What is the accuracy of my Luminox watch?

Quartz movement:

The typical tolerance of a quartz movement has got variations of between -05. and +0.7 seconds per day. External influences like shocks or sudden change of temperature may affect the precision of quartz movements.

Mechanical movement:

The accuracy of the watch depends on the movement and on the individual habits of the wearer and can therefore vary. The average precision tolerances are between -10/+40 seconds per day.
