I apologize, but an error has slipped into the assembly sequence of pictures. For detailed info please see the following post: https://www.watchrepairtalk.com/topic/12634-eta-calibre-2472-service-walkthrough/?tab=comments#comment-115897 When I first started out trying to service and repair watches I took a picture of every step, and I really needed those pictures as I didn’t have the knowledge to deduct where the parts should go, how they worked, and how they interacted. Now that I’ve gained some experience, I no longer need all those pictures, but I still need some pictures. For example, it’s very convenient to have pictures of the train of wheels or certain parts of a date complication, and so on. Anyway, I really enjoy taking these pictures as I go and I organize them and keep them on my OneDrive for future use. For this project, servicing my brother’s Atira Plana housing an ETA 2472, I felt it would be fun, interesting and perhaps even useful not only to take the pictures but to edit the pictures adding visual and textual instructions. These pictures are made for my personal use and are not intended as a tutorial or to tell other people how to service an ETA 2472. The pictures simply document how I went about it. Nevertheless, I guess others may find my work useful so I’m happy to share it. There are many ways to service a watch and I’m still learning. That said, I do follow the practices taught on watchrepairlessons.com and they work very well for me! Here are links to my other service walkthroughs here on WRT: Unitas Calibre 6325 Service Walkthrough ETA cal. 2824-2 (17 jewels) disassembly/assembly Vostok 2409 Service Walkthrough ETA Calibre 2472 Disassembly (132 pictures) ETA Calibre 2472 Assembly (131 pictures)

A regular service should do. BTW, we have a section were it's considere polite to introduce oneself, and please don't unnecessarily hook into existing project topics just because you have a same watch.

I have couple of several 2783 movements, if you couldn, t find just the endstone, I salvage one of em. I am sure you wont get stuck, high and dry.

I have sent a message to my Watchmaker.

The embedded picture is actually a link. If you click on it it takes you to the web page which is much easier to read. Check the left hand "Base Caliber" column for 2776. Move across to the third "Caliber Derivatives" column and it lists all of the derived ETA calibers that use the same part. Then move across the columns to the right for the individual part numbers for the bloc, chaton, pivot jewel, cap jewel, and spring, for both upper and lower settings. Order the parts you need by Inca part number. Check out http://cgi.julesborel.com/cgi-bin/matcgi2?ref=X\ZDXITL and you will find a whole load of other calibers that use the same part.

Thanks I will but I'm afraid this is the second time I've made this kind of mistake. Can we change it to: "a mistake you do only twice"?

Cheer up, a mistake you do only once There is a very small probability that it sits / lays in the swan-neck of the drain ?? You can check, and if not, the drain needed a clean anyway

If all you lost was the cap jewel and still have the chaton and hole jewel it's not the end of the world. A generic cap jewel with right diameter and thickness would work. Chances are you would find one that fits from assorted cap jewel sets if you don't already have scrap movements lying around that may have fitting cap jewels. You can start pulling your hair out if you lose the chaton/hole jewel though so definately be a lot more careful with those.

I will happily do my best for you. Will make contact with my Watchmaker friend.

Check out the link below. It gives all the applicable interchangeable movements and all the individual part numbers. Order by Inca part No. from Cousins.

Well, if you can help me out with this I'll be forever grateful! I downloaded the parts list for this movement from CousinsUK but can't find any references to the balance jewels whatsoever. Here are a couple of pictures from the disassembly of this particular movement (ETA 2772).

Thanks for all advice Endeavor, much appreciated and it will come handy in the future! However this time it won't help. The thing is, I didn't actually ping it, but was too embarrassed to tell you the truth. My conclusion is that it was in my cleaning glass jar when I washed out the the glass jar (way too painful to write about this in more detail), so it's on its way into the belly of a fish or so... Good thing I wasn't holding a gun in my hand when I realized my mistake... A spare part is my only salvation...

Get a strong torch and search when it's dark; if you are really lucky you may see some flicker. Did you check your hair, your eyebrows, your nose (look in the mirror !), inside your sleeves / shirt etc ? Best is to leave your clothes on the spot. When start walking through the house, you have no idea anymore. Check your shoe soles !! Of course if you have your desk on a carpet floor, than you are done and the lesson to be learned is to move your desk to a room with a smooth seamless floor. If the floor is smooth, and as last resort, get a new & empty bag in your vacuum cleaner and vacuum the whole floor without using a brush. Cut the bag carefully open after you are done. I once found a tiny, very tiny screw of a 17mm ladies ETA2450 back using the vacuum cleaner trick. Suc6 .......

Don’t loose parts and you will not have to visit Cousins too often. ronP

A quick blast of last post on the bugle, then move on to the next one. On the plus side, you now have an almost complete set of spares for an EB 8021-68, and you have learned a bit more about the art of watch repair, and who in this game hasn't had to admit defeat from time to time.

