This is placed strategically along that column wheel.  As the chrono is engaged, disengaged, and reset, the grease works itself around the wheel as needed.  It is much better to do it this way than to drench that wheel in grease, but every column face needs to be lubricated. I like doing it this way rather than over-lubricating which can have bad consequences.  In the later photos you'll see that grease has worked itself around the wheel nicely.[ATTACH=full]341398[/ATTACH]Remaining rear assembly photos taken in stages[ATTACH=full]341399[/ATTACH][ATTACH=full]341400[/ATTACH][ATTACH=full]341401[/ATTACH]Here's pic of the pallet for stones after thorough cleaning.  Notice that there is none of the residue as shown in the earlier disassembly photo.[ATTACH=full]341402[/ATTACH]After the rear of the watch was assembled, it was put on the timegrapher and initial readings were taken.  The watch was keeping good time, but the amplitude readings really weren't where I'd like them to be (sorry, no pics).  Seiko states that the minimum amplitude is 180 degrees.  It is well known that most Seiko movements are designed to run at a lower amplitude than their Swiss counterparts.  This isn't a bad thing, it is by design.  While I was getting readings within spec, they were too low for my taste.  Something, somewhere, was stealing power from this watch.</blockquote>
