I got tainted from this forum & tried my hand at my 6309 & had success. That put me on the road to hell & I do it to any watch I own (even quartz watches). It's time consuming & luck, but I'm more than happy with the results. The only ones I've never had to touch were my Eco Drives & the great Sumo. Right out of the box, they have all run spot on.
