Stargazer Concept Watch Design

Design submitted by Logan from the USA.

Logan says: “You are sitting outside under the night sky with your sweetie. She points to the stars above and asks, “Do you know what constellation that is?”  You do.  Press the button on your Tokyoflash Stargazer and show her Orion in glowing LEDs behind the smoked black lens.  Turn the knob and scroll through all the constellations visible that night, searching together for each one in the sky.

Oh, and it also shows the time and date, and has a stopwatch mode where the date display is replaced by seconds and hundredths of a second, and you can set your latitude and longitude so the constellations are right for your location, and it’s USB rechargeable … but she doesn’t care about that.

The case and strap are matte-finish stainless steel. The LEDs are nearly white, with a slight yellow tint.  The smoked black lenses (center and four corners) are slightly curved to form slight bubbles rising above the case (not shown in the diagrams).

The constellation’s name is spelled on 16-segment displays, up to a maximum of six letters at a time (scrolling for longer names).  The time, date, latitude, longitude are show in groups of two 7-segment displays in the corners (time in 12- or 24-hour mode, date as DD:MM or MM:DD, adjustable).  When setting the latitude and longitude, “N,” “S”, “E”, or “W” is shown on one of the 16-segment displays.  There are also latitude/longitude presets for major cities, which can be scrolled through (to quickly set the coordinates for Tokyo, for example).

When you press the button to check the time, the watch will either display a random constellation visible that night at your latitude/longitude, or it will display the newest constellation visible to you, depending on which mode you have selected (random sort or date sort of visible constellations).  Turning a knob will scroll through the visible constellations.

The selection of constellations to include from the IAU 88 will determine the number and position of LEDs in the central constellation display.  To minimize the number of LEDs used, some of the relative distances between stars in certain constellations could be tweaked slightly so more LEDs could be shared between multiple constellations.  Optionally, a few LEDs could be multicolor to show visible planets, e.g., red for Mars.  These are cost considerations.”

    • Thanks, Sam. Of course, you are welcome and encouraged to make suggestions. I can imagine that your proposed layout would appeal to many people, and it’s quite nice in my opinion. The circles (which are supposed to have slight domes/bubbles) remind me of the planetarium, of huge telescopes, and of the sky — I chose them because they feel more like scientific equipment to me, but that’s just my personal view.


    • I like the one with circular displays better.

      It would be totally worth kudos if the 16-segment displays were red LEDs, like this: (but that would probably be very expensive or impossible to do in this age (even that display has a successor which is dot-matrix))


  1. Samukuns version looks a little too “silent”. But the original version has too many elements. Maybe the the perfect watch for me is somewhere between them. Ok besides that I think the starsigns are a cool thing. Interesting. You could add some astronomic and astrological information and make this a cool planetarium watch. The watch needs an internal compass and a gps. Cool thing!
