JuiceMaker Posted December 27, 2007 Report Share Posted December 27, 2007 I've always wondered how to use the Tachymeter on the bezel of watch... can anyone explain it??? Link to comment Share on other sites More sharing options...
freddy333 Posted December 27, 2007 Report Share Posted December 27, 2007 Yes. Tachymeter bezels can be used to measure the rate of speed of an object for a set distance. For example, suppose you wanted to measure the average speed a car was traveling. You start the chronograph function when the car passes the starting line and, then, stop it after the car travels exactly one mile. If you note that the chronograph hand stopped at the 4 o'clock position (i.e. 20 seconds have elapsed), you would look at the tachymeter number adjacent to the 4, which is 180. This means that the average speed of the car would be 180 MPH. Link to comment Share on other sites More sharing options...
JuiceMaker Posted December 28, 2007 Author Report Share Posted December 28, 2007 thanks freddy... so ALL these Tachymeters on wrist-watchs are for miles/hour... what happens if the person is in countries that uses kilometres/hour??? I'm in Australia, & we don't use miles, we use kilometres... it'll be confusing to convert into km/hr from miles/hr. Link to comment Share on other sites More sharing options...

Pugwash Posted December 28, 2007 Report Share Posted December 28, 2007 In case you weren't joking, it's UNITS per hour, not miles. If you do 1 kilometer in 20 seconds, you're doing 180kmh, obviously. (Actually, not that obvious to even the smartest TAG Heuer designers. But that's another story) Link to comment Share on other sites More sharing options...

Corgi Posted December 29, 2007 Report Share Posted December 29, 2007 If you want to do unit conversions, you'll have to strap a Navitimer onto your other wrist! Link to comment Share on other sites More sharing options...
