Thanks Jocke...now I can see there never was an "LL"
It was a symbol like | | which must be hierogyphics for one division.

When I was looking for a reference based on your earlier picture I found a story about the new tool allowing adjustment with the balance staff while installed. The article mentioned the risk of breakage for the DIY'ers in the world...http://www.minus4plus6.com/regulation.htm

Really like playing the old board game Operation but without the buzzer to warn you of shaky hand

Thanks for sharing. Not for the faint hearted.

Can someone confirm for me DEFINITIVELY whether the Microstella screws in my 3085 (mid-80s GMT-Master II) are right-threaded or left-threaded ('backward", like some gas fittings). PLEASE do not couch any answer in terms of "turn clockwise to advance"; that confuses me already. The reason I ask is because in every picture I see Microstella screws look right-handed, and mine act right-handed (but gosh it's fiddly, so hard to be certain) but all the instructions suggest that the "new" (inside) screws were "clockwise to advance" to stay consistent with the old (outside) screws, which implies they are left-handed. eg the instructions on my (non-Rolex) Microstella tool say "The old Calibres .. had screws fitted on the outside ... clockwise ... inwards ... forwards. The same result is achieved with the new calibres such as the 3035, 3135, 2130 etc, which have screws fitted on the inside; by turning clockwise, the screw is loosened and moves inwards: the watch moves forward." One explanation would be if they thought better of that goofiness by 3085 but does anyone know DEFINITIVELY. Thanks wp.

Thanks for sharing the information.

Thanks Jocke. Very informative. I didn't expect that such a small turn would have such a big impact.

Excellent work as usual, Jocke.

All Microstella screws/nuts are right hand thread regardless if mounted inside or outside of the balance wheel.

I think what is confusing you is the way you are looking at the Microstellas when they are on the inside of the balance wheel look at them with the head facing you.

If on the inside of the balance wheel turning it counterclockwise will move the screw/nut closer to the center ( away from the rim) and increase the rate, turning clockwise will move the head closer to the rim of the balance wheel slowing the rate.

Hope this helps
Cheers.

Jocke you help keep this web site special. Thank You as always.

Looking forward to a Basel Road Trip Report if you are to do one this year..

[JohnFM]

Thank you Jocke -- interesting and informative, as always!

[Jocke]

Thank you all for the kind words.

To wportre: The thread on the adjusting screws are a normal right thread.

[LordNinja]

"At the backside there is graduation which means 1 second per day for each line."

Jocke, doesn't the graduation index depend on which nut is being turned ? [smaller or large 1 or 2 sec / day].

Not to be knit picky but figured I'd mention that. Granted, the attached diagram does set the article straight.

For those thinking of trying to use this themselves take a look at how I did it complete with pictures and training up to it (Including a mistake that damaged my watch!): https://www.rolexforums.com/showthread.php?t=203260
