I have an Invicta 5103 mechanical wind chrono and the large second hand will not zero out on the 12

My very brief research shows that the Invicta 1805 watch is driven by a Japanese quartz movement. That would certainly explain why you're having trouble winding it.

The easiest check for quartz vs. mechanical is to observe the second hand. If it pulses only one time per second--i.e., jumps one second at a time--then you're looking at a quartz movement (I'm ignore the rare and expensive mechanical jump movements). If it looks like the hand takes 4 or more little jumps to get from one second to another, you have a mechanical movement.

Press mode button until only digital seconds are displaying.
Hold both chrono buttons until you see the word sync on display
Press each chrono button until hour and minute hand is at 12:00
Press mode button

Yes that's common, most chronograph watch's a small subdial is the times second hand. The large second hand is only for the timing function of the chronograph.

Easier than you think.Pull your Crown out to the FIRST stop (were you would normally set your date). Push the "A" button (top chrono button) for your dial at the "3 oclock" area, Push the "B" button(bottom chron button) for the second hand.

• Undo & pull the crown all the way out,then
• undo the adjuster button (the one underneath the crown)
• push the stop/start adjust button one push at a time and it will move in slight increments,keep going till you get the second hand on the 12 mark
• then push the top adjuster and it will go back to the 12 mark.
• Push the crown in and wind your adjusting buttons up and you have finished

Try the following, which I discovered by accident on my Tag Professional. Pull the crown out to the first position, and then you may find that successive pushes of the upper pushbutton will move one of the chrono hands by one division, and the lower pushbutton will move a different chrono hand. Similarly if you pull the crown out to the second position, the pushbuttons will control the other chrono hands. In this way you can set each of the chrono hands to their zero positions. Hope this works for you. Geoff

pull out the crown to either the 1st or 2nd position and use the top and bottom buttons to zero out. please rate my solution

Did you recently have a battery changed. A lot of times on chronos when the battery is changed the battery has to be short circuited to the AC. Which is done by taking tweezers. & touching the positive part of the battery to the part of the watch marked AC. Then try to pull the crown all the way out to time setting position press the top rt button & the second should move keep moving until it lines up with zero. If you haven't had the battery changed try what I told you to do with the crown & the top right button.

Pull out the crown to the #2 position then push the start /stop button to move the second hand up to zero
