Need to reset the tachymeter on my Guess Steel watch . The dial resets it's self to the "7" location instead of "12" on my watch. Is there a way to recalibrate the watch?

Hi John
this model does not have a tachymeter only day date function on sub dials. there is a similar model 10962j which uses the same case this has the tacho function.

A Tachymeter helps you estimate the speed you are going.

It uses the basic formula that speed = Distance/time

Here is how to use it: (For the full article see the link below)

To use tachymeter, simply start the chronograph or stopwatch when the object measured passing the starting line. When the object reaches the next mile or kilometer marker, stop the chronograph or stopwatch. The point on the tachymeter scale that adjacent to the second hand of the watch indicating the speed (in miles per hour or kilometers per hour) of object traveling between the two points.

For example, we want to measure the average speed of a vehicle is moving. Start the chronometer or stopwatch function when the car passes the starting line, and stop the timer after the vehicle traveled exactly 1 mile or 1 kilometer. Then look at where the chronometer hand (the second hand of the watch) is pointing to, and get the reading or value of the corresponding number at the tachymeter bezel or dial. Let's say the stopwatch stop at 3 o'clock position, meaning 15 seconds had elapsed for the car to travel 1 mile or 1 kilometer. At 3 o'clock position, the tachymetre value shows that number of 240, which means the average speed of the vehicle was 240 mph or km/h.

Your problem is caused by the fact that the watch is 12 hours out of step.

Wind your watch forward 12 hours, reset the date if you need to and you watch will then change around midnight.

(if you need to change the date more than one day, when it has past the change time, wind it back and then forward to step the date forward. You may have to experiment to see how far past the change point (in both directions).

you should pull the big button fully out, then by pushing the tachymeter play/pause you can set the starting point
wish it's helpful for someone :)

It isn't a fault and can be adjusted. Follow this link and find out how to.... http://www.invictawatch.com/ Point at COLLECTIONS and click on INSTRUCTION MANUAL. If you don't know which one of movement makes you have, try both (RONDA first, then MIYOTA). When sorted with type of movement, check how to reset chronograph to 0 (zero).
Rate me, please.

The procedure for the Classima Chronograph watch is different. You need to pull the dial all the way out, press on both buttons and hold for 5 sec, until the seconds dial makes a full cirlce (signalling that the chronograph is now ready for manual reset, then press the button on 2 o'clock until the seconds dial reaches the 12 o'clock position, then press button at 4 o'clock, to transfer control to the 1/10 dial, press button at 2 o'clock again a number of times until it resets to 0, then press 2 o'clock dial again to transfer control to the little hours dial, and press 4 o'clock button number of times until you reset this one to 0 too. Now just push back the dial crown to original position to close the operation. Viola

The trick is to pull out the stem 2 times and use the plugers to adjust each of the dials. Some watches have 3 dials and you have to pull out the crown 1 time or click and use the plungers or buttons to adjust the other dials.

wen u twist th big thing do it twice and press the top button to set dates

On most watches all you have to do is pull the crown to position 2 (the last) and depress pusher A (on the top). The second hand should advance in 1 second intervals. Keep pushing the A pusher until the second hand lines up with 12 hour marker. Push the crown back in and your done!
