Step 2: Remove the hands and the movement

With careful and with the help of the screwdriver remove the hands of the face of the watch. Then remove the movement from the face of the clock.

nice tweak !!!! loved it .. i just made mine .. "a reverse motion clock"..thanks for the awesome instructable

when i was in high school for some reason the clock in my geometry class starting going back words one day, a few days later it was evident that it would no be replaced nor would it go the right way so i made a formula to get the correct time out it based on the actual time, the current time on that clock and a function to simulate the reverse action of the clock. my teacher was pretty impressed because most of the class werent all that bright lmho

It worked! Thank you so much! I'd never done anything with clocks before so your instructions were a HUGE help :) This makes the perfect present for nerdy me to give to my nerdy boyfriend :) Thank you again! :D

I've done something similar to this :)

I've changed the "casing" of the clock to a photo holder and printed out a new "face"

However it really is hard to get used on reading time using c-wise clocks >.<

If according to Einstein The Theory of Relativity is E = MC2
then in my opinion and if there will be proper conditions so The reverse theory of Relativity should be MC2 = E

Reversal of hands trace time of ancient mariner
By Sanjay Nath
Bhubaneswar, March 6,1998 : He prefered the hands to defy tradition : to trace their way backward.
For Mr. Nisith Bose, a writer by profession, turning time hands in an anti clock route was a child hood dream. Bose new Einstein’s Thoery of Relativity which explores the possibility of travelling back in time. he realised that science had not sufficiently explored it.He believed that the idea is not just confined to the imagination of writers like H G weiis who toyed with the concept inthe classic novel, The Time Machine and he was convinced that he could translate theory into reality. he has invented a clock that moves anti-clockwise and gives accurate time. Bose, a pst gratuate in english from Shantiniketa explains his invention to curious visitors The Anti Clock is not the offspring of the brain of a scientific genius claims bose, but the result of creative thinking of a writer His point is seconded by his educational background He does not boast of a degree in sciwnce.Learnig the rudiments of the job job was a self taught task. He decided to move away from academics to a world of tick -tocks. Bose quite his job as a lecturer at Rani Sukadei Women’s Collegeto start a watch shop near CRP square in Bhubaneswar.
Custmers gradually trickled in and he fingered the hands for an added insight. He tinkered around with watches of all shapes and makes till he understood the inner story and logic of its machanism. The unusal watch is the result of four years innovative renonation as he chooses tolevel his achievement.
Born in Puri Dham, in Orissa, Bose believed that the concept of time is relative. It changes with situations, moodsand people . The clock forsed him to ponder about the past and veered his interest towards history. “Ancient time may not have been similar to how the immagination of people colours it.”says Bose. But the entire exercise of looking backis educative, he claims. His belief : Hindsight helps one remeber one’s root. After

About the Maker
Nisith Bose was born on 1st July, 1961 in Puri Town, popularly known as Jagannath Dham, Orissa. His father Suresh Chandra Sinha was a city watch maker of repute and his mother is a housewife. He studied at different schools and colleges of the state of Orissa and later went to Gurudev Rabindranath Tagore’s Shantiniketan for higher study. He completed his MA Degree in English Language and Literature in the year 1984. At Shantiniketan his teachers were late Dr. Sisir Kumar Ghose and Dr. Saurin Mitra. After completion of M.A. degree he started his career as a journalist and worked mostly for Oriya regional dallies like Sambad, Pragativadi, Paryabekhyak and Sambad Kalika. He is a satirist and a popular columnist and has many popular published columns to his credit. For his contribution to Oriya literature, he has been awarded several times by many reputed cultural organizations of the state of Orissa. Nisith Bose claims that he had invented The Reverse Clock in the year 1998.

Why Reverse Clock? Since 1991, soon after I quite my job as a sub-editor for news desk of Pragativadi, an Oriya daily newspaper published from Bhubaneswar, I decided to be in the world of tick-tocks. As it was a childhood dream for me, I preferred to turn the time hands in left direction to defy tradition. Much before I set myself for the renovation, I had sound knowledge about the Universal Magnetic Field. That, the earth acts like a huge magnet with its axis inclined at about 11 to the axis of rotation and the magnetic poles being on Bothia Peninsula and South Victoria Land. Gradually, I learned about the irregularities which occurred due to the presence of intense electric current in the upper atmosphere and local magnetization of rock strata. I also learned about the 67’s discovery which claimed of isolated magnetic poles. For further enquiry, I went through the laws invented by Ohm. The Only task which I undertook was to reverse the magnetic field. However, after a long innovative renovation I did it. It was during the morning hour of 26th February, 1998 the new watch was born and broke the age old concept of time. In the interview with The Asian Age, which held a few hours after the birth of the new clock, I said, “I knew about Einstein’s Theory of Relativity which explores the possibility of traveling back in time.” Because during renovation, I have thought a lot about the mechanical and philosophical sides of the work. As the concept of time is relative, it should not move in one direction. In my opinion, the perennial TIME stands still. Watches we use in day to day life is mere a device. It was invented for commercial use of time. The perennial TIME is perhaps the biggest concept. It is perhaps bigger than the space. Thus, it has either no direction or it has many directions. Take one example. From a certain point if somebody moves towards north so time runs in that direction for him. On the other hand if one moves towards south so time obviously runs with him in that direction. So I believe that the clock is the result of creative thinking of a writer. What I actually claim is that if it can move in the right direction, it can also move in the left direction and that is what exactly I have been observing in the character of TIME. When I say, possibility of traveling back in time, I am consciously aiming at an added insight. I don’t say we shall move backward physically rather if we could reverse our mentality and try to ponder about the past and veered our interest towards history so that the entire exercise of looking back may save us from moral as well as spiritual decay. The act of reversing the time hands has given me much pain because the germs of the age old concept of time have entered the tissues of my body and have danced with my pulses. But as there was no other possible way, I took the only alternative I had before me. Good or bad, sooner or later the concept of reversing the time hands is totally new on the globe and it is being cultivated for the first time in the soil of Orissa, the land of Lord Jagannath. I claim the incident should be recorded in different books of record for future reference. NISITH BOSE 26th Feb, 1998

