Welcome back to our series, in “Common Watch Terms You Need to Know- Part 2″. If you want to read Part 1, you can click here as I explore the Monticello 5006A by So&Co Watches. Today, we will be exploring more watch terms which are definitely useful. But don’t just take my word for it. Read on and find out.
The dial is also known as the face of the watch. Usually used to display time, it can also display other pieces of information such as watch logo, tachymeter and other complications depending on the movement.
A sub-dial is any other dials other than the main dial of the watch. Usually, watch complications like day, date, calendar are placed on the sub-dials to differentiate between the time and other functions. For example, we can see from the Monticello 5006A that there are 3 sub-dials. The sub-dials include hour indicator on the 9 o’clock, date sub-dial on the 6 o’clock position and also a sub-dial indicating day on the 3 o’clock position.
Hands are indicators used to identify the time. It usually consists of an hour, minute and occasionally second hands as well. The hands will sweep above the dial, as it passes a certain index. Where the hands stop pointing at the index, tells the user the time at that moment.
The Monticello 5006A has an hour and minute hands, style and shaped like a baton. It is designed to glow in the dark under a low-light condition, hence the term luminous fill. Also, certain watches, like chronographs, has a specific hand, or chronograph second hand.
CHRONOGRAPH SECOND HAND
Have you ever noticed the second hand on the chronograph which doesn’t move? That is because the second hand is independent, and only moves when you press the pusher button. Pressing the pusher again will stop the second hand.
To reset the second hand, you just press the other push button, since there are two pushers on the side of the case. The second hand of the chronograph functions to measure elapsed time. Most chronographs have another smaller second hand, located on a sub-dial. This is to distinguish the chronograph second hand and the main dial second hand.
It is also called a “flyback hand” and was given this term because how quickly the hand returns to zero when the reset button was pressed.
The video below shows you the function of the chronograph second hand as he explains how to to use the chronograph complications. Check out the video by Watchfinder & Co.
A crystal is also called the window or glass to the watch, Its primary function is to protect the dial and its components from dust, debris, and other external environments. Usually made out of acrylic, it can also be made out of mineral crystal, sapphire or glass.
Each material has its advantages and disadvantages when it is being used to create the crystal of the watch. For example, because acrylic is relatively inexpensive, therefore is the most common material used. The mineral is more scratch resistant than acrylic but its slightly more expensive. Sapphire crystal is the most expensive but also the most durable among all the materials.
A bezel is one of the most commonly known watch terms on any watch. To summarize, a bezel is a metallic ring with the function to hold the dial and its components in place. This is also the place where the crystal sits on top, protecting the dial and its components.
The Monticello 5006A polished beveled alloy bezel gives it a modern & clean look to the watch. This is obviously seen when you tilt the watch to one side.
A tachymeter/ tachometer is a complication found also in the Monticello 5006A. Basically, tachymeter is an indicator used to measure speed over a distance. A tachymeter is just like the speedometer on your car dashboard.
Very common in chronographs, the user will set the chronograph second hand to zero and start the stopwatch.
Once the measured object passed a certain distance, the user manually stops the chronograph second hand. Where the hand stop, this will indicate the speed of the object measured.
