Clock hand meaning
Simply put, some analog watch typically consist of two main hands:the short hand known as the hour hand, and the longer hand,referred to as the minute hand.The hour hand provides information about the time in terms of hours, while the minute hand indicates the time in minutes. These hands work in tandem to help us accurately read the time on an analog clock.
Which hand is the hour hand and What is the minute hand on a clock
As mentioned above, the short and small hand is the hour hand and the long and big hand is the minute hand.When the minute hand is pointing to 12, it indicates that it is exactly on the hour. When the minute hand is pointing to the 6, it signifies that it is half past the hour.Minute hand is longer than the hour hand and moves at a faster pace, completing a full revolution around the clock face in 60 minutes.
What is the second hand on a watch
As shown above, the hand pointing to the seconds becomes the second hand, which is generally the same length as the minutes or slightly longer.The second hand is divided into small second hand and sweep second hand.
What is small second hand
A watch featuring a small seconds function situates the seconds display in a separate sub dial on the watch face, usually positioned at 6 o’clock. In contrast to the commonly seen central seconds position in modern watches, a timepiece with small seconds is seen as a more traditional choice, often regarded as a complication. Additionally, the inclusion of an hour hand further enhances the sophistication and functionality of such a watch.
What is a sweep second hand
The sweep second hand is a hand on a timepiece that is mounted concentrically with the other hands and can be read from the same dial as the minute hand.
What is the difference between the minute hand and hour hand?
The shorter hand on a clock is referred to as the hour hand, while the longer hand is known as the minute hand. The hour hand indicates the time in hours, while the minute hand displays the time in minutes. During a span of one hour, the minute hand completes a full rotation of 360 degrees, while the hour hand covers a smaller angle of 30 degrees. When the minute hand reaches an angle of 180 degrees, the hour hand corresponds to an angle of 15 degrees.
How to measure watch hand
Generally speaking the hour and minute hands appear as a pair rather than separately. To measure the length of the clock hand, you can first measure the length of the minute hand, from the middle of the watch hole to the end of the hand. Note that the watch hand length is a whole number or 0.5 mm, there is no 15.2 mm watch hand length.The hands are made of aluminum or copper-coated steel. If the watch hand is too long to affect timekeeping, you can consider cutting the watch hand short. This is because if the hands are too wide or too long, the torque force of the movement is not enough to move the hands. as shown in the figure:
Measuring the minute hand will give you the corresponding hour and minute corresponding length from the watch hand book.
How to determine clock hand
Step 1: determine the diameter of the opening face of the watch face, note that it is the opening watch dial. Openning face means the diameter of the face that the eye can see, not the watch dial diameter. Refer to the figure below.
The watch face diameter is 32.5mm,in the first dial version,the opening watch face size is 30.5mm,in the second dial version,the opening watch dial size is 28.7mm.
Step 2: calculate the length of the minute hand, the length of the minute hand is equal to (opening face diameter-1)/2. So if the diameter of the opening face is 30.5mm, then the length of the minute hand is (30.5-1)/2 = 14.25mm, according to the previous article, the length of the watch hand is usually a whole number or 0.5mm, so the length of the minute hand is 14mm or 14.5mm.
Step 3:calculate the length of the hour hand, generally speaking, the hour hand is 0.7 times the minute hand, so the length of the hour hand is 14×0.7mm = 9.8mm, so the length of the hour hand is 10mm.
Step 4: determine the length of the second hand, the length of the second hand is generally as long as the minute hand, but if the open surface is relatively large, the second hand can be longer than the minute hand about 0.5mm.
Types of watch hand
The different shapes of the watch hands in some way indicate the aesthetics and positioning of the watch brand. Many famous watch brands have their own characteristic watch hands, such as Rolex’s Mercedes watch hand and Cartier’s treasure blue arrow watch hand. Next, we will introduce you different types of watch hands to help you better appreciate your watch.
Arrow watch hand
Arrow hand are among the most recognizable because they point to the hours and minutes with arrow-shaped clock hand. This gives the dial an excellent and fast readability. They are often used on diving watches for better visibility underwater. You can see Arrow hands from on Omega’s Seamaster, Tudor and other brand watches.
Baton watch hand
Baton hands are the most common type of watch hand. They are also known as stick hands. They are characterized by their simple, slender, rectangular shape. Baton clock hand have a long stem attached to the center of the face, which allows them to move over time. Baton clock hands are typically used on dress watches and other watches with a more traditional design.
Cathedral Hands are a variation on the classic skeleton hand. The shape of the hands mimics the stained glass commonly found in Cathedral windows, featuring elaborate geometric details coated with luminous paint. A Cathedral hand usually has a larger hour hand and a thinner minute hand.Cathedral hands are suitable for use in vintage style watches.
A variant of the Breguet hand, the dauphine hand is an invention from the 1940s, named after the French word for prince. In the shape of a classic tapered triangle, the dauphine hands have an elegant appearance and is suitable for traditional style dress watches.
Mercedes hand takes its name from the three-pointed star of the hour hand, which looks like the Mercedes-Benz badge logo. This feature helps to distinguish the hour hand from the minutes at a glance. Especially the Mercedes shape area is more suitable for making diving watches like Rolex submariner if luminescent paint is added to it.
Pencil hands are a subcategory of sword watch needles, and their name describes their shape. Like a classic wooden pencil, these hands are long, thin and straight, with a small tip at the top. Depending on the width of the pointer, they may be solid or filled with and applied with luminous material.
As mentioned before, some brands have their own characteristic watch hands. The snowflake hand is the signature design of TUDOR sports watches. The snowflake hand features a snowflake shaped pattern on the end of the second hand. This snowflake pattern feature makes this hand popular among dive watches.
The sword-shaped watch hand is very similar in shape to the blade of a sword, with a very sharp tail and an overall long and thin appearance. However, the middle part of the hand is slightly wider. Cartier watches especially like to match the sword-shaped hands, especially the white Roman numeral dial with blue sword-shaped hands, which looks more advanced and clean.
In recent years, the Swiss company TR through high-tech technology will be tritium gas (rare gas H3) sealed inside the transparent vacuum tube coated with cold light material, tritium gas continues to emit low-energy particles times the cold light material absorbed to emit light.
The night light does not need to use any light source, to achieve zero energy consumption self-luminous. Tritium watch hand can adapt to extreme environments such as deep-sea operations, and glow for up to 25 years, so many diving watches have begun to be equipped with tritium watch hand.
In conclusion, understanding which hand represents the hour on a clock or watch is crucial for accurate timekeeping. We have explored the significance of clock hand movements, differentiated between hand types, and provided insights into measuring and determining the hour hand. By familiarizing yourself with these concepts, you will enhance your ability to read time with precision and appreciate the intricacies of timekeeping devices.
