    ETA 7751 Moonphase

    If you know your way around a standard 7750 you should not have any trouble at all, there is not a lot more to it.
  2. I can think of be several causes for poor power reserve- Inefficiency in the auto winding mechanism (can be caused by a number of things, e.g. wear, contaminants, and dry lubricant). - Mainspring bridle slipping too early during winding (usually a wear or lubrication issue in the mainspring barrel)- Watch stopping before the mainspring is fully unwound (usually caused by particles/ dirt or a defective / worn part). In this case the full power reserve may have built up in the mainspring as it should, but watch stops when it comes to a lower state of wind.

    ronda number

    Try windingstems.com, you can search by the Ronda number. looks like this one will fit a number of Tissot movements.

    Hampden jewel change?

    I am not familiar with the watch in particular, but I expect the jewels are rubbed in? You need special tools to open and close the jewel setting, they can frequently be found on eBay (people tend to mistake them for pin vices!) Mark made a video about rubbed in jewels https://m.youtube.com/watch?v=A2Z1aosVaqk

    ETA 2824 problem

    Reversers should be replaced, alternatively can be cleaned and then lubricated with Lubeta 105 if they are in good condition.
  7. People are happily bidding on it... you would think anyone looking for one of those would have an understanding of the basic requirements for it to work!
  8. Yes the slipping bridle is attached to the mainspring, and both mainspring and bridle are constrained within the holding washer
  9. Hi Frank, many thanks for this, I have not come across it before. Would you have a Bergeon ref number by any chance?
  10. Thank you clockboy, that is my gut feel too. I do not see much point in the 2A if it can only be used with thin oils. Perhaps I will end up using it with Moebius 914 for pallet / escape lubrication on low beat escapement lubrication.
  11. In the Q&A part of this link from Christian, http://watchguy.co.uk/how-to-repairing-watch-hands/ someone mentions the use of a modified presto tool (in the context of chrono sub dial hands, but I guess could apply to centre chrono hand). This allows pulling on the tube rather than the hand / rivet. I have never tried it myself but it seems to have some merit, some of these hands can be pressed so tight the rivet is the first to give way.
  12. Hi all After years of using traditional oilers, I recently decided to bite the bullet and invest in a set of automatic oilers in the name of efficiency. I am familiar with the use of the oilers 1A and 5, respectively for shock protected jewels, and train wheel pivots. My query is specifically about the oiler ref 2A - « For pallets, mechanical parts, oiling spots difficult to reach » Basically my question is, does it work with grease? At the moment I am thinking of using it to lubricate keyless work and high friction points with grease, but I would not want to fill up the reservoir to find out it is just too thick to work.... any advice/ experience would be appreciated! Many thanks Oli

    feintaster tool .

    I would not hesitate at £85 if in good condition. They sell for much more pre-owned on eBay. Great tool, fantastic to work alongside a Jacot tool
  14. It looks home made, but I am sorry I cannot figure out what one would do with it...
