Enicar Jewel Lubrication

[Mitchell511]

Hello, I am a beginner watch repairer working on my first project. It is an Enicar from the late 50's. I am about to begin the reassembly but I am unsure if I need to oil this jewel. I'm not sure the correct name for this jewel and I am wondering if it requires any lubrication. There is a small screw you can remove, but since the jewel has a hole I'm unsure if it needs to be lubricated. Any advice would be appreciated.

Thanks, Mitchell

When you unscrew the screw, there will be a cap stone and a pivot jewel in a setting. They will come apart. You should wash both to clean off any old, gunky oil and put a (small) drop of 9010 on the bottom side of the cap stone and then place the fitting over that and replace both into the location on the bridge and screw back the cover plate. What you want is to end up with a sandwich where the fresh oil is on the bottom of the cap stone and the wheel pivot will go through the hole in the pivot jewel and be lubricated by the oil between the cap stone and the inside of the pivot jewel.

Thank you for the reply, I don't think this is a cap stone jewel and thats why I'm confused. It does come apart, but the jewel is open on both sides and there is no cap to cover it. I believe the center wheel slides through this jewel since it is open. I am somewhat familiar with a cap stone and to my knowledge this is not a cap stone. Thanks again.

I think if the setting is unscrewed and removed there will be 2 jewels there. One in the setting and one in the bridge. Both have holes. 

The jewel in the setting that is screwed on top will be for the 4th wheel (sweep seconds) and the jewel with larger hole in the bridge for the center wheel. Both jewels would be oiled.

The center wheel would have a tube for a pivot and is installed under the bridge in the photo.

Remove the setting to confirm, then clean the jewels well. It would be removed anyway to adequately clean.

Your watch is itching for a bath, no point to reassemble without real good clean.

There are many discussions on cleaning solutions, machines and pegging, available to you through the search function. 

Good luck pal.

Hello, yes that is exactly how it is. After cleaning the jewels should I place oil around the jewel hole or in between the two jewels before putting it back together? Also will 9010 be the appropriate oil here? Thank you so much for the help.

Hello, I should have clarified that that picture was taken during the disassembly so I would know how to put it back together. I appreciate your response, thank you!

If it's the centre wheel, I'd put a tiny amount of D5 or HP1300 on the shoulder of the centre wheel pivot, not on the jewel itself as any excess might flow into the tube of the centre wheel and get onto the centre seconds arbor.

I saw HectorLoois reply as I was writing this reply:) 

My preference in this situation would also be to place oil on the pivot instead of the jewel. 

Those two wheels would normally see different oils. I would apply sparingly, less is more as the trite expression goes so the oils don't wander to the other pivot.

I'm going to defer to people with more experience on the larger center wheel; I always use 9010 on the 4th wheel.

Great, thats what I was thinking since I don't want an excess oil in places it doesn't belong. Thank you I appreciate it!

Ok great thanks! Yes I will apply oil to the pivots instead if the jewel. Thank you for the help!

Sorry @Mitchell511 for the bum steer, that's why it's usually best to ignore me until others have chimed in (and probably why I haven't gotten anything running yet).

Not the same Enicar calibre, but the same principle. Here are some pictures from my Enicar 161 service walkthrough.

It’s a hole jewel. No need to dissemble unless the jewel needs changing. Just lubricate with HP 1300 or D5.

No problem at all! We are all hear to learn, and I appreciate your comment.

Great thank you, and yes it seems to be in good condition still.

Its a cap jewel matey. Pop it off, clean the jewel underneath it, lube it, pop it back on. . Sorry my mistake , i didnt look at the 3 rd picture of the center wheel. Not a cap jewel.
