very very simple
if it has spring bars as i believe it does you can do it with something as simple as a fine bladed penknife. just slide it carefully between inner lug and strap and twist it down. the blade should catch on the ridged end of bar and it will come out of the hole in lug. to refit do the opposite.
you could spend money on tools to do it, but i've never found the need and never scratched a watch doing it.

Spring-bar tool
Graham,
Fully accepting your preference for using a knife, I can't help but wince slightly at the thought of using one for this purpose. My first concern would be for the risk of drawing blood from one's fingers in the event of a slip - with the consequent risk of bloodying the watch and strap. Having acquired a good spring-bar tool (at very modest cost) I find that it makes the task of changing a strap so much more relaxed and enjoyable; and feeling fully under control, it makes the chances of slipping and damaging either oneself or the watch so much less.
Also, as a small-time knife collector, I'm also thinking of the potential for damage to the blade of a perfectly nice knife!

Mando, your quite right. i've...
in the past and even a royal crown derby butter knife with blunt blade, but
still prefer a thin blade.
mastered the art of not self harming :)
solid end links & notches(speedmaster etc) in the back to access
springbars i use a point like an old blunt dart as none of the tools seem to
fit.
risk of harm is far less.
suggestion of a tool is probably better for a novice like redduc.
