I am new to this forum so forgive if I make errors. I have for many years repaired and serviced clocks and have now moved on to watches and I am bait confused about the lubrication of Eta Sliding & winding pinions on Eta watches. The Eta tech sheet shows D5 but I noticed that Mark (watch repair channel) uses grease. I presume it is Marks preference & I must admit is is mine too but I wondered if anyone has thoughts on this .

A lot of service sheets recommend D5. I prefer the grease as it usually stays where you put it and you get a better silky smooth action.

I have experimented with several kinds of grease for the keyless work and 9501 came out on top for me but also silicon grease is also very good.

      Hi Nev . No i didn't try this balance in the movement as it didn't run and the deformed staff broke when i removed the roller. Problem is what i think is the correct staff for this movement, the hub seat, roller and collet profiles are all too small for those parts of the assembly. The movement listed on Ranfft's site is correct my movement and the nos staffs i have match the ronda measurements. I can only assume that the wheel , roller and collet openings have all been broached to make them fit an oversized staff, both staff pivots had also been modified.

      B-Dip residue?

      Yes, threw it on the demagnetizer before I cleaned it to be sure.  This picture doesn't show it well, but I can definitely see liquid where the turns meet up.

      My newest 404 candidate, a late '60's / early '70's Waltham with a UTC 33 / Seiko 6601 17 jewel automatic movement. It needed a new crystal and I put on a strap from my Strap Graveyard. The timegrapher was a snow storm before servicing but it cleaned up nicely. I really like the funky font used for the hour markers.

      Hi Rich, the main problem with the balance is if the roller is from this movement. Did Yoy try if the balance interacted correctly with the lever? You can use suitable (by size) balance/hairspring couple from You pile of balances, but the roller must be for this lever (original for the calibre). Not that making roller is impossible, but it is easier to have one.

      Its ok blueharp the pictures you provided earlier of the 3 keyless components,  the setting lever, the setting lever spring and the yoke plus the brass cover plate should be enough. If they are not listed anywhere then you are relying on any lettering on the movement or someone that just knows the movement from experience.
