  1. I bought this book from book depository last year. Quite happy with it. Good focus on reparing techniques and very good tips on reparing wristwatches. I couldnt get the copy from any other only bookstore and I though that was sold out. Suprinsingly BD had a few for sale.

    Any one used bergeon 8935 ??

    I have a Bergeon 5378. It costed me a fraction of the price of Bergeon 8935. Quite happy with it. If I was considering buying an hand fitting tool nowadays I would probably consider one with derlin tips like the Horotec ones with replaceable tips.

    Ok, if you are only considering ergonomics than its fine!

    My opinion: just check if they are antimagnetic! This is probably one of themost relevant aspects. I have similar ones and they are not antimagnetic and one of them is always magnetized. Searching data from then sent links is not stated that they are antimagnetic.

    Date wheel spring for Certina 25-651

    I have the same problem as mention by Alexndr. The spring is mado out of copper (seems to me). The small dimensions put another question...what to use in order to shape the spring? Did anyone solved this successfully? BR Henrique
  6. Hi Mark, I'm considering to join the program but I would like to know a little bit more about the courses that will be available, in order to select which patron option fits me. Can you please describe course content in detail? One of my concerns is related with watch movement overhaul. I love to watch you presenting Rolex movements strip downs and other top grade movements but, unfortunately I suspect I will never have one in front of me. I started this hobby 2 years ago, and I love in. Being engineer helps, but I have been facing a complete lack of possibility to improve my knowledge about watch repairing. Schools are expensive or don't allow older people, like me, to enroll. I think that your online videos are the only consistent channel regarding information and practice techniques. My best regards, Henrique

    Bem-vindo Rui!
  8. Hi Geo, Yes, that was my first option, but none was available. So, due to that I was even consider to get a new one. Regards, H.
  9. Hi, Some of my projects are stopped due cracked jewels. This means is a motivation to move into jewel setting activities. Recently bought a setting jewel machine. In order to measure the inner jewel diameter, as shown by Mark Lovick on the related video, he uses a calibrated set of jewels inserted on a plate: the Jauge Seitz. Seems to me the best, and the most efficient way to measure the inner diameter. Are they still available on the market? Are there other suggested options? Thanks in advance, Regards, Henrique

    Regulator Pin

    Ok, I sloved it by using the thinnest oiler. The thinnest screwdriver was way to thick.

    First Balance Staff Replacement

    Hi, For 2 of my projects, change the balance staff is mandatory. Currently I'm considering which are the best tools to carry out this job. Buy a Platax tool is not a priority. I have a modest staking set, but I need some extra tools to take this operation smoothly as possible. Bergeon 5483 was a possibility but the price makes me think twice...how about to use some of the assorted stakes and punches that come with the Platax? Does anyone recommend a budget tool to carry out this job? My main concern is the deformation of the balance arms as pointed out by clockboy on a previous post. I think that a compromise between pressure on the staff and correct clamping on the balance arms must be achieved.
