Nice collection.

Just an update. The repair I did with the jewel seems to have worked. It had been on test since Saturday morning and was taken off Tuesday morning. The jewel is still holding great. I have returned it to the customer giving the customer my reservations. If the jewel does fail I now have a spare bridge. The clip that was missing I purchased from cousins although a few thou under the original spec it is working fine. WHAT FUN !!! ON TEST IMG_0119.mp4

With experience you'll do it by feel. One thing not mentioned above is where you dip the oiler makes a difference. Dipping at the edge (shallow area) will pick up less oil and in the middle (deep) will pick up more. In the same vein, an oiler held vertically will pick up less oil than one held at an angle. Oilers need to be very clean as an oily oiler wil allow the oil to creep upwards. A poke into rodico each time may seem wasteful but I find that it helps in only getting the desired amount on the oiler. The reason most peope overoil is that they cannot see the oil. What you need to do is ensure that you have a drop of oil on the oiler before you touch the oilsink and make sure that you're accurate enough and the oil drop dissapears off the oiler. If you look at the oil sink you will see some reflection as the oil goes around the pivot but after a while you will learn to trust your actions. If you want to check on your oiling go ahead and oil and then remove the bridge to observe the underside of the jewel. You will see a small drop of oil around the pivot hole but not touching the edges, probably about a third of the available area. Good luck! Anilv

I received a lys Longines 5L for cleaning. Upon opening the case, I saw some surprises under the balance bridge. I have outlined my steps on how I uncoil a tangled hairspring in hopes that others can benefit by this method. George Corder IMG_0505.m4v

I do not recommend these. I noticed small particles in the oil, and on closer inspection I saw that it comes from the hinges. When opening and closing, the hinges grind away paint and material that ends up in the oil. But it is much nicer to use this kind of oil cups than the cheap plastic ones, so there is no going back now. I will invest in the original Bergeon version

Bought mine from cousinsuk . Works okay. And is a little cheaper on cousinsuk . Have tested the Bergeon so have nothing to compare with. Have a small red Bregeon with agate and that works fine.
