Enicar Jewel Lubrication


Recommended Posts

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!

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.

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.

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).

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

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

Wow this is great! Thank you so much for sharing, this is really helpful 👍

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

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.

    • Welcome to the group Stirky. You can search for just about every subject in the craft here. Don't be afraid to ask if you can't find the answer that may have already been covered ( some ad nauseum LOL ). You don't have to buy Bergeon to get good quality. There are many decent mid-range tools available that will last you a lifetime. Cousins would be a good place to start . Cheers from across the pond ! Randy
    • I picked up a similar amount of these jewels some years ago in a watch and clock fair. Every now and then they come in handy. This week I've got a rubbed in bombe jewel in the balance cock that is cracked and needs replacing. Very handy to have a vintage assortment of these type of jewels!
    • Great diagram with the teeth and pinion count. Simple way to reduce the speed of the hour wheel by the 12:1 minute wheel. Genius and yet so simple. Always good to reinforce the principal by what you have done in your drawing. Keep doing that. I had a drawing on my wall for years showing me this which is very similar to the drawing you have done. Here's a formula to work out the beats per hour of a watch movement. The movement's BPH is dictated by the wheel teeth and pinion count and the hairspring being vibrated to the correct BPH by finding the pinning up point on the hairspring using a vibrating tool.  The reason in the formula there is X2 on the top line is because there are two pallet stones.
    • So I just wanted to say "thank you" again.  The angle is the key bit it seems and yes, it did basically just fall, or float, back into position when I got it lined up just right. I had meant to add that now that I see how it goes in, I totally see how it came out in the first place, and that whomever cloned the original movement didn't pay much attention to the fine details around the setting or how it interfaces with the balance cock or the "rings" on the regulator and/or stud carrier arms.
