Hi there, 

Forgive me if this is not the correct forum for this question.  I have an old Majestime pocket watch that seems to have wheel jewels that are capped. I can't see the staff pivots through the top of the jewels. Is it possible that these jewels are not to be lubricated? 

I looked at the jewels through a microscope and cannot see any dried oil inside them. I wonder how to clean these types of jewels as well.

What do you think?

Welcome to the forum,enjoy. Lubrication is always an interesting debate amongst horologists. Personally you cannot go far wrong by using the range of MOEBIUS SYNT-HP lubricants.. If you go to Cousins Uk web site you will find all of the range variations explained. 
 

PS only purchase small quantities.

Thanks, Clockboy!

I will check out Cousin's website. 

My question might have been a bit vague. I can't see a way of extracting the caps from these jewels to expose the oil wells. I think the caps are staked down, and I think the only way I have to remove the caps is to use a jewling tool and remove the jewels from the main plate. It seems a bit much for a simple case of servicing the movement. The only way I have to lubricate them is to apply the oil through the pivot hole.  A small amount of debris is present in some of the jewel holes. Will an ultrasonic cleaner work to remove this gunk? Has anyone come across a movement like this?

Hi and welcome to the forum.   If the jewels are staled in it’s probably best left alone as trying to remove them may cause damage.  Out the plates through the U/s and re check , might take a couple of passes and then peg out the holes and re clean.

The idea of the little cutouts is that cleaning solution can get in and out. We've all seen jewels though that just won't come clean without a little help from pegwood, including cap jewels. I've had to disassemble these types of settings to get them properly clean, with a jeweling tool.

      Web sites are cheap. Message board are easy. Hosting both is less than 100 usd a year and small advertising would cover most of that.  In the discord group we did some 15 min poc and threw up a couple of different message boards on a domain i host.   The real value is the data / information / hive mind While I'm a rank amateur in watch repair the information and assistance on this board is invaluable. The members on here are friendly, entertaining and a wealth of knowledge This is what needs to be preserved  --Jeff

      HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....

      yes the advertising revenue should generate money. The question is how much money? Then as far as the cost of the website goes that's relatively easy to determine? all you would have to do to grasp costs and profitability would be to go to the link below and you can actually get a website for free try it out for free I believe you get no advertising initially. They also talk about that they'll help you out they have marketing tools and some sort of paid subscription or something. So I guess were shopping for a whatever just ask them what would a maybe could use this one as an example in other words it's going to look basically identical to this is going to have advertising a paid subscriptions what's it going to cost? After all they want to sell or give us a message board like this they should bill answer the questions as they're the people who did the software for this. Yes they really said you can have a free discussion group at least to start. https://invisioncommunity.com/ I was curious about the monthly supporter thing where exactly do we find that on this message board? A quick search I'm not finding it so obviously I'm not looking in the right place?
