Chronograph watches A wide variety of chronograph types

Chronographs no longer just measure time.

There are a wide variety of chronographs, from those with additional functions such as measuring pulse rate and speed, to those with complex mechanisms that can measure lap times.

Chronograph watches Introducing various chronographs


A tachymeter is a scale for measuring average speed per hour.

A chronograph equipped with this is called a tachymeter chronograph.

If you want to drive 1km by car and want to know the average speed,
Start the chronograph as soon as you start the car.

At that time, the position where the chronograph hand points on the tachymeter scale is your average speed.


A telemeter chronograph has a scale that makes it possible to measure distances visually and audibly.

If you see lightning, press the start button at that exact moment.

Then press stop when you hear thunder.

The chronograph hands can then indicate the distance from the point where the lightning struck to the person holding the chronograph, i.e. the observer.

In other words, by using a telemeter, it is possible to measure the speed of sound at sea level.


Next to the memory, standard measurement numbers such as 15, 20, and 30 are written.

Based on this, you can press start to measure your pulse rate for one minute.

Once you have counted the standard number of beats, press stop.

At that moment, the number the chronograph hand is pointing to will be your pulse rate for one minute.

Azmometer Chronograph

Both the Pulse Meter and the Azmometer are models known as Doctor's Chronographs.

This asmometer chronograph is capable of measuring your breathing rate.

Just like a pulse meter, the respiratory rate is measured based on a reference measurement rate.

The standard number of measurements is 15, 25, etc.

It is used in the same way; press the start button, measure up to the standard measurement number, and then press stop when the breathing rate reaches that number.

At that time, the number indicated by the chronograph hand will be the number of breaths per minute.

Memento Dial

This is a mechanism patented by Universal.

It was originally installed in pilot's chronographs.

For this reason, it was originally called "Aero Compact."

As for functions, there is a 12-hour sub-dial which has nothing to do with timekeeping.

This is a function similar to a memo that records appointment times and other information.


This is a somewhat unique chronograph.

As the name suggests, the Parking Meter Chronograph is a convenient chronograph for measuring the time you spend parked.

The design is also made to resemble a parking meter.

What makes it even more interesting is that it's a disk that moves, not a needle.

The disk in the small window rotates once every 60 minutes.

And the elapsed time is displayed.

You can operate the watch by pressing the button above the crown to start and reset the watch.


This model is not very suitable for measuring in seconds.

Instead, it is a very useful model for measuring time down to the minute within 60 minutes.

This centre minute recording chronograph has a minute counter hand.

It is a type of chronograph that does not have a sub-dial.

When you press the start button, the center hand will begin counting in one-minute increments.

In other words, the hand makes one revolution in 60 minutes, so when you press the stop button, the outer marking indicated by the center hand represents the elapsed time.


This is a complex chronograph that is ideal for measuring lap times.

The "split-second" in the name means that the two chronograph hands start measuring at the same time as each other.

If you press the stop button halfway through, one hand will display the measured time.

By pressing the start button again, the stopped hand will start moving again and catch up with the other hand that is still moving, allowing you to start measuring again.

Yachting Chronograph

This "Yachting Chronograph" was made specifically for yacht racing.

The minute counter, called the yacht dial, is color-coded in 5-minute increments, allowing you to see at a glance the remaining time until the start.

Another feature is the Solnar Period Dial, an in-dial that displays tidal times.

Production Counting Chronograph

This model is a chronograph that measures the number of pieces produced per hour.

The measurements are taken using a tachometer, which measures speed.

To use it, first measure the production time it takes to make one product.

When you press the stop button, the chronograph hands point to a scale that indicates the number of products that can be completed per hour.
