well owning 6 mechanical watches...
if they are not on my wrist then they are in the winder...
that way when im in the mood for a particular one i just "grab & go" instead of needing to set the time....
winders with programmable TPD (turns per day) and Uni-direction are a definite plus... for my "normal" pieces i set at the recommended 750TPD...for the two chronographs that i own, i set a bit more at 850TPD... i don't know the logic to be honest, but just following some online advice...
I think TPD setting is the bare minimum for any watch winder. I've seen some winders previously with no TPD setting and they just can't provide enough juice to keep the watch going. Becomes even more iffy when you have a few watches sharing one winder slot, and all those watches require different TPDs.
Being able to control TPD will also prevent over-winding, so that's a must-have for me.
Another nice-to-have would be the control of how the watch is wound - frontload the turns all in one sitting, or space it out over regular intervals. The latter is normally preferred as it keeps the mainspring consistently loaded.
I'm guessing that cheaper winders don't have this function (though I could be wrong - not shopped for winders in a long time).
Would probably be worth noting how the winder is programmed to turn before buying.
