Design submitted by Logan from the USA.
This watch design is Logan’s response to two challenges: 1) measure time not using hours and minutes and 2) develop more creative analog watches.
This watch concept displays the time only as hours, with up to three decimal digits of precision. For example, 09.750 = 9:45, 04.333 = 4.20, and 12.817 = 12:49. Even just reading the first decimal digit provides a quick approximation of the time, since 0.1 = 6 minutes (so 12.8xy = 12:8*6+ … = 12:48 + …). Major divisions of the hour, such as 0:30, 0:15, 0:20, etc are also easy to recognize or remember.
This is a purely analog watch, with the hours and three decimal digits painted onto four rotating rings. A rectangular hole in the steel case reveals the time.
This watch is for the mathematically inclined and for people who like to explore different ways of thinking about the world.

I neglected to mention in my description that the rotation of the rings is not continuous — instead, they jump for digit changes. (If rotation were continuous, you would see blanks instead of digits much of the time.)

Logan is back 😀 I want decimal hours! It’s time that time gets decimal. Decimal system will conquer the planet, hahaha!
I was about to say, the fun area (where you can see things move) is too small in comparison to the case, but actually its cool when the rest is hidden… keeps the secret and creates a cool minimalistic watch face.
This watch is like an analog watch without dial: you get an abstract value which gives you a rough time at first and when you get used to it, you’re able to tell the time more exactly. I like this watch because I visualize the minutes already… And if I really need the exact time, I just multiplicate by 6. Good exercise 😉
Case and straps are ok, a bit too traditional for me but ok.
5*/y without hesitation.

Thanks, Sam! I hear you about the case and straps. I was conflicted about whether to make them traditional or more unusual, but I think my personal preference is to leave the focus on the digits.

I really like the “Decimal Hours”-appraoch and also the case, but would prefer different straps, too. The kind of straps I would have in mind would be more like the straps on the Kisai Keisan. I think a plain surface and shape would support the idea of focusing on the Digits even more.

With straps like Keisan, would you keep the face round or make it a (larger) square? And, if you really want plain straps, would you prefer a square face with Sensai-style straps? Thanks for your feedback, kleenerthor.

I think the face should be kept round to still have a contrast to the rectangular hole showing the digits.
When looking at the watch from above (like on your design sketches) the shape of the straps and links should be like the Keisan straps. Viewed from the side the straps should be as flat and plain as the ones from the Sensai watch, with the face looking like being put on top of the straps.

I think its kind of simple but cool. I would add some words before the time display like ” time now is”…. but blank empty is cool too, more elegant probably. Simplicity is the best. Love decimal. Add back lighting function.

Thanks, Fridaus. What do you prefer, back-lighting or phosphorescent paint for the digits?

glow in the dark for sure, must be energy saving, hmmm 😉

I love the shape, design and time telling as is. The only thing I would like to see is an option with either shiny or flat black for the watch.

Thanks, Čina! With a shiny or flat black body, would you keep the digits white-on-black, or would you change to black-on-white? What would you prefer?

I recently submitted a similar idea with time telling in a mathematical fashion (I went fractions and percentages, but decimals are also a really good idea) so this one is a natch 5/y! Kickin’ design, Logan!

Thanks, Cory! I also submitted a fraction-based design, so it seems we’re thinking alike on this. Either approach would be quite unusual in the watch world, I think.

OMFG! Do want! Seems to be a decimal virus around here. I give you *****YES because 4,5 arent possible. Why 4,5? It looks too 80s. But with the right price, its mine.
