Where can I find a schematic for a Hamilton 986A wrist watch?

Removing the stem on a manual wind-up wrist watch can be a delicate task, as it requires some knowledge of watch mechanics. Here are the general steps to remove the stem on a Westclox W3 manual wind-up wrist watch:

1. Make sure that the watch is not wound.
2. Use a small screwdriver to remove the crown from the watch. This is typically done by gently pressing down on the crown and twisting it counterclockwise.
3. Once the crown is removed, you should be able to see the stem.
4. Use a stem removal tool to push the stem out of the movement. A stem removal tool is a specialized tool that is designed to remove stems from watches, it can be found in most watch repair kits.
5. Carefully remove the stem from the movement.
6. Once the stem is removed, you should be able to access the movement of the watch for repairs or maintenance.

If this is a self winding watch then you will have to rotate the pendulum inside it about 200 times before it will start. The directions should show you the proper way to rotate the watch to move the internal mechanism.

Your watch is 12 hours out of step. (The date changes every second revolution of the hour hand.)

Wind your watch forward 12 hours, (you may have to reset the date) and it will then change around midnight.

Make, model, all numbers, please.

mcdevito75 here, In most cases the glass (crystal) come off or out thru the back of the watch which means you"ll have to remove the quartz mechanism, and that means removeing the stem, thse quartz stems are very prone to breaking while being removed form the quatrz mechanism and the cost of a repair may be more expensive then a whole new watch, shop around get a price from a small watch repair shop on repair verses a new Fossil watch.

Even the best watches need servicing time after time. Obviously there is no battery fault, but something related to mechanics or electronics in your watch. Get advice from watch repairer.

Toward the back case.

This happened to mine, couldn't get a spring anywhere. But managed to fix it by using a staple which I cut to size, Works fine now.

Most likely your watch needs to be serviced.

Every watch, both mechanical and quartz needs regular service.

When the oils in the watch dry out they get gummy and will work against the gear train. They also stop lubricating and friction builds up causing wear.

Hope this helps,

i own a tissot too. instead of removing a link, just change which hole the link sits in on the clasp
