Comparison TFA 605008 vs TFA 602011

The format in which the time is displayed on the clock face.

— 12 hours. A format that enumerates individual hours (time intervals) from 1 to 12. Since there are 24 hours in a day, this numbering covers only half of the day. This option is traditional for hand dials (see "Dial type") — historically, the full circle of the hour hand corresponds exactly to 12 o'clock, and it is from this principle that both watchmakers and watch users around the world today proceed. However, it can also be found in other types of dials. Theoretically, this option may require clarification — roughly speaking, "7 o'clock — in the morning or in the evening?" — however, in the vast majority of cases, the answer to such a question is clear immediately, from the context of the situation. But when using an alarm clock (see "Functions / Capabilities") in such a watch, you have to be especially careful: if, for example, at 6 pm you set the signal time to 8 am, the alarm clock will go off at 8 pm, because the clock itself "does not distinguish" between morning and evening.

— 24 hour. A full 24-hour format, provides numbering of hours from 1 to 24 (more precisely, from 0 to 23, because exactly 24 hours are considered zero of the next day). Thus, when looking at the clock, in principle, there is no question whether we are talking about the time of "morning" or "evening": for example, 7.00 will unambiguously correspond to morning, and "7 pm" will be designated as 19.00. At th...e same time, we note that such clarification can be provided in other ways — namely, the 12-hour scale, which has additional indicators AM (ante meridiem, "before noon") and PM (post meridiem, "after noon"). Therefore, models with such modified 12-hour scales are also classified as 24-hour models in our catalog. This format is used in all types of dials, except for arrows.

— 12/24 hour. This category includes watches that have the ability to switch between a full 24-hour clock and a 12-hour clock with "AM/PM" qualifiers. Formally, both of these types of scales are 24-hour scales (and are described in detail in the relevant paragraph above); the same designation is used to emphasize the possibility of switching formats.

Among the functions in the table clock and radio you can find: alarm clock, snooze, voice notification, calendar, thermometer, world time, radio auto-off timer, time projection, dial backlight, case backlight, USB charging port, wireless charging gadgets, flashlight. More details about them:

- Alarm. The watch has a classic alarm clock that provides a sound signal at a customer-specified time. Of course, this function can be used not only for morning wake-up, but also for other warnings. However, the most popular way to use an alarm clock is to wake you up in the morning. In light of this, some models may provide a very specific way of disabling the alarm - for example, by installing a propeller in place that takes off from the clock when the alarm goes off; and some models begin to move at the same time as the signal, and you have to catch them. There can be many similar options, but they all follow the same principle: to push the customer to take active action and reduce the likelihood of falling asleep after the sound has been...turned off. Watches with original alarm clocks will be especially useful for tech who tend to wake up when they wake up, turning off the alarm and falling asleep again.

— Delay of the alarm signal (Snooze). As the name suggests, this function is designed to reschedule the alarm to a later time. Its meaning is that when a signal is triggered, the customer can literally move the alarm time by several minutes with just one click of a button. Snooze is intended primarily for tech who prefer to lie in bed for a while after the alarm goes off before getting up: it minimizes the risk of falling back to sleep and missing the time to wake up, while pressing the Snooze button is much easier than changing alarm clock manually. In some models, the delay time is fixed (usually about 5 - 10 minutes), in others it can be adjusted at will.

— Voice notification. The watch has a voice warning system. One of the most popular uses of such a system is to announce the current time at the press of a button; in some situations, this method of finding out the time can be more convenient than trying to look at the dial. Theoretically, other types of alerts could be provided - for example, a low battery warning; however, for a number of reasons they are rarely used.

- Calendar. The watch has a calendar function. This feature requires, at a minimum, the display of the current day of the month, but the matter is not limited to this: even in watches with pointer dials (see “Movement type”), the calendar can also cover the day of the week or even the current month, and in digital devices - also the year, the number of the week in the year and a lot of other information, including displaying calendar tables for each individual month. The calendar can also provide other functions, such as setting an alarm for certain days of the week.

- Thermometer. The presence of a thermometer function in the watch allows you to use it to determine the air temperature in the number. This function may be useful in cases where you need to maintain a certain microclimate - for example, if there is a baby in the house. Built-in thermometers, as a rule, are made electronic, which provides more than sufficient accuracy for domestic use. And in some models, the digital temperature display can be supplemented with a color one - for example, by changing the color of the housing backlight (see below for the backlight itself).

- World time. The presence of a world time function in the watch allows you to determine the current time in other regions. Most often, an additional dial is used for this, which is set in advance for the time of the time zone of interest and constantly displays this time; and in the most advanced models there may be several such dials. There are other ways to implement this function - for example, models with LCD screens (see “Dial type”) can provide quick switching between local time and a specified time zone. In any case, watches with a world time function are useful in cases where you regularly communicate with people from other time zones - in particular, they minimize the risk of being in an inconvenient situation by calling your interlocutor in the middle of the night or at another inopportune moment. On the other hand, today there are more practical ways to monitor standard time than desk clocks (for example, smartphones are equipped with similar tools); therefore, this function is rarely found, mainly in luxury models.

