Just had the battery replaced on my Wenger Swiss Army watch Model : 7987X/T. The red second needle is no longer moving.. its stuck on the 30 min mark. Watch works fine otherwise. Could not find any info on this in the manual. any ideas on how it cna get it to start moving ?

If the second hand of your watch isn't moving, but the watch is otherwise keeping time, you most likely have one of two problems. The simpler to fix problem is that the second hand might have come loose from the post onto which it's been fitted. It's a simple friction fit, and a watch technician would simply remove the watch movement from the case and very (very!) gently push down on the seconds hand to re-seat it. If that's the problem, that's all there is to the repair.

A second potential cause for this behavior could be that a speck of dust or crud has gotten into the gears that operate the seconds hand, preventing it from moving. This can easily happen when changing a battery--many watches tend to get somewhat of a buildup of crud where the watch back meets the case. Especially with screw back cases, the process of loosening the back also loosens the crud layer, making it easy for little bits to fall in. If you do have crud in your movement, you're a bit limited in what you can do. Unlike old-time mechanical movements, very few quartz movements are made to be disassembled and cleaned. Instead, a watch repairer may be able to blow some air (not compressed air from a can--that will probably wreck your movement) to try to clear the gears. If that doesn't work, there is a little device that some watchmakers have that runs your watch at about 50 time as fast as normal. Spinning the gears like that can sometimes generate enough force to clear a blocked gear train. I have done this to resurrect several watches whose hands were stuck. However, I was still able to see the "pulse" of the second hand on those watches, even if the hand itself never moved forward.
