Tachymeter: How to Use One for Accurate, Speed-Based Calculations

Just like in the movies, two cars rev up their engines awaiting the checkered flag to come down and signal the start of the race. At the end of the motor path, someone holds up his chronograph knowing that the press of the tachymeter on the bezel of his watch will measure the speed of the cars over the distance. It is not the drivers in the car that have the power; it is the timekeeper, and ultimately, the tachymeter scale.


Luxury sports watches may have rotating or fixed bezels, according to preference. The real star, however, is the tachymeter. A tachymeter computes constant speed based on time of travel. The measure can be found on the rim of some analog watches with pronounced spacings on the dial. These spacings measure the speed over distance with a formula of

Where T stands for the measured time in seconds of constant speed over distance over one and multiplied by 3600 seconds divided by one full hour or multiply the number by 3600 seconds and then divide by one full hour.

Most chronographs feature tachymeters, yet many wearers do not understand how to utilize them to calculate time. If they do know about this function, they might be confused since the scales do not correlate to seconds, minutes, and hours. The style of the watch may also be a source of confusion; luxury sports watches come with rotating or fixed bezels, according to preference, but the rotation is of little consequence. It’s the spacing of the dial that’s key to making the calculation

A bezel that rotates is not the same as a tachymeter. A rotating bezel measures in increments from 0-60, whereas the tachymeter charts in increments of 60 to 400 or 500. One begins where the former ends.

 Americans use the Imperial system and will measure using miles. Europeans use the metric system, but as long as the units used maintain the same distance throughout your calculations the time will bypass cultural preferences.


Let’s say the person timing the race presses the tachymeter to indicate the race has begun and sees the tabulating hand pointing to 11 o’clock on the dial.

We’ll say the hand is pointing to 11 o’clock, so 55 seconds have passed since starting. The number on the tachymeter bezel adjacent to 11 o’clock is 65. This means the car being tracked is traveling at 65 miles per hour.

You can use this process to calculate the speed of anything traveling faster than 60 units per hour. Measuring slower speeds will require a little mental math; decreasing the unit of measurement can do it.

An example of using the tachymeter can include divers who use their divers watches to time how long it takes to reach a sunken ship or to return to the water’s surface.


While it is true that digital watches are tremendously popular, there is something to the time-honored tradition of a timepiece with a tachymeter scale. It gifts the wearer with self-reliance, allowing you to calculate what you need without leaning on technology or keeping close to an electrical outlet to recharge

The Exquisite Differences Between Chronograph & Multifunction Watches


Timepiece connoisseurs might be able to tell the difference between a chronograph and a multifunction watch, whereas a watch industry novice may be confused by their surface similarities. Both are sportier watches with some heft, and they generally have three smaller dials on the face of the watch. The difference lies in the details and how they function for the wearer.

Stop and watch a chronograph

Chronograph watches have a rich history, and some have speculated that they’ve changed the sports world for the better. Chrono- is the Greek word for time, and graph means writing. The name itself tells you this item is for recording time. Everyone from pilots to astronauts, and even the King of France in 1817, used the chronograph watch to calculate time.

Chronograph racing watches are popular with athletes who want to record their physical accomplishments. Chronographs first used in France in the 1800s before catching fire in the ensuing centuries as they were used to keep track of races and duels, thus doing away with gray areas and guesstimating. These time-keeping features, however, are kept separate from the standard time mechanisms via a pusher on the top or side of the watch. Timepiece enthusiasts understand the beauty of a chronograph design. A complex dial varietal may be coveted for its aesthetic layout or for more practical purposes.

Master the calendar with a multifunction

A multifunction watch is also known as a master calendar. While chronographs count the smaller details of the passage of time, including seconds, minutes, and hours, a multifunction watch is distinct in its ability to track the day of the month or week as well as the time of day.

Design and practicality

Chronographs and multifunction timepieces are considered big face watches for their subdials, up to three on the face, which their owners may not know how to use. For many, the draw is the design or popularity of this style, while the functions may be overlooked. This was particularly true in earlier centuries when many tried to keep up with royalty rather than the Joneses. Once a king of a country with a strong military declared a strong proclivity toward an object, it immediately became endowed in a luxury cache. These watches, however, serve practical purposes.

A multifunction watch can help when on an expedition to a mountain peak or when you simply lose track of time during an arduous task. The watch allows with a quick glimpse to the wrist to see the time and date which can be a gift when running to a meeting. This timepiece can keep you connected to the world and make sure you stay on track, and you’ll never slip too far into jetlag with this miniature calendar on your wrist.


A chronograph or a multifunction watch, offering practical and aesthetic appeal, are the top choice as sports watches for men. A chronograph records the smaller details of time, which is perfect for sporting events or setting personal records. Multifunction watches serve as calendars that allow the wearer to be completely punctual at the correct time and place. The King of France may have worn a chronograph, but both watches are fit for royalty and daily warriors alike.

