Nowadays, watches are no longer regarded as mere time tellers. With a variety of additional functions, digital watches in particular are especially practical and popular. Completely different in some cases, a digital watch usually shows the time directly with changing digits instead of hands compared to its analogue sister.

In the following sections, we will focus on the classic digital clock with direct digit change. For our product comparison, we have compared six different models and worked out the most important aspects to consider when making a purchase.


  • Digital clocks show the time with the help of changing digits. Because of this reduced form of display, digital watches often have space for additional functions.

  • Digital clocks with additional functions can already be found in the low price range. And only the more expensive watches are specially made for seniors, i.e. for patients with impaired vision and dementia.

The Best Digital Clock: Our Picks

Buying and review criteria for digital clocks

In order to find the perfect digital clock for you, we have worked out some buying criteria that you should consider when buying. In order for you to make an objective and well-founded purchase decision, these criteria should make it easier for you to compare individual watch models.

The relevant criteria for a comparison include:

Field of application / use

Do you want to use your digital clock as an alarm clock, decoration idea or simply as a clock? Depending on what you want to use your clock for, you should make sure that the clock meets the corresponding characteristics.

If you want to use your digital clock as an alarm clock on your bedside table, for example, the design, alarm sounds and snooze mode may play an important role. However, if the digital clock is only to be used as a decoration in a room, you might want to pay attention to the design. However, if you only want to use your digital clock as a clock that is easy to read, the display with the numbers plays a big role.


Many digital clocks are like small computers. They often have hidden functions that you don't know about if you don't look into them first.

Functions of digital clocks can range from a date display and alarm function to a snooze mode on digital alarm clocks. Make sure you know which functions are relevant to you before you buy.


Digital clocks come in a variety of designs and shapes. Their appearance varies enormously, and they attract attention. With the help of different shapes such as rectangular, square, with pointed or rounded corners and many more, the modern design of the digital clock can be combined with any decoration idea.

Not only the shape varies, but also the display board. There are digital clocks with a display that you can imagine as a small PC display, as well as clocks whose display consists only of large LED digits that can be read clearly from a distance.

Power source

Since digital clocks use numbers to display the time, they need a permanent power source. Digital clocks can be powered either by batteries or by a USB connection.

Before you buy a digital clock, you should decide whether you want to buy and dispose of batteries every now and then or whether you want to use a charging cable to power your digital clock from a wall socket. It is also important to find out before you buy whether the charging cable, adapter and, if necessary, batteries are included in the scope of delivery.

Since a digital clock does not have hands or a dial, the time can be displayed in a very large and simple way. This simple form of time display offers plenty of space for other display functions on the rest of the display.

Digital clocks are also highly recommended for senior citizens because of their large time display. For older people, special models are offered with reduced additional functions, but with easy handling and particularly large displays.

What types of digital clocks are there?

Digital clocks are offered in many different versions and designs. There are several stationary digital clocks in the form of alarm clocks, table clocks or wall clocks for the home. In addition to digital wall and table clocks, there are also popular wristwatch models for outdoor or fitness use.

Furthermore, many clocks in the public sector, for example at railway stations or on trains, are also digital. In fact, digital clocks are also installed in most cars.

What does a digital clock cost?

The price of digital clock is usually determined by the design, although many still have a manageable price. The prices of digital clock can range from low to high. The following table should give you an overview.

Price range Available products
Low-priced (8 - 15 €) various alarm clocks and table clocks, already many additional functions
Medium-priced (15 - 25 €) many table and wall clocks, with additional functions
High-priced (from 25 €) extra clocks for seniors, with additional functions for visually impaired and Alzheimer patients

Our ranking shows that good digital clocks with additional functions are already available in the low price range, but also in the medium price range. Thus, many digital alarm clocks, table clocks and wall clocks are offered at relatively low prices. Only extra senior citizen clocks are usually high-priced because they include extra functions for older people. In contrast, there is a digital clock for every budget.

How does a digital clock work?

Digital and analogue clocks essentially only differ from each other in the way the time is displayed. The way they work is largely identical.

Briefly explained: digital clocks usually use a quartz movement to measure time. An oscillating quartz is made to oscillate by means of electrical voltage. The resulting oscillations are translated into a second cycle, which is then transmitted to the display instrument by means of electrical impulses. The display instrument now shows the time. The display instrument can take various forms. Most modern digital clocks have an LCD display.


Digital clocks can be very versatile and make your everyday life easier with useful functions such as an alarm clock or temperature display. It is important that you are aware of what you want to use your watch for and which functions the watch should have integrated for your purposes before you buy it. The design of the clock can also play a role if you want to use it as a decorative idea, for example, because it should match the style of the room.

Good digital clocks with additional functions are already offered in a low but also medium price range. And only extra senior citizen clocks are available in the high price range because functions for older people are integrated. In addition, and apart from the price range, the digital clocks come in different shapes and designs, for every taste.
