<!-- from fixya rte -->How to get the timer to stop? - Michele Watches

There is single manual for all adidas watches. You can find procedure for your watch.

ADIDAS-ORIGINALS-TIMEPIECES_CARE-MANUALS_EN.pdf (adidaswatches.com)

What looks like the second hand is the timer hand and starts when you push the top right hand button, you can download the manual for the watch off of the swisseagle website.
The bottom right will stop it so you can record a time and then when you push it again it will jump on to where the timer is still running to show the current lap time, but if you push the top right button a second time after initially starting the timer it will just stop the timer and then pushing the bottom right button will reset the timer to 12.
Hope this helps.

If having gone through this procedure and the timer does not work. Perhaps your watch is faulty and should be returned for repair.

To set the timer hand on these models of Pulsar watches, do the following: 
Looking at the face of the watch, there are two buttons and a crown on the right side. The TOP button is Button "A". - The BOTTOM button is Button "B".
There are 3 positions on the crown: IN (#1), FIRST CLICK (#2) & SECOND CLICK (#3).
First, pull the crown out to the second 'click' position (#3) ... This is all the way out. (STOP THERE! Pulling harder will harm your watch! Don't try to pull past position #3!)
Push and hold Button "A" for two (2) seconds. The dial will sweep around to the 12 O'clock position. You can advance the timer while the crown is in position #3 (second click out) to reset it back to the default position. 
The manual says that if you pull the crown out to position #3 while the timer is measuring, the hand will reset back to the 12 o'clock position... I haven't tried that, so I can't confirm.

I just bought a Sportline 241 last week. The instructions are as follows. Note that there are no instructions for setting the 12/24 hour time option. Mine is in 24 hour mode (which is what I wanted), but I do not recall if it arrived that way or if I stumbled onto this mode when setting the time/date or alarm functions.

I hope this helps.