Measuring Your Wrist Perfectly for a Watch that Will Make You Stand Out

A watch is a thing of beauty for men, women, and children. In order to appear polished and offer comfort and security to the wearer, the timepiece must fit correctly. Sizing is a top priority. It is important to avoid sliding down the arm and possibly losing your treasure. One cannot go by the fit of old watches, particularly ones with leather straps that shrink or may not have been correct in the first place.  There are also dimensions to consider when deciding if a watch is ideal for your wrist, including case diameter and thickness, alongside material quality. Your watch is a personal accessory that catches the eye, and the following brief guide will make sure you look exceptional with a perfectly fitted watch.

Touch method

One unscientific way to test the fit of your watch is to stick your index finger between the strap and your wrist. If a strap, or attachment, is too tight, it will leave an indentation. A perfectly fitted watch will allow your arm to have some breathing room and for the watch to have slight movement to ensure optimal comfort.

Ribbon method

A ribbon is a certain way to measure your wrist. Wrap the ribbon around your wrist and secure it with a strip of tape, then mark the place where it overlaps and unwrap it. Use a ruler to measure from the start of the ribbon to the black mark. A sheet of paper or dollar bills can also be used if you are in the office.


A great fit is not only about the wrist. Other factors contribute as well, such as case diameter, case thickness, material personality, and other components of the watch. Case diameter is the width of the case. For men, this tends to be between 45-50mm, with women’s watches averaging less than 34mm. Case thickness is the height of the case. Generally, smaller wrists look better with a watch with slimmer case thickness while the opposite is true for wider wrists.  Leather bands tend to look better in slimmer proportions, whereas big face watches pair well with metal bands and larger dimensions.

Additional dimensions

Other things to consider when selecting a watch include as additional hardware dimensions such as the lugs, also known as the legs of the watch due to the functional way they jut out from the case. Lugs can overwhelm a smaller wrist and make it appear to be a poor fit. Crowns and pushers should also be in proportion to the size of the wrist. There are also racing watches, divers watches, and sports watches for men that offer additional functionality and a different look than timepieces for the office.


Watches are a personal treasure that, with the proper care, can last a lifetime. Trends might come and go, but a well-fitted watch will always be in style. Take the time to measure your wrist with either the touch method or the more reliable ribbon method. Once you have determined the circumference of your wrist, take the other desirable facets of your timepiece into consideration. A wearer can use their timepiece for the office or on multiple adventures.

The signs of a quality watch


In an era filled with smartphones, smart watches and Wi-Fi enabled gadgets looking at your wrist to tell time has become virtually obsolete. The quintessential timepiece has now become a luxury. This engineering marvel made up of hundreds of pieces has an astonishing number of variations, styles and brands. Finding a luxury watch may be easy, yet finding one that accurately communicates your passions and is manufactured at the highest quality may not be such an easy task. A well-crafted luxury watch or luxury sports watch should last for many years to come, to be passed down from generation to generation.

What to look for:

  1. The Case: Not all steel is the same

Case of a watch

Resistant and malleable is the name of the game when it comes to luxury watches and luxury sports watches. There are many types of stainless steel that vary in metal compositions. The combination of chromium, iron and nickel from 316L steel sets the benchmark when it comes to stainless steel. Most watches are made from 201 or 304 stainless steel that is much more economical, but 316L steel is much more corrosion and magnetic resistant. Not to mention its strength and luster.


  • The small addition of nickel makes it hypoallergenic
  • With its extra-low carbon content, the 316L steel is seawater corrosion resistant. Perfect for those looking for a luxury diving watch.


  1. The weight: A heavy watch is a good watch.

A heavy watch signifies a quality watch. A quality timepiece is made up of several parts that on their own amount to some weight. The additional parts should be crafted from sustainable materials that together produce a durable watch.


  • Heavier timepieces usually mean they used a higher quality steel
  • Solid, sturdy well-constructed timepieces should be substantial in weight


  1. The Glass: Look for reinforced mineral crystal with sapphire coating

The glass of a timepiece is extremely important and should be taken into consideration. The materials used in timepieces have changes over the years. Mineral crystals will shatter if struck hard enough but will not crack. A Sapphire glass will rarely shatter, they are scratch-resistant and will maintain an impeccable appearance over time. With the mixture, you get the best of both.


  • The higher the quality of the watch the thicker the Sapphire glass
  • Sapphire glass is a sure fire sign of a quality timepiece


  1. The Statement: Communicate who you are.

When you buy a luxury watch or a luxury sports watch a statement is made, without the use of words. The savor of wearing, feeling and owning an item must be felt rather than expressed. In order for this to take place the timepiece must be more than just a “fine item” it must compel your inner most desires. The statement is entirely personal and unique to the wearer. Which for us is the most important attribute when looking for a quality watch.


  • Your timepiece should be passion driven and bold.
  • Make sure who you are is communicated without question

The love for a watch is emotional; the quality is the silver lining. The timepiece located on your wrist is an extension of your personal communication; make sure to buy something that truly expresses that. A timepiece is not only luxurious but a reflection of who you, who you have been, and who you will be.
