A tachymeter-equipped watch can be used to measure distance by timing the travel over the distance while the speed is held constant. The tachymeter scale is rotated to align with the second hand at the start of the length to be measured.

What is the purpose of a tachymeter on a watch?
What Is A Tachymeter? A tachymeter is a type of watch complication used to measure the speed at which the watch’s wearer travels over a fixed period of time. Tachymeters are typically featured on chronographs, specialized watches that feature multiple stopwatch functions in addition to the traditional watch display.
What are the 3 dials on a watch for?
A chronograph watch typically has three dials to register the time elapsed – a second dial (also referred to as a sub-second dial), a minute dial and an hour dial. Positions can vary based on the watch manufacturer.
Does a tachymeter bezel rotate?
Some tachymeter scales are on a rotating, indexed bezel. This allows two additional modes of use: The tachymeter bezel can be aligned with a free running second hand, and, more subtly, can be used to find the average speed over longer times/distances.
How do you turn off a tachymeter?
When you pass the first marker, start the chronograph by pressing the button at the 2 o’clock position. Press the button again to stop the chronograph once you pass the second marker. Finally, follow the chronograph’s hand to the tachymeter scale to find your speed measurement.
What’s the point of a chronograph watch?
The Chronograph’s main function is to allow a comparison of observation between a time base and, before the electronic stopwatch was invented, a permanent recording of the observer’s findings. For example, one of the first applications of the chronograph was to record the time elapsed during horse races.
What means chronograph?
Definition of chronograph
: an instrument for measuring and recording time intervals: such as. a : an instrument having a revolving drum on which a stylus makes marks. b : stopwatch also : a watch incorporating the functions of a stopwatch.
What is a bezel on a watch?
What Is A Bezel In A Watch? The watch bezel is the ring that encircles the crystal glass to secure it in place. It is one of the many parts of the watch case. Bezels are usually metal but they can come in other materials such as ceramic.
What do the small dials on a watch mean?
Subdials are the mini-dials that sit on the watch face or dial. Also known as auxiliary dials, subdials serve different functions—like tracking lapsed seconds, minutes, and hours, the phases of the moon, a second time zone —across mechanical and specialty watches like chronographs, calendars, and GMT watches.
Is Bulova a good brand?

What does 10 20 30 Mean on a watch?
A sub-dial with markings 20, 40 and 60 shall be revealing seconds or minutes while the markings 10, 20 and 30 are meant to register 30-minutes for a stopwatch.
What is a 24 hour subdial on a watch?
Instead the 24 hour timer subdial correlates to the main time. For example, if the time is 8:00PM, then the 24 hour subdial will display 20 which essentially is 20:00 with 24 hour time. It’s helpful at allowing the user to quickly read AM/PM at a glance.
What is the difference between chronograph and chronometer?
In short, a chronograph is a complication to measure short periods of time and a chronometer is a high-precision watch, certified by an official organisation. They are different but not antagonist concepts.
What is the outside ring on a watch for?
Most watches with a rotating outer ring can be used as a tachymeter. This will allow the wearer to calculate movement based on travel time. Start the timer at a distance indicator and note when the person or object being measures completes whatever unit of measurement you’re trying to calculate the speed of.
Why do some watches have a rotating bezel?
Rotating the bezel is done to set a particular time of reference. The most common approach for a diver would be to rotate their bezel so that the 12 o’clock marker signifies when it is time to exit the water.
What is a Speedmaster watch?
Omega Speedmaster is a line of chronograph wristwatches produced by Omega SA. While chronographs have been around since the late 1800s, Omega first introduced this line of chronographs in 1957. Since then, many different chronograph movements have been marketed under the Speedmaster name.
Should the second hand move on a chronograph watch?

Which is better analog or chronograph?
The basic difference between analog and chronograph watches is the functionality – analog watches tell the time, with two hands showing the current minute and hour, whilst chronographs feature a ‘complication’ (that’s the in-the-know term for any functions a watch has other than telling the time).
What’s the difference between a watch and a chronograph?
The first thing to understand is that a chronograph is not a watch in and of itself. Rather, a chronograph is an additional function (referred to as a complication in the world of mechanical watches) that a watch indicating hours, minutes, and seconds can perform.
Can I wear a chronograph with a suit?

To find out what they look like, then check out our collection of luxury Fileteado GMT watches at Franck Dubarry.
