tachymeter on watches

[denniskee]

hi guys,

i cant figure this out.

i understand / know the rotating bezel on typically diver's watches is like some outdated technology of "stopwatch". :sweatsm::sweatsm:

but how do u use / read the tachymeter thats on the bezel? :dunno::dunno:

those are only ornaments for ppl like us... i mean... u will look beyond the 2 longer hands when u see your watch? btw, which is is 'tachymeter'??? got this thing ar?

oh!! so i must know the distant traveled inoder to use the function?

Yup. It would help a racer determine lap times.

From what I vaguely remember..

In times past before speedometers and GPS, to determine the speed of a sailing ship, drop a float/buoy from a point along the railing and mark the time taken for the float/buoy to reach another point along the ship.. (of course you attach a line to recover the float for reuse..)

Since you can measure the length between the 2 points (and if you always use the same length as reference), you can calc the speed of the vessel.. With the markings on the tachy, you can create a chart with which you only require the elapsed time to find the 'knots'..

Just my say..
