Resistance turning the crown after storing for 6 months

[A.Sharp]

Hey guys,

Sure 'resistance while turning the crown' threads have been done ad nauseam, but wanted to get feedback on my specific experience.

Decided to break out my M serial DJ from safe keeping today. It's been about 6 months since I have touched it.

Noticed right away that, while when the crown is pulled out as to set the date or time it turns smoothly, the crown has a sort of grinding resistance when turning it in the first unscrewed position (which turning it clock wise many times is the first thing I do before setting the time and date on a watch that has been stagnant).

You really only feel the drag when you turn it slowly, but its very perceptible.

Is there water in my watch that is corroding the inside? or has the lubricant gone dry?

I know its due for a service, but honestly its been running fine and had no problems before this so I figured if it aint broke why fix it (especially since I have sometimes had more trouble than good with RSC).

Before storing it for the past 6 months, it turned like butter.

Any thoughts?
