20 Most Recent Fossil AM3784 Wrist Watch Questions & Answers

Thanks for contacting Fossil.
The only way to know the battery size is to pull out the old one. It might also be in your manual. It might be on the outside of the watch.
If battery is missing, then you will have to measure the cavity and match it against a battery chart.
Best wishes.

mcdevito75 here, Generally, you need only worry about 2 buttons, MODE and SET. ----- Simply press the MODE button ususally on the right side of the dial on the watches caseing, see the display blinking now press set ususlly on the left side on the caseing, press set to adjust the functions, (hour, minute etc.) pressing mode after each function is set. When done press MODE again to see steady display. If by chance there is no MODE button, the MODE button may be a dimple on the caseing you can push in with a pin.

Bands are held to the watch body by springpins. To disengage them, I use a fine blade knife, and pull one end of the pin down by causing the blade to bite into the metal of the pin, between the eye of the band and the watch body. This method will work when dealing with leather straps, perhaps not with a metal band, depending on how much clearance there is between the watch fork and the band's eye.
If there is no clearance, it may be necessary to destroy the springpin to get the band free. Replacement pins can be purchased at a watch repairer.
Replacing batteries: You need the back off. Some screw on, most press in. Press- ins can usually be released with a knife blade, or small leverage device if there is a specific release place on the rear cover. On odd occasions, it becomes necessary to "use a hammer and chisel". Not easy.
Screw- off backs need a tool to engage the slots on the rear. Sometimes can be done with a pair of long- nose pliers.
The backs often have a fine rubber sealing ring, for water resistance.This needs to be put back in place carefully.
The batteries are held in place by various means, spring tension, clamping etc. Sometimes a screw or two must be loosened to free the battery.
Really, it is all a job for the experienced.
I only do work on my own and other family member's watches. I have a range of tools I have made for these. I wouldn't risk doing outsiders' watches. I do bands and batteries, but leave it at that.
