What do the 3 dials on a Fossil watch mean?
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.
How does a tachymeter on a watch work?
A tachymeter is on the bezel of a watch and can measure speed based on time traveled over a fixed distance. The allows the conversion of elapsed time, in seconds per unit, to speed in units per hour. The tachymeter scale and measure times from approximately 7 seconds to 60 seconds.
What is a tachymeter on a watch?
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.
Can you dive with 10 ATM watch?
Watches with 10 ATM (100 meters/330 feet) are allowed for swimming and snorkeling but not for any diving. Watches with 20 ATM (200 meters/660 feet) are perfect for any water sports activities, such as scuba or skin diving.
How deep can a 10 atm watch go?
100 meters

What is the purpose of a tachymeter on a watch?
What is the purpose of a tachymeter?
The most common use of a tachymeter is for measuring the approximate speed of a vehicle over a known distance. e.g.) Based on how many seconds it takes a vehicle to travel 1km or 1 mile (the available measuring range is up to 60 seconds), the average speed within the distance can be calculated.
How do you use a tachymeter and chronograph?
To use a tachymeter bezel, press the chronograph pusher to start the stopwatch. Once the object (for instance, a car driving one mile) passes the finish line, press the pusher again to stop the stopwatch. Then reference the tachymeter scale marker adjacent to the second hand; this figure tells you the speed of the car.