— Radio auto-off timer. A timer that turns off the receiver after a specified time. This way, you don't have to worry about turning off the device manually - just set the desired time and the receiver will turn off automatically. This can be useful, for example, if you like to fall asleep to music: by setting a timer, you can calmly fall asleep without worrying about wasting energy on “all-night” broadcasting (which is especially critical for self-powered devices, see “Power”).

— Time projection. The watch has a projector function. Thanks to it, the device is able to display various data not only on the dial, but also on various surfaces - for example, projecting information onto the ceiling or wall. In some cases, the projector mark is more convenient and better visible than the main dial. As the name of this feature suggests, the projector is primarily designed to display the time; technically, nothing prevents other data from being displayed in this way, however, for a number of reasons, such a possibility is rarely provided. As a rule, the projector unit is made rotating, which allows you to adjust it to different environments.

— Dial backlight. The watch has a dial illumination system. This backlight is convenient in low light conditions: it allows you to see the dial without using additional lighting sources (in other words, you can look at the watch even in complete darkness). Note that in this case we are talking about systems that turn on for a short time - usually for a few seconds while the customer holds the button; Constantly glowing symbols on the dial do not count as backlighting, although they can also be seen in the dark without any problems. And in some models, the dial illumination can be combined with the case illumination (see below).

— Case lighting. The watch has a case lighting system. Unlike the dial backlight described above, this function is usually not associated with the main functionality of the watch - it plays a decorative role and also allows the device to be used as a night light.

- Flashlight. The built-in flashlight allows you to use the receiver as a light source. Moreover, the power of such sources can be quite high, providing an effective range of several tens of meters. Usually this function involves a directional beam, but there are also diffused light flashlights.

— USB port for charging. The presence of a port for connecting a third-party gadget and replenishing its energy. Naturally, this solution is applicable when connecting a table clock to a 230 V power supply, and the speed itself will be mediocre.

- Wireless charger. Ability to work in Power Bank mode without using a cable. The gadget is charged wirelessly by placing the desired device on the charging area.

— Pencil stand. The presence of a pencil stand in the watch design. By design, such a stand usually represents a characteristic “glass”; its shape can be varied, but the dimensions are usually large enough to accommodate several fairly large stationery items. Therefore, despite the name, the stand can be used not only for pencils, but also for other items - pens, markers, scissors, etc.

Power supply methods provided in the design of radio receivers and table clocks.

- Batteries. Powered by standard replaceable batteries ( AA, AAA, type C, LR44, PP3, etc.). There are two main advantages to this diet. Firstly, a shrunken element can be quickly replaced; for this, of course, you need to have fresh batteries in stock, but it’s easy to take care of this in advance. Secondly, consumer devices are independent of outlets; this allows you to install them on almost any suitable surface, easily move from place to place, without worrying about the length and placement of the mains cable. Batteries, of course, need to be purchased separately, which slightly increases spending. However, many replacement batteries are also available as rechargeable batteries. Thanks to all this, battery-powered models are very popular today.

- Network. Powered by a standard 230 V network. On the one hand, this option eliminates the hassle of batteries, and on the other hand, connecting to the network is associated with a number of inconveniences: the power cord limits the ability to install a radio or clock in places where there are sockets nearby, moreover the device may interfere or simply not fit into the overall environment. Mai...ns power in watches is quite rare in its pure form - much more often it is used as a fallback option for battery-powered models: if the situation allows, you can plug the watch into an outlet and not waste the charge.

- Battery. Powered by an original battery that is not related to standard sizes. Like the batteries described above, this option provides the device with autonomy. However, the key difference is that the battery, as a rule, does not provide for quick replacement: a non-standard format makes it difficult to purchase a spare battery, and more often than not, it is generally made non-removable. Therefore, the main, if not the only, option for discharging is charging, which requires a connection to the network and takes quite a long time. As a result, rechargeable batteries are considered a less suitable power option than replacement batteries and are rarely used.

The colour of the characters displayed on the digital watch face screen (see "Watch Type"). Classic LCDs, most often used as such dials, have black characters — a variant familiar to almost anyone who has dealt with electronic watches. However, modern table clocks may provide other colour options — white, red, blue, green, orange(yellow), etc.; such colours are usually a sign that the dial uses permanently lit indicators and can be seen in the dark without additional illumination.

Some models of "coloured" watches are available in several versions that differ in the colour of the characters. But the colour change function, usually, is not found — it is quite difficult and expensive to provide such a setting in LCD screens that play the role of dials.