Just replaced the battery in my caliper. Here are the measurements: OD: 6.33mm ID: 2.86mm Thickness: 0.04mm

Here is part of my Seiko chronograph collection. From left to right: 1. 1975 with the 6139 caliber: The first automatic chronograph in the world in 1969 and also the first automatic chronograph known to be worn in space by the general Pogue in 1973. 2. 1983 with the 7A28 caliber: The first quartz chronograph with analog display in the world. 3. 1993 with the 6M15 caliber: Not sure if it's the first of anything but it has very interesting features like the chronograph with dancing hands. It was also created to celebrate the 500th anniversary of the discovery of the Americas. 4. 1992 with the 6M23 caliber: Another Seiko used in space, a "Space Navigator" worn by a Japanese astronaut during an US shuttle mission. 5. 2007 with the 7T62 caliber: Not much to say about this Seiko but it's the watch I wear when I am at home or sleeping. 6. 2013 with the V172 caliber: My most recent watch and also the only one that never gives the right time. Not sure what is wrong but the hour hand turns slower than the other ones. I have to use the buttom sub dial to check the right time.

Hi, yes you need it to make it work reliable all the time. just order withe Cousins on the UK. The part number is 2753, is in stock 3 pound a piece. https://www.cousinsuk.com/category/filter/eta-esa-movement-parts, or ask you watchmaker to order one for you. succes ronP

https://crona-parts.ru/catalog/655/51680/ Found some here. Cant help you with measurements at the moment because the batteries in my calipers are drained. Anything large enough to cover the center portion of the day wheel without peaking out the window and does not exceed thickness of about 0.2mm I think would do.

One of the tech guides I use.......whoops. lol. I plan to double check them and post just havent had a chance. Sent from my SM-G950U using Tapatalk

Just taking a W.A.G. here,that watch looks like a late sixties diver style watch.I am thinking it is probably the original crown.

There. I knew I've seen it in a tech doc somewhere. It's listed as the "indicator distance piece." It's not in the current version on the ETA website though.

i have a crono that might have the same mvtm., without the date wheel. i'll try to post it. vin

No, you cannot over wind a movement, that is a myth. As I have said before you need to demagnetize the complete movement. Bicycle pump. You need a proper blower, Watch suppliers stock them, this is what you need. Bicycle pump is to strong and could damage the hairspring.

Thanks for posting that - I’ve always loved barographs. I had similar issues with a Baro I found in an auction. I found sucking it hard and crimping the bellows did the job! The movement was in good nick, just needed a bush or two. I didn’t lacquer the brass - I just used renaissance wax (less fuss!)

Use ronsonol lighter fluid. It is safe to use. It won't harm any parts of the balance. You can leave the balance in the stuff for days. Use a screw top container because it evaporates very quick.

Yes check the coils you may have some oil contamination.

I would de-magnetize the whole movement. See if that helps. Just a tiny hair or speck of dirt can mess the timing up.

I would first check the balance & hairspring with strong magnification. Check that the H/spring is breathing evenly and all of the coils are not sticking together.

Hi I should take a careful look at the balance oscillation and the balance spring coils are not intermittently sticking during operation. You mention refurbished balance, what did you do.

Yes, there was a lot more learning in there than I expected. You will have fun with the sewing machine. I serviced an old sewing machine years ago for my wife and it took quite a while to understand what effect all the adjustments had. Interestingly she now has a much newer machine as she wanted more features, and that one has virtually no adjustments... presumably manufacturing accuracy has improved to the point where adjustment in the factory is not necessary and it’s designed to be thrown away when worn out . The barograph looked like such a simple mechanism, but understanding where the friction comes from to keep the hysteresis down is really important. It’s very easy to set the pen pressure too high and even that has a big effect. Also, it is recognised that the important thing a barograph does is provide a trend, rather than absolute point accuracy, so no need to chase my tail too far on that... so over night and this morning the pressure is rising and the weather is set fair . The gap in the trace yesterday is where I took it apart again to put a new link pin hole in the bellows attachment.

I’ve just pinged the jewel housing cap jewel for the lower balance shock block of my ETA 2772 and I’m absolutely devastated, especially as this a movement adjusted in six positions having a glycodur balance wheel and all (my first). The movement is in excellent condition and I won the watch on an eBay-like auction for a mere $60. CousinsUK doesn’t seem to have any spare parts for this movement (or the similar 2770 and 2782). I could kill myself for being so sloppy. Anyone who can help me out or give me some advice on how to proceed?

Hi all, Thanks for your help! Monday evening i gave the balance a little oil and blew out any bits & bobs through the movement with my bicycle pump. I also demagnetized the whole movement. It seems to have worked perfectly until last night where i just noticed it had crawled 2 mins ahead and then i reset it and againt crawled 3 mins in the space of 10 mins. I had then removed the watch and sat it on the table until the morning where it had not increased anymore time. Is there any chance that this could be due to over winding the automatic movement or is that not a thing.
