Information

Generally, the outer ring of a Digital sport watch will be engraved with 500/400/350 and other successively decreasing numbers. The physical quantity represented by these numbers is the speed, and the unit is kilometers/hour; and this bezel is also called a speedometer, which generally has this Most of the watches with a similar outer ring are sports watches, which are also the most common calculation scale system in chronographs.

How does the LASIKA Digital sport watch measure the speed?
Take a car driving on the highway as an example. Generally, there is a distance indicator on the highway. When the starting point is passed, the stopwatch is started, and the second hand starts timing at 12 o'clock. When it moves 1 km, it stops timing. The number referred to is the average speed of the previous kilometer. For example, if there is 60 at 12 o'clock, then one kilometer is walked in one minute, so the speed is 60 kilometers per hour.

How to calculate the numbers?
So how is the position corresponding to the LASIKA Digital sport watch bezel number calculated? Actually, it is not difficult, as long as you know where the number 500 is engraved, and then do a simple division: Calculate 1 km at a speed of 500 km/h How much time is needed, in seconds.

1 hour = 3600 seconds, which means that 500 kilometers need 3600 seconds to complete, and 1 kilometer requires 3600 divided by 500 equals 7.2 seconds, so 500 must be engraved at 7.2 seconds on the LASIKA Digital sport watch disk. Other digital scales can be deduced by analogy.
