getDigital Binary Wrist Watch for Professionals with LED Lights - A Black Digital Clock That depicts The time as Binary Code

Pros: 1. displays time in real binary 2. no "crib sheet" numbers for the LED. 3. simplistic/futuristic design. 4. appears durable. I have used it nearly continuously for a while now and it shows absolutely no signs of wear. 5. light and comfortable enough to wear for extended periods of time. Cons: 1. difficult to read in the dark...you can't tell if it is "101" (which is 5) or "1010" (10) or differentiate between "100100" (40) and "10010" (18) since only "1"s are illuminated and "0"s are left dark (meaning that you can't tell the position of the "1"s. 2. hard to set the time because there is no "blink" after holding the mode button for 2 seconds (seems that there is an LED buried under the face that is supposed to indicate that it is in "set time" mode). Oh, and another thing...there is no indication for AM/PM...not a big deal as we should already know whether it is morning or evening, but it would have been a nice addition. 3. only time displayed and only for 5 seconds...no date, no alarm, absolutely nothing else. 4. not even water resistant...disappointed about that. 5. face is simple plastic and is easy to scratch. 6. still unsure about the reliability...it may have gone off by 1/2 to 1 minute over a couple months, but I will have double check and reset all the other clocks in the house and see which ones are the culprit. I must say that this definitely looks cool and will go over well with any nerdy/geeky people. The minimalistic design is great and it is comfortable to wear. Durability, so far, has been exceptional. The only thing on this point that could be better would be some sort of water resistance and a scratch resistant face. The face is just simple plastic and is easily scratched (so far no issue). The battery should last a long time since it only displays the time for 5 seconds. This isn't an issue for me, but if you don't know binary, then you will have to push a button more than once to add up the numbers in your head...which leads me to another issue. This watch is difficult to read in the dark or when it is getting darker. The relevant LEDs light up, but the nonrelevant LEDs don't and when it is dark, you have no idea where the non-lit up LEDs are. This can lead you see the wrong number (see the example above). Talking about the LEDs...when setting the time, you are supposed to get a "blink" to indicate that the watch is in "adjust time" mode. The problem is that there is no blink...because the LED for that seems to be under the front face next to the hours. Basically it has been covered up. Other issues are that the watch face is simple plastic and looks like it would be easy to scratch, so be careful or wear your watch on the inside of your wrist. The band is adjustable and seems to be within the normal range for people's wrists. I use a middle setting and my daughter uses the 2nd hole...so this should fit just about everyone. One biggie is that it is not water resistant...OK, waterproof to "x" meters deep would have been nice, but water-resistant should be a gimme. So far no problems, but I worry about going out in the rain... OK, things to make this better...you have two buttons...why? Both buttons do the same thing. Having other functions would be nice...AM/PM indicator, alarm, world clock (where you can set the watch for other time zones), etc. There are so many ways to make this watch better, but for the price, it does what it is supposed to do, is light and comfortable to wear, and so far and appears like it should last. I'll come back and do an update after some more time.

Perfect !!! Exactly what was displayed and what I expected. I love how I have to think to know the time. Good form of distraction.

Difficult to correct time

Good quality and batteries are still running even years after I got it. Very cool and good quality product!!

Learning binary code, so this is a good way to help teach myself! Setting the watch to the correct time was easy. The directions might be a bit off? It said the H would flash and it didn't.. it took me a few tries to figure out how to set the time but I got it. So far so good, and very aesthetically pleasing!

Very cool and unique watch in terms of design, specially for those in the technical fields and are familiar with binary code. Once you learn how to read the time properly, then you’ll enjoy the watch even more, which is pretty easy to pickup. The watch face is more towards the smaller size. So, it’s great for those who prefer small watches or for those with smaller wrists. The band feels soft and comfortable.

I really wanted to like this watch, unfortunately it would often reset itself to 12:00 which makes this watch absolutely pointless. Then it would ocassionally stay lit up, like it was "stuck" and sometimes it would just flash, then reset. I thought maybe it's defective? So I requested for an exchange, and the replacement was even worse! Returned the second one, kept the first. I had thrown away the first original box, so I didn't think it was possible to return as well (otherwise I definitely would've). Also wished it would stay lit longer. Heed my advice, DON'T BUY THIS WATCH. Really cool idea; however, very poorly made!

