  1. I was tempted by this very watch but put off by the fact that a set of new hands wouldn't match the aged lume on the dial. Are you going to relume the new hands or live with the difference? That model will date between 1993 & 1996 as the calibre 1109 was the launch movement in the SMP. The calibre 1120 was introduced in '96 to rectify the supposed issues the 1109 had with automatic winding. The 1120 has 2 extra jewels and a redesigned winding mechanism (unique to Omega I think) that gets the mainspring to fully wound in less rotations. I will be very interested to see your results. Good luck!
  2. After a long break, due to graduating from the British School of Watchmaking and beginning employment as a watchmaker, I have finally found the time to give my website a new look and begin to finish off the remaining blog posts from my time at school. The latest post details the Frédéric Piguet Calibre 1180 and I've also thrown in some history about the once great movement maker, thats name is now defunct, for good measure. http://raulhorology.com/2013/11/frederic-piguet-the-ultra-thin-chronograph-calibre-1180/ I hope it's an enjoyable read and as always, any feedback is appreciated.

  3. Try Northern Clock & Watch in Northern Ireland. Speak to May, they often have a few parts left in stock that others don't. Reasonably priced too. Note- just seen your other thread, glad you are sorted. The above is a good place for anyone trying to source vintage parts though.
  4. The glass isn't glued in on a MKII. It has a seal that holds it in place. Having fitted one to my own MKII I would definitely leave it to a professional! I'm a watchmaker but even I found this a tough glass to fit with the correct tool. To prevent damage to the glass you really need the Omega tool or at least a copy of it. It basically a circular ring that sits perfectly on the chamfered edge of the glass and applies even pressure around the glass. It's a very tight fit and its easy to either crack the glass or lose some of the black paint from the tachymeter scale. Good luck if you decide to have a go but please be very careful!
  5. I mentioned in my post about the ETA 7750 that I would soon be servicing the Longines L688.2, its based on the latter but has been re engineered to include a column wheel based chronograph instead of the usual cam and lever system. I thought I would take the chance to not only write about the Longines and show its assembly but also compare the column wheel and cam/lever chronograph systems. The column wheel system is more common in high end chronograph watches due to the extra costs involved in its manufacture. I hope you enjoy the read and hopefully afterwards you will have a better understanding of the two chronograph mechanisms. http://raulhorology....calibre-l688-2/ Thanks Luke
  6. Yeah, its a shame that quartz watches don't receive the same treatment as mechanicals when it comes to manufacturers keeping stock of parts years down the line. Quartz are seen as disposable unfortunately when things like this and the tuning fork movements should be preserved. They tell the story of a race for supreme accuracy in timekeeping and although generally I have a preference for mechanical watches, quartz has its place. I wouldn't call this beautiful when compared to the 861 in my Speedmaster or any other mechanical movement to be honest but its cool in a retro early electronics kind of way.
  7. Following on from the recent spate of watches containing this movement, here's the story of mine. Thanks to Richie_101 for selling it to me and to keitht for help with some parts. Enjoy the read. http://raulhorology.com/2013/03/the-great-grandad-of-quartz-girard-perregaux-calibre-352-project/ Luke
  8. The moment I have been waiting for since starting the course has finally arrived- learning how to service a mechanical chronograph. We get the chance to service a number of chronograph movements during this stage of the WOSTEP course which allows us to experience the different types of mechanisms used. The purpose is to gain a greater understanding of the most popular chronograph systems and learn how to service them to a high standard. Our first port of call would be the legendary workhorse chronograph, the ETA Valjoux 7750, probably the most popular chronograph in use today and one that is used by a wide spectrum of brands across all areas of the market. A brief history of the 7750 followed by a pictorial assembly and adjustment, plus my relatively inexperienced opinion of it at the link below. I hope its an enjoyable and educational read for you all. Cheers Luke http://raulhorology.com/2013/02/the-legendary-workhorse-chronograph-eta-valjoux-7750-7751-plus-the-longines-l688/
  9. Shellac is definitely still used although the manufacturers use synthetic shellac and watchmakers still use natural shellac. This may be of help to you as well because it explains the process and shows the ideal amount of shellac to use- http://raulhorology.com/2012/08/eta-6498-escapement-fitting-the-pallet-staff-and-jewels-setting-depth-of-lock-and-run-to-banking/
  10. You can polish gold plated watches, etc BUT it depends on the thickness and condition of the plating. The material removed has to take into account the two things above. Your not going to able to remove deep gouges unless the plating is really thick, it's more about brightening it up. I suggest practicing on something that you can throw away if it goes wrong!
  11. I just clean all the screws together and then organise with the parts before assembly. We do have access to technical guides for most movements though. If you need to keep the screws with the parts, clean what you need as you assemble the movement. For example: Clean the main plate, train wheels, train bridge then assemble and cover. Then clean the barrel bridge, etc and assemble. Continue until the movement is complete. Otherwise you will need about 20 baskets! You could organise the screws and take pictures of them, that's the other way.
  12. That's a hairspring degreaser I believe but it may well work. You could also put the parts in small jam jars with the solution and then put the jars in an ultrasonic cleaning tank if you have one. Works pretty well as most modern cleaners have ultrasonic too.
  13. Rocco did mine last year... It was so good, I asked him to do this GP recently... Before... After...
