If you do not regularly wear yourautomatic watch, we recommend either winding the mainspring manually using the crown unscrewed or in neutral position (minimum 40 times and 100 times for the V4) or purchasing an automatic watch winder. This will ensure that the lubricating oil in the movement remains fluid. As with every micro-mechanism that operates continuously, an automatic watch movement requires regular maintenance.
Do not leave an old inoperative battery in your quartz watch. If it has stopped or the EOL* system is activated, contact your TAG Heuer Official Service Centre.
*Certain models are equipped with an End Of Life system (EOL) to notify you that the battery is nearly flat. The second hand starts making four-second jumps but your watch continues to display the exact time until the battery is exhausted.
