always knew we would get here. Maybe I’ll hop a plane to HK, join the hands on testing and meet our new team. I haven’t visited in almost a decade.

Ms.Yang sent me some pictures, this Copernicus is set with the sage color display and happens to mark the third cross quarter day, Lammas, August 7. Cool.

As always with prototypes there are refinements to be made, and we are checking and testing with a fine tooth comb. For example, for the SUN bezel we’ll have to rethink the use of LUME, get it to light up brighter. Those thin lines just couldn’t hold enough LUME material.

But we’re getting there, and that is truly rewarding. Thanks for all your support and patience.
