Thanks for that, fronzelneekburm! Yes, you're quite correct!..
For future reference for "newbies" like me puzzling over the same problem, I noticed that the caseback slightly overhangs the case between two of the lugs, so that provides a handy "lip" with which to lever off the caseback. However you have to remove bracelet springbar in between the lugs to get at the lip - and that proved to be impossible on my watch until I squirted the springbar with WD40 and let it soak in for 15 minutes! (I had similar problems removing braclet link pins when I first bought the watch.) Once the springbar was off, the caseback prized off fairly easily...
The battery clamp was a little tricky to remove - you have prize one end of up and away from the battery.
