Oiling jewels

[Bonzer]

I've come across a movement (Seiko 6309) that has jewels that don't have oil cups in which to place oil. 

I'm seeking advice on the best way to oil the pivots - is it best to place some oil on the pivots before replacing the bridges or to try to place oil on top of the jewels?

Thank you.

Hi  A touch of oil during assembly should suffice but,  also when assembled you can put a touch of oil on the Pivot head and then lift the wheel up and down to test the end shake and capilliary action will do the rest.

Thanks @watchweasol, I may opt for the latter method as I find the train bridge rarely goes on cleanly and I would end up moving about the oiled pivots while trying to get the bridge on properly and then that oil would be everywhere except in the jewel!

Hi  I too use the latter method as you rightly say the bridges don't always slot on in a oner so there is always the possibility of oil reaching parts it should   not  but both methods are permissable depending on the construction of the watch.

Aren't they the jewel holes for the pallet lever arbor? I'm pretty sure they don't require oiling.

They might well be, but all the other jewels are the same. I just took a photo to demonstrate what the flat jewels looked like.

I see two jewel holes, one with a well the other without.

I think it's just the light. I've taken a (slightly) better photo with flash so you can see the dial side of the mainplate

Fair enough, that is odd. They can't be original to the watch. The only 'flat' stones I know of like that are from pivot gauges like this:

Strange. Perhaps the last repairer only had pivot gauge in stock and they had to raid that to make the repair

Many of the pivot gauges I've bought have missing jewels.

Now that you mention it, I was looking to buy a used gauge on eBay and noticed that most seem to have missing jewels, and despite this fact, the seller is demanding hundreds of dollars.  WT*?   I suppose if one had a drill press. a piece or flat stock of the correct thickness, and a jeweling tool, you would be better off making one.

I don't think you can buy the jewels without oil wells.