Those whose backward clocks stop may have used alarm clocks as victims for mechanical hilarity. Many alarm clocks have a "ramp and pawl trip" for the alarm so that when the backward clock runs to the point where the time and the alarm coincide, the clock motor has to force the alarm setting gear train to follow the time gear train in reverse. At this point many clocks will stop until you move the hands to a different time, but will again stop at the alarm set time. Confusion can enter the situation even more if you replace the hands in a different position than they were when you removed them. You can tell before surgery if this will be a problem by turning the time set knob backward to and beyond the time the alarm is set for. If there is much added resistance or the alarm hand moves backward (earlier in time) with the time hands, you don't have a good candidate for plastic surgery. I once did this hack to the electric time clock where I worked in the 60's. I was brilliant and a hero among my work buddies until It jammed and stopped in less than a minute because of the dreaded "ramp and pawl trip" mechanism it had. Know your patient!

I've done this before, but can someone tell me why it works? Is it the symmetry of the metal plate that causes the rotor thing to flop one way or the other? Because this is not reversing the polarity of the electro magnet.
Yes. It is reversing the polarity of the magnet. It's pulling opposite of what it did previously driving the lever (motor) in the opposite direction.
So the metal plate is itself a permanent magnet? Or at least has some residual polarity or something...
No! By inverting the electromagnet, the polarity of the motor is reversed. The gear in the circle at the end of the magnet turns the other way.
Thanks for your persistence... I drew a picture to summarize this instructable. The only change being made is flipping this metal core of the coil. Which appears to be effectively symmetric. So the polarities before and after should be identical. The orientation of the coil, plate and spinning magnet is not changing. I hope this is helping someone else too... I just signed up to post this, but some day I promise to post an instructable!

Okay... I assumed he had reversed the elecrical contact on the coil... Looking again, I realize this would not work. It would still drive forward, or not at all... I took the liberty of adjusting the photo of the plate to adjust the perspective to directly on. As you can see, it is not symmetric. The magnetic field would be a bit angled because of the shape of the magnet's ends. Because of the position of the drive magnet to the poles of the elecromagnet, the drive is effectively reversed.

glitchmaker (author)  LasVegas7 years ago
You're absolutly correct! Don't even try to change the contacts of the coil. The wires are to fragile. The core has a semi-permanent magent, so all you have to do is reverse the core.
 whoa whoa whoa....semi permanent (yes, I know it's an ELECTROmagnet, but bear with me for a moment)....does that mean that eventually the clock will stop ticking, given enough time?
 Given enough time, any clock will stop ticking… :)

does this also work on a wrist watch??
glitchmaker (author)  Meie5 years ago
It could be done, but you have to take the fact of the size of the parts in a wrist watch, and most of the times the electromagnet is soldered to the board.
thnx, i couldn;t wait and bought a cheap watch today... the magnet was a really small dot covered in plastic what was attatched to the wheels. so it was really impossible to reverse it.. but maybe i have more luck with an other watch. if it worked, i'll let you know

How 'bout we just put the cells in backwards? xD
In this type of movement, putting the cell in backwards just means that nothing happens. If the battery is correctly installed it runs, otherwise, nothing happens.
It would propably burn out the circuit...
Or, indeed, it becomes an instant smoke and flame device. xD is an indicator of humor? I knew about :)
I was kidding...the xD on the end is a laughing emoticon....

Hey.I have seen these reverse clocks here on instructables but never before in real life.However this week I saw one in action!It sure looks crazy but nice. Now Ive decided to make my own reverse clock as well. :)
frikkie frikkie5 years ago
Hey my clock is in reverse mode!Now I just have to get like a cool design for a case and a background!
Hey Glitchmaker, that's cool. I was making this and I was like, hey, I'm gonna make an instructable of this clock reversing procedure myself, check it out, right here at http://www.instructables.com/id/Reverse_Clock_1/

Again I had 5 minutes spare... This was a bit fiddly but not to hard. I love it. I might have to go around altering all the clocks I find. Thanks for posting it.
okay i have a problem. I have been working on this for quite some time (2 diferent clocks) and i still havent got this figured out. I followed the instructions, and it ticks backward, but my problem is that the second hand wont move! Any ideas on a solution?
glitchmaker (author)  reineingonyou5 years ago
OK, maybe the connection point of the second hand has become loose. Try very carefully with a pair of pliers the connection tighter. remember be very careful, small steps at a time until it works.

I've been trying to work out how to do this for ages as I have an old gag clock in the shape of a clover leaf entitled Murphy's Time which is numbered in reverse. After reading this it was done in ten minutes. Many thanks for the excellent instructions.
Andrew5467 years ago
Now do this on a clock without a second hand (for a more subtle effect) and watch you're guests confusion as it gets earlier and earlier as the night wears on and they can figure out why. xD I wonder if there's any way to do this to a digital clock...
for the second hand... just cut it off...
Or just don't put it back when you're reassembling it...
but then you would have a hole in the end of the rod.
