getDigital Binary Wrist Watch for Professionals with LED Lights - A Black Digital Clock that Depicts the Time as Binary Code

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.

It's a nice watch and it arrived in really good time (I used amazon's free shipping). My experience mirrored other reviewers - when setting the watch the instructions say it flashes, but it did not for me. It was fine though, if you are bright enough to have a binary watch you're probably bright enough to set it. My only negative comment may not come as a surprise - this watch is unisex but leans more towards men. As a female I have to have the watch on the smallest loop and it looks HUGE on my wrist - I will probably make a new strap for it at some point. There's no doubt people will notice I have this on which isn't the subtle look I was going for when I bought it. If there was a female version I'd recommend that to other women thinking of buying this, but alas there is not (unsurprisingly!) Overall it's a nice watch and has a neat, sleek look.

The watch is so comfortable to wear and quite light weight too. I always seek geeky (or bright coloured) watches, no inbetweens. Get digital scores extremely high on my geekometer and I love the reaction from friends. It's a great conversation piece and I love wearing and using it.

It's cool, but I can't understand why it keeps loosing time. I'll be clicking it to check the time, and it always seems off. Currently 5min slow at the moment, so I'm going to have to change it again, which I've lost count how times I've done, but feel like I'm an expert now.

Purchased this item as a joke gift for my girlfriend. I have been studying a Foundation Degree in Computer Science and have been boring her with the details of what i have learnt over the past couple of years. She seemed intrigued by the way in which computers functioned using the binary system so decided to get this for her. Its brilliant for people who are beginning to learn how to convert binary to decimal (although you may be waiting a while for an answer when you first ask them what the time is!). The top section of lights on the face of the watch are for the hour and the bottom set for the minutes. This watch will also fit people with larger wrists so its ideal for anyone really.

The watch would not go into setting mode no matter how long you held the mode, button so the time could not be set. After replacing the battery the watch wouldn't even display the time regardless of whether it was correct. Leaving aside the fact that the watch was faulty, battery replacement is awkward with a clip that is tricky to release and feels flimsy. I know you can't expect much for the price, but a watch that worked might have been a start!

Brilliant watch. Still learning to tell the time on it but it gets a good reaction when other people see you tell the time with it! The write up says its best for people who already understand binary. I disagree. It doesn't take long to understand. My only pointer would be is that the instructions say the lights will flash when setting the time whereas they actually don't, took me a while to realise but don't let this put you off buying it as I've told you now!

a bit of a gimmick but as its cheap i should say it is actually what it says it is very hard to read but through wearing it you get to learn how to add up the numbers quickly Only 4 stars not 5 because you cant distinguish between the numbers in the dark and the LEDs should probably give you more than 4 seconds to count up the numbers

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.

Très belle, très bien, bon sujet de discussion, franchement je conseil ! Mas Attentil' un peu dure a réglé.
