Timex T123SX Simple Set Alarm Clock with LED Display (Silver)

This is the perfect alarm clock for people who change their alarm settings frequently. No need to advance the clock by 24 hours because you need to wake up at 6:15 instead of 6:30. Just use the top mounted keypad to enter the new alarm setting. Its as easy as 1-2-3, just like the model number. The large 0.9 red LED display is visible from any angle and can be dimmed at night for sleeping. The buzzer alarm has both loud and soft settings and the gentle wake system increases the alarm volume gradually to wake you gently. The battery back up system maintains the time and alarm settings during power interruptions.

    Great features, mediocre quality I am one of those people who don’t have the luxury of a regular time to wake up, and this is complicated by frequent travel that has me getting up early in the morning at different times to catch flights. When you have to frequently change the alarm settings on an alarm clock, the crude method used by most clocks makes the process annoying and tedious.Years ago, I found a product with the Micronta brand (from Radio Shack) that was called the VoxClock, and it was microprocessor based, instead of being built around a clock chip. This allowed the designers to include a keypad for direct entry of time and alarm settings, and the clock also used a voice synthesizer to speak the time (a feature that I never used). This clock was great, and included multiple alarm settings and tones (e.g. for more than one person to use). However, the microprocessor firmware was somewhat buggy, and the clock’s microprocessor would crash and require resetting far too often, and after resetting it was necessary to set times again and reconfigure it. I went back to a traditional digital alarm clock that has served me well over the years.Still, I kept looking around for a replacement alarm clock that had the VoxClock’s keypad entry of time and alarm settings.I finally ran across a product designed and manufactured by SDI Technologies, a company in New Jersey that has manufactured transistor radios, stereos, clocks and such since 1956, under the names RealTone, SounDesign, and for brands such as iHome, Timex, Barbie, Hasbro, Disney, etc. This is a keypad settable digital alarm clock that goes by the model number T123, sometimes with a suffix such as ‘SX’, depending on which brand name it is sold under. It seems that the Timex version is the most popular, but they all seem identical except for some of the the iHome ones which apparently come with different case colors instead of the standard matte silver color.But be careful……some versions of this clock are WITHOUT the keypad, otherwise looking just the same, and they set the time and alarm using the more traditional buttons that need to be held down while the time scrolls slowly. I have even found many instances (including on Amazon) where the description says ‘direct time entry’ but the photo shows the non-keypad version. Just be careful when you make your purchase!And indeed, even though I purchased from Amazon on the product page used for this review (which uses the iHome brand name), the actual clock I received was in a Timex box. There is nothing on the outside of the clock that shows the brand, except a tiny sticker on the bottom. I opened my clock up (reason for this later) and inside the name molded into the plastic and on the circuit boards was “SDI Technologies”.Anyway, on to the clock itself. The clock is in a matte silver colored plastic case, measuring 6.2″ wide x 5.8″ deep x 2 high. The four digit red LED display is 0.9″ tall, a large display compared to most alarm clocks. There is a switch on the side which allows setting the display to two levels of brightness, and I found that in a bedroom the dimmer setting is good. On the brighter setting, it would be better when used in a brighter/sunnier location.Overall, the clock’s appearance is pretty nice. The top inlay area is matte black, and this is where the keypad is located.The keypad itself feels rather cheap, and the tactile feel of the keys when pressed is not the greatest, but I found them to work well enough. And it is not like they are computer keyboard grade, needing to be pressed hundreds of times per day.The time and alarm entry procedure is very quick and easy. There are two buttons on the left side of the keypad for TIME SET and ALARM SET. You hold down the one you want for a couple seconds until the clock beeps once, and the display is cleared and reads only “0”. Then you press the numerical portion of the time or alarm setting, e.g. 7 – 3 – 0 for 7:30, then follow this by pressing either the AM or PM key to complete the entry (you need to wait about 1 second after pressing each number key, as the clock rejects the time if you try entering the numbers more rapidly). The time is normally displayed, but you can press ALARM ON button briefly to show the alarm setting for a few seconds. The AM or PM status is shown by a red LED dot next to the legend “PM” that lights up to PM and is off for AM.You turn the alarm feature on by pressing and holding the ALARM ON button for a couple seconds, and the clock indicates that the alarm is enabled by turning on a red LED dot next to the legend “ALARM”. The alarm will sound at the same time every day. Next to the ALARM ON button is an ALARM OFF button that you use to turn the alarm feature off, so the alarm will not sound every day. As previously mentioned, to check the alarm setting, you press the ALARM ON button briefly.When the alarm…
