  1. Worked great thank you so much! Sent from my iPad using Tapatalk
  2. Hello I need to replace the needle on this oiler. Could anyone instruct on how to do this? The original instructions I received only instruct how to add oil. I think the needle is friction fit but I am not certain and would rather ask then break something. Thank you for the help! F Sent from my iPhone using Tapatalk
  3. Hello! Welcome! I am also in Santa Cruz nice to see someone else on here is around my area Sent from my iPad using Tapatalk
  4. 20 is not much compared to some of the USA supply houses... I mostly use CousinsUK, Eternal tool (great screwdriver, and sharpener prices) then have what I need imported to the USA with expedited shipping for much much less. If it is about the same price I order locally from Kasker(great for mainsprings), and Esslinger. Sometimes I get lucky and find some tools on Micromark. I remember saving almost $150 purchasing my DE-415A demagnetizer from Micromark instead of ofrei. There is also the second hand tool shops. Uncle Larry Watch shop, and Dave's tool and watch shop. And finally I most often use eBay for vintage tools that are quite costly new. Hope that helps. Sent from my iPhone using Tapatalk
  5. I love the US based vendors like ofrei, and esslinger but do shop around. It has been cheaper for me to order from abroad and have it expedited to the USA. Usually it saves me anywhere from $100-200. Which makes me think our supply houses here are quite inflated with pricing. Eternaltools.com has some horotec screwdrivers. And they are a wonderful vendor. https://www.eternaltools.com/watchmakers-screwdrivers/horotec-9-watchmakers-screwdrivers-set Sent from my iPhone using Tapatalk
  6. Fascinating! Thank you! Anyone else own one of these Rowena watches? Sent from my iPhone using Tapatalk
  7. Greetings, I just purchased a NOS roventa pocket watch. It comes with a ETA 6497 movement and for the price it was a great deal. So, has anybody heard of this watch brand I understand they basically case a ETA movement but I cant really find any info on them. I wonder if this company basically became Roventa-Henex SA. Any info would be great as this one is a fairly new one to me.
  8. It is a no. 5 presto tweezer. See attached: Sent from my iPhone using Tapatalk
  9. The lever in the 12 position is used to make the watch run faster or slower. The one at 10 is used to change the resting position of the hairspring and thus changing/managing the beat error. It makes sense that when you moved the lever in the 10 position it dragged the other as it would want to keep the relationship between them the same and therefore independent of each other. When you changed the lever at 10 you might have increased any beat error the watch might have. If it is gaining time and it has not been serviced in a while sounds to me like this watch should be serviced. Sent from my iPad using Tapatalk
  10. Surgical eye loupes are great if you can get use to the working distance and low magnification they don't usually have a zoom feature. I personally use a B&L stereo microscope. I use a 8x loupe occasionally like 10% of the time, but I much prefer my stereoscope which i can use at anything between 3x and 75x magnification all while not having my face directly in the movement.

  11. There are quite a few models of these all similar with slight differences. Usually the model on these is found near and under the balance wheel. I would really just take it out to a watchmaker and have them overhaul it. I own one of these in a pocket watch case they are quite fabulous movements and they keep good time. This is the one I own: Sent from my iPad using Tapatalk
  12. Well it seems I might have figured out what was going on with this. Firstly I took a closer look at the jewels on the balance cock and on the plate. The plate was fine the balance cock was just ever so slightly out of alignment. Once that was fixed the balance started rotating much better. After running some tests I began to notice a small tick sound which I discovered to be the balance ever so slightly rubbing on the pallet fork plate. So I fixed the balance arms so they where no longer rubbing on the plate. Re seating the roller jewel proved to be a very tedious task that I have not yet accomplished. I am awaiting a special tweezer that I hope will allow me to install the roller jewel with more precision. Will update next week. Sent from my iPad using Tapatalk
  13. Yea. Physical books just take up too much space for me, but it seems with this special book I will have no other choice. Will take a closer look at the guard pin this weekend after I fix the roller jewel. There have been a great many issues I have had with this little movement trying to use the best condition gears, jewels, etc. it has been hectic. With this process I discovered that the movements are not even 90% identical the gears and jewels all have various sizes that can be dramatically different from one another. but it has been a good learning experience. Will follow up with my findings this weekend. I kinda need a break for a couple days. It has been a tiring two weeks. I swear I even dream about the possibilities of why it is not ticking... hopefully fresh eyes will do some good. Sent from my iPhone using Tapatalk
  14. The impulse jewel was loose but don't think that will solve this. Will fix that as soon as I can get my hands on a roller remover to properly fix it. The balance moves nicely till it comes in contact with the pallet fork perhaps the guard pin is causing some sort of friction? Too high too low? Don't know will have to examine somehow.. if the guard pin is too high do I just move the roller table up on the balance staff? Been working on this one for the last two weeks now for about 5 hours a day before I decided to ask for help, but it is kinda driving me crazy now. I have a copy of De Carle's Practical Watch Repairing and the John Tope's Watch Repairing course. I need to get myself a copy of Fried's book I just wish it was available in digital form. I highly dislike having physical books.. Thanks for the help! Sent from my iPhone using Tapatalk
  15. Greetings to you all. I have been restoring my Hamilton 912 pocket watch using some part movements. I have replaced all the jewels, installed new mainspring and installed a new hairspring. I have been having trouble getting the watch to start. The mainspring is pushing power through the entire train with the pallet fork removed, but for some reason it is not starting the balance. Any ideas? Sent from my iPad using Tapatalk
