I've put some new designs in the store http://www.watchrepairtalk.com/watch-repair-tshirts.html/

pardon the mess

I could not find a single video on how to wind a mainspring back into the barrel after cleaning. I purchased a three set tool and figured it out myself and then made a video for others to learn. Thanks Sent from my iPhone using Tapatalk

Omega screws are a little tricky to find on Cousins but the parts list is here (330 is the base calibre, you can also find the 352 special parts if needed) https://www.cousinsuk.com/PDF/categories/1354_Omega 330.pdf Barrel bridge is screw # 2003, so search for part Ome2003 - not cheap at £7.74, but you may find on ebay etc. Dial screw is 2501 - same price. Gleave lists Omega screws at £4, but don't have these on line - you could call them. To fit to regulator, I believe you have to remove the balance jewel setting by removing the horseshoe clip on the underside of the balance cock.

So this wasn't easy, but Google is our friend... According to the Breitling source pages, this watch has a Breitling cal B62, which from elsewhere appears to be based on the ETA 252.411. The eta site doesn't seem to have the manual, and I can only find the instructions in Spanish, Portugese and Italian, so if you happen to speak one of these then all is good, alternatively you may want to type the relevant section into Google translate... http://guides.mccawcompany.com/downloadable/download/sample/sample_id/61/ It may be the same instruction as 252.511, which can be had in English, but I haven't tried to compare in detail. https://www.cousinsuk.com/PDF/categories/25_ETA252.511.pdf I feel my contribution is done at this point and over to you Good luck!

I managed to get one off a retired watchmaker. It's in perfect condition too It is quiet , efficient and quick!! Sent from my iPhone using Tapatalk

When it happens to me I am just thankful if the lost part is still available for sale!

Well guys, I contacted authorized Rolex Service center that sits 100 Kms from my home town. I decided to go there tomorrow morning and let them check it. I told them about the auto winding not engaging the ratchet wheel. They told they will be able to diagnose and fix it while I am waiting for as little as 100 euros + parts if needed. Unless a complete servicing is required, which I think it's not.

Also a very plausible explanation. Once the hour hammer resets the wheel, the hammer spring (which Mark is shown fitting) is what keeps the tension of the hour counter lock (plastic part) against the hour counter wheel. If this spring tension is off, it would have the result previously described. Too bad they use plastic for this part. I suspect they do so to minimize the wear on the counting wheel itself.

Have a look at this video. At time 2:20, Mark assembles the hour counting wheel mechanism. The way the hour counting works on this watch is that the wheel is attached directly to the mainspring barrel via a clutch mechanism. When you reset to zero, the hour hammer spins the wheel back to zero and the plastic lock engages the edge of the wheel, preventing it from turning - and activating the clutch. I suspect that plastic part is worn. All in, it's a simple repair, but it must be done by someone that knows what they are doing!

Apparently this is know as "hour hand creep", and is a know problem with the 7750 based Omega chronographs This is a explenation from the chronomaddoxx site http://chronomaddox.com/tzof_faq.html#Chrono_Hour_creep

Check the other train wheels for similar errors - being out of true. That movement is not an automatic, correct? If it were, I would also make sure that the mainspring is cleaned and the proper braking grease (8217?) is applied to the barrel wall to prevent irregular slipping, etc.

I'm not an expert on this topic, but I am quite interested in seeing what the crowd has to say. To my eye, it appears like the watch is running ok, albeit a bit slow, for about half the way round the escape wheel - 7 or 8 teeth, on both the entry and exit pallets. But, the second half is a mess. Is it possible that: o The wheel is out of true? o There is dirt, smeared oil or other on some of the teeth? Examine the escape wheel carefully - remove it and check for true or other defects. Clean it and reinstall. I suppose it's also possible that the noise is coming from somewhere other than the escapement. Are you running the chronograph module during the test? Perhaps shut it down. Don't put too much stock in my response - I'm just thinking out loud. Good luck!

Been there many times unfortunately !!!! Non-magnetic parts are the worst !! I use a large loop of Gaffa Tape (which is very sticky) and inspect whats stuck to it with an eyeglass. I have found end jewels, inca springs and even long lost bits using this method. If I have to resort to a vacuum, I cover pipe with a fine cloth (old hanker-chief !) in which I wrap a very strong magnet.

Yes, one of the pinion leaves looks slightly bent. Now, if this is true then here is some speculation: - The auto winder may be broken as a result of extreme force against the winding pinion. - Either the auto winder tried to wind the ratchet wheel which was somehow fixed, or the ratchet wheel wound against the auto winder pinion* * looking at the direction that the pinion leaf is bent, I'm wondering if either the auto winder reverser function failed and it tried to wind the wrong way. Or, when manual winding, the auto winder jammed which meant that the ratchet wheel damaged the pinion while winding.

You could take a pic like this and examine if there is a broken tooth or a defect on the pivot or a problem with the jewel next to the ratchet wheel or...

Not an exact science I have found. I order (if not in my stock) A few sizes up from the actual size. Sometimes just one size up works great & sometimes although it fits it is not tight so I then move up to the next size. Thats my method but probably wrong but it works for me. Crystals tend to increase by 0.1mm increments.

I've already ordered a T Shirt from when I spotted this on your Facebook, Mark, next will be a coffee mug for sure

AKA The Lighthouse Manoeuvre

If you roll a strong flashlight slowly across the floor, sometimes the part will make a shadow and appear larger. I have found missing parts like that. A magnet is also a life-saver. Sometimes I sweep the dust on the floor into a dustpan and run the magnet over the dustpan. Most of the time, though, I'm on my knees either cursing or praying (both techniques work equally as well). Seems my cursing sometimes makes the part mad enough to appear, and if that doesn't work, the praying may buy me a little mercy and the part, feeling sorry for having treating me so harshly, will come crawling back. Whatever your part or whatever your technique, know that you are not alone and all your forum peers are right behind you, cheering you on (with little or no snickering). Shirley

I recently had a part take flight, and my search for half an hour was fruitless, all the time during the search I had my Optivisor on, slightly raised, it was only then, when I took it off, the missing part presented itself on the top of the brow of the Optivisor

You will spend hours sweeping the floor and down on your knees and in some cases you won't find the part. Then one day its there and you will swear and cuss I did I turned the air blue.

If you want to take a wack at it:

Welcome to the Club! Did you try the vacuum approach? - vacuum the carpet then go through the dust bag? Magnet approach? - trail a magnet on a string over the area? Or did you fall on your knees, cursing creation? - that sometimes helps!

Well done Frenchie. I'm a fan of bumper watches, I fully understand what you are saying regarding wearing it, and totally agree with you. Regarding the broken screw, someone before you has probably over tightened it and stretched it beyond its elastic limit.

Great video. Thanks for sharing. I have moved this thread to the Tools section. Sent from my iPhone using Tapatalk
