Yes. First you need to get the address of the (max 4 bytes large) value 
you want to watch:

p @<expression>

Next, add a watchpoint:

watch plongint(0x<address from previous command>)^

If you use the expression directly, you get all sorts of trouble when 
some part of it goes out of scope. Use "awatch" instead of "watch" if 
you also want to break on reads.
