How do I remove the back from a Casio Sea Pathfinder SPF-40?

The strap must first be removed. Each side strap is fastened in place by a broad pin which has a slotted fixed head at one end and a female thread at the other, into which a similar head screw is fastened. use a small screwdriver to unscrew the two components. Getting at the batteries is easy but there are four of them, at £5 each!

Richard,
Remove the band by depressing the spring loaded barrels located in watch/wristband attachment.
Remove the 4 screws,remove the stainless cover gently so as to not damage the seal,remove the white plastic cover.
You now have to un-clip the battery restraints using a safty pin.(be carefull).Replace the batteries and re-assemble the same way you dissassembled,use vasoline(pertrolium) jelly to hold seal in plece when putting the stainless cover back on.Do not over tighten the screws.
