Your welcome.  I general oiling one movement is the same as oiling other movements, unless it's something special.  Light oil for fast moving parts and heavier oil for slow moving parts. 

thanks again. i have a list that i have used in the past. also been reading info on oil on here to get the latest info..

AS984 / 1002 is a nice basic sub-seconds time only manual wind movement so about as uncomplicated as it gets. You're highly unlikely to find a service manual for it but all you need to do is to follow a logical system of work, work slowly, don't force anything, and take pictures of every step of the strip down as reference for when you put it back together. Also make sure you let down the power before you start, and it's good practice to remove the balance cock and balance and put it somewhere safe at the start of the works, that way it's less likely to be damaged.

One thing to note (and I have just checked this on a 984 in my parts stash) is that both the crown wheel screw and the ratchet wheel screw are reverse (left hand) threaded, so turn clockwise to undo. Otherwise there should be no real surprises.

I have attached a copy of the BHI guide to lubrication which should be more than adequate for your movement and is a good starting point for most clocks and watches in the absence of anything more specific.

If you get stuck on anything just ask on here.

Let me know how you get on! I have (I think) the same movement in a Timor WWW that's next in line on my bench. I think as Marc says, hopefully pretty straighforward. Have you folloed Mark's courses on watchfix.com? I think with the knowledge there, you should be good to go.

I have watched a quite a few of his videos. Also worked on Seiko auto's. Citizen & walthan. Not done any for a year or two. But when I have time. Would like to do more!

      Hermle 340-020 slowing down as days go by

      From the photo the pallet arm looks as if it has been tampered with the edges are not nice and straight this can cause problems on the banking pins.

      Update, I discovered that I could change the mainspring by removing the arbor and sliding it out from between the front and back plates. So I put a new mainspring in. This it what I  get over a 7 day period After winding                                          amplitude is 1 1/2 turns plus a few degrees.                                                                        ie just over 1 1/2 turns. 1 day after winding     gained 1 sec      no amplitude check. 2 days after winding   gained 1 sec      amplitude 1 1/2 turns                                                                                                              i.e. it lost the few extra degrees 3 days afer winding    gained 3 sec     no amplitude check 4 days after winding   gained 5 sec     amplitude 1 1/2 turns                                                                                                               i.e. unchanged 5 days after winding   gained 7 sec     no amplitude check 6 days after winding   gained 16sec    amplitude just over 1 1/4 turns 7 days after winding   gained 24sec   amplitude 1 1/4 turns. From  Based on video inspection, I am getting full pallet lock. So, my data seems to be at odds with the statement "swing of a balance wheel has nothing to do with the rate". However, I have noticed the banking posts are not controlling the lever position on the right side.  I may have some work to do here.

      Crown Snapped Off - Armani Renato Watch

      By RichardHarris123 · Posted

      I can't tell whether or not some stem is stuck in the crown, I  think so though.  If the crown is stainless steel you could try alum to disolve the stem of try drilling it out. If all else fails, buy a new crown.

      Does anyone use the x5 eyepieces,  when i use them on my different amscope , the magnification changes to x5 but the field of view remains exactly the same as the x10, so nothing gained. The optical lenses can't be swapped out or at least they are not available as far as i know.

      I think maybe we're all a bit dim @ManSkirtBrew 🤣 99% of the time I'm working with the 0.5X Barlow, so mags from 3.5X to 22.5X. When I need a close up of a pivot or jewel, I take the Barlow out, and even put in the 2X Barlow, but it's a nuisance. So like you, I had that D'oh moment, why don't I just use 20X eyepieces (WF20X/10). They take seconds to change, and you keep the working distance. The only downsides are lower field of view, and less brightness.
