On my Luminox 3051 BO watch, the second hand (showing seconds evolution) does not match exactly with the marks all around the watch. Regards Robert

Pls clarify: Lots going on behind the scenes (in your movement) that is inherent in battery powered movements.

Thanks a lot.

Robert,
Some watches, battery watches, are self correcting. As the second hand goes around the dial the watch is capable of slowing slightly if it determines the watch is running fast. Also the watch has a train of gears that have a tolerance or slop if you will that prevents it from being as accurate as you wish. There are watches that move in 1 second increments(difficult to do what your after) and watches that move a dozen times between markers and "appear" to not even ticking as their movement is so slight and fast (1/12th of second each movement) it looks like they are continuous. Ticking is not correct terminology but I use it to describe the movement of the seconds hand. If you have a Rolex take a look at the seconds hand with a loupe. You may be able to tell it actually does tick, just so fast you can't tell. The lack of precision in the movement is the actual cause of your problem. If you need an accurate time recording watch get a chronograph or watch with a stop watch built in. If you want the most accurate chronograph go digital.
