  1. Dear Rollee, I am the creator of this thread, and you are more than welcome to post comments and ask questions regarding this movement any time you want my friend. Yes sir, you can purchase parts from places like CousinsUK, and it's a fun and challenging movement to work on. The best part is that no matter what, you can always get a replacement movement if all else fails :) My hope is that this walkthrough helps you, and gives you the confidence to try and fix it yourself. In Christ Jesus my Lord Lawson
  2. Thank you mlfloyd1 and all the other how have left such kind words. I'm glad this walkthrough has been a blessing to you all, and I hope it continues to inspire and encourage others to take on this movement. In regards to the optics I use, they are made my Zeiss, and are called Eye Mag Pro. They are mostly designed for the medical industry, for neurosurgeons etc.. I created a thread on them here mate: They are not cheap, but I was working in the industry at the time, using them 8hrs a day 5 days a week, and could claim them on my tax return If you can afford them, they are
  3. I have been notified that the links to the PDF's of the 7750 walkthrough have been damaged. I have re-uploaded them to help all those wanting a copy ETA_7750_Service_Walkthrough_-_Assembly.pdf ETA_7750_Service_Walkthrough_-_Disassembly.pdf
  4. Hey Colditz, Thanks for the kind words mate It's comments like these that make the time and effort all worth while. I totally agree with sstakoff, you MUST use the proper movement holder when replacing the hands. Damaging a jewel is a lot of extra work and extra tools/skills to correct it. Better to play it safe and use the holder that supports those jewels. The 7750 is an excellent movement to work on. You're really taking the plunge into watch repair: this being your first movement, but take it slow and gentle, and follow the guide, and it's more than achievable with your ba
  5. Hi Matabog, I don't believe so mate. If that where the case then you would have to VERY carefully mark which one is what as you are disassembling the movement, because they look exactly the same ... and I have never done this. They also do their function at the same time of the day, so there can be no variation in the tooth count. Please guys, if I am wrong let me know, we are all here to learn and I could be mistaken.
  6. The replacement mainspring arrived at last, so it's time to assemble the movement. To install the new Mainspring, keep the coloured side of the keeper up and press gently into the Barrel with Brass Tweezers. Then install the Arbor . Then replace the Barrel Cover. After discussing this movement with a master watchmaker and good friend, he recommended using Jizma Green to lubricate the Arbor. Install the Barrel and Setting Lever Screw. Then replace the Mainspring Bridge. Install the Click Spring. Then the Click. Now
  7. Hey AlexanderB Excellent write up mate, and the pictures are wonderfully clear. I'm very interested in seeing more on the system holding the end-stones of the Balance ... they look very "old school" indeed. Keep up the great work and writes mate!!
  8. The proper way to apply Fix-o-drop is with a Epilane Bottle as pictured below: The lower part of the bottle is filled with Fix-o-drop (to the blue line), and the items you wish to treat with the product go into the white basket. Then you affix he lid and flip the bottle upside down, coating the product on all the parts in the basket. When the parts are remove the Fix-o-drop evaporates rapidly leaving a coating that holds the oils in place. Unfortunately the asking price for these bottles is pretty steep, and I don't own one at present. I just dip a cotton bud in the Fix-o-dr
  9. Just a quick update on the progress of the 620 service. As I am still waiting for the Mainspring to arrive from the UK I took the time to clean the Case and Caseback. The condition of the Case was good, with just the typical dirt and grime between the Lugs and around the Pendant. With a little gentle cleaning the finish on the Case came up rather nicely. So now it's just a waiting game for the part to arrive and assembly to begin
  10. Before we remove the hands and dial from the movement, I wanted to clean the dirt that had built up around the edge of the dial. This has to be done with great caution and a gentle hand. Firstly get a piece of pegwood and a very sharp knife. With the knife, feather the end of the pegwood to create a fine bristled brush, and use that along with some Rodico to remove the dirt. Remember! Always err on the side of caution ... it's better to stop early, use the Rodico to clean away the loosened dirt, and check your progress; then to continue on for too long an
  11. Flopin Flip Flop Watchman! You were right! It WAS a broken Mainspring! Yes Pallet Boy! And this can be the work of only one man! You mean the "Overwinder"? Precisely, Boy Blunder! Approval was given by the owner, and the part has been ordered through CousinsUK ... so it should arrive in Australia in around 10 days.
  12. Omega 620 Complete Service I'm servicing a nice vintage Omega DeVille for a friend at work, and I promised her I'd post a walkthough of the service online so she could see the progress. It's an old 2 hand mechanical, which is rare to find in the DeVille range these days, and it has nice patina on the Dial. Along with the service to the movement, it will need a new leather strap, as the original one has succumb to age. I'm glad that the glass is in good condition, as replicating it would be an endeavour to say the least; and fitting a standard flat glass would take away fr
  13. Hi Alex and welcome to the forum mate In answer to your question: This is just the way I've been taught mate, and your mentor may teach a different way. This is why I like to see people post detailed threads on how they repair and restore movements. Then all the different techniques can displayed, and people can try them out and see which works best for them; or is an improvement on their current procedure. I also agree that adding the balance as the final step is a good way to avoid damaging it. But I often fit it to make sure the work I've done on the train is functioning correc