This watch is unique fun and quirky it tells the time in binary code which can be hard to read for beginners but once you do learn how to read the time with this watch you can suprise all of your friends and also it is an eye catching watch i wear this watch and alot of people ask me how do i tell the time with that or what is that? so i rate this watch a 5/5 buy this watch if you want a fun time the watch is also decently water resistant also quite durable as well. able to handle a few scuffs,bumps and scratches

There are two A5 instruction sheets inside the box, one in English, one in German. The watch is easy to set up. You merely hold down the Mode button for about 5 seconds, then use the Adjust button to set the correct hour then the correct minute. I made sure to set the minute at the same time as a minute was updated on my radio-controlled clock. I have had the watch for about 3 weeks. It has kept excellent time, the minute on the watch being updated at the same time as the minute on the radio-controlled clock. Apparently, the watch runs on two CR2032 batteries, which you change yourself if you have a small screwdriver. The strap is black plastic, quite thick, and quite wide. I find it comfortable. I received my watch for less than £17 poiunds, and it seems excellent value for the price. Note that it is not waterproof. The face is not illuminated, so it can be quite hard to read in bad light. The time is not displayed permanently. When you press either the Mode or Adjust button to obtain the time, the LEDs remain lit for 6 seconds before turning off again. Initially, this can be too short to determine what the time is, but you soon learn to use tricks. For example, if the 32 minute LED is not illuminated, but all of the LEDs to the right of it are illuminated, then the minute must be 32-1 = 31. Again, if the 8 minute LED is not lit, but all others are, then the minute must be 63-8 = 55. Other reviewers have said that they have received comments from other people who see it in use. No-one has yet commented on my watch, but I use it strictly as a watch rather than as a conversation piece. I enjoy using the watch and wear it whenever there is little likelihood of rain. I am glad that I bought it.

De tijd op dit horloge is alleen leesbaar voor iemand die het binaire talstelsel begrijpt.

I came across this watch by accident on Amazon and knew I had to get one. It's a unique item, looks very stylish and isn't nearly as hard to interpret as it might appear. It is quite durable and I've only had to replace the battery once in the 2+ years I've had it. I think this watch could have some future value on the collectables market so I may get another and just store it.

Quería hacer un regalo pero que no fuera lo típico, y como mi amigo es informático, y sabía que le podrían gustar este tipo de cosas, me animé a mirar relojes binarios. El problema de estos relojes es que hay muchos y muy baratos, y no sabes si puedes fiarte de la calidad. Si hubiera sido para mi a lo mejor probaba con el de 3 €, pero siendo para regalo, al final hice lo que suelo hacer cuando tengo dudas, me fui a amazon.con y alli este reloj es el más vendido de estos modelos, tiene un montón de opiniones positivas, y por este motivo aunque el precio es más alto que el de otros, me decidí a comprarlo. Sobre el reloj, había leído opiniones que decían que para hombre era algo pequeño, a mi no me lo ha parecido. Es muy ligero, pero mucho, y el diseño es muy cool, si bien hay que tener en cuenta que es un complemento evidentemente friki. Importante destacar que para leer la hora debes pulsar el botón de encendido y las luces permanecen unos 5-6 segundos encendidas, después se apaga. No estaría de más que tuviera posición encendido/apagado de los leds, en lugar de un tiempo prefijado en que éstos se mantienen iluminados. Con la práctica es suficiente margen, pero al principio alguien que no esté muy acostumbrado al sistema binario tendrá que encenderlo un par de veces para sumar los minutos. Este es un reloj binario de verdad, con 4 leds para las horas (8 / 4 / 2 / 1) y 6 leds para los minutos (32 / 16 / 8 / 4 / 2 / 1), a partir de cuyos valores mediante sumas sacas todas las horas y minutos del día, que es donde le van a ver la gracia todos aquellos que entiendan el sistema. Lo digo porque me parece que hay otros modelos que venden como binarios, pero lo que hacen es meter 12 luces para las horas y 59 para los minutos, y no se trata de eso, simplemente son relojes leds, con otro diseño, más o menos bonitos y llenos de luces, pero nada de binario…. Por otro lado, gracias a que las luces están apagadas la mayor parte del tiempo, las pilas durarán una eternidad. La configuración no es literalmente como se indica en las instrucciones, en ellas se dice que pulsando durante 2 segundos el botón correspondiente, las luces parpadean y en ese momento ajustas la hora. En realidad, si parpadean lo hacen de manera apenas perceptible, a simple vista siguen encendidas de manera normal. Con lo que, en la práctica, simplemente pulsas el botón superior, cuentas dos segundos y directamente ajustas la hora con el otro botón. Vuelves a pulsar el botón superior y pasas a ajustar los minutos…. En fin, a mi amigo le ha encantado, tiene reloj para muchos años, y por este precio, lo recomiendo. Un saludo.
