ETA Calibre 2772 Service Walkthrough Pictures – Assembly
(Please sort the pictures by name in ascending order)
For the disassembly sequence to make sense it is important that the pictures are sorted by name in ascending order. Generally, the sequence of pictures first shows the part to be removed in its position on the movement and the following picture shows the removed part along with any screws that held it in place.
For the assembly sequence to make sense it is important that the pictures are sorted by name in ascending order. Generally, the sequence of pictures first shows the part to be assembled along with any screws holding it in place. If needed, the following picture shows the section of the movement where that part is to be assembled along with my lubrication suggestion, and the picture after that shows the part when assembled to the movement.
Note that this is not a maintenance servicing tutorial. To be able to service a watch movement some basic tools are required as well as some basic skills. It’s not difficult but it requires a bit of practice and perseverance. I’ve used a lot of sources on the internet to learn about servicing and repairing but watchrepairlessons have so far not only been the best source but also the most affordable source I’ve come across. I am a patron of watchrepairlessons but I’m in no way affiliated with it.
Prior to servicing this calibre 2772, I’ve serviced an ETA calibre 2472 and two ETA calibre 2824-2s and the kinship between these movement is obvious. The 2472 is from the mid-60s, the 2772 is from the mid-70s, and the 2824-2 is from the early 80s. They all have the same type of distinguishing train. The keyless works of the 2472 and the 2772 is of the more traditional type whereas the keyless works of the 2824-2 quite a bit more sophisticated. However, the calendar works of the older 2472 is by far the more complex with its instant flip over of the date. It has been very interesting to study the similarities and differences between these three related automatic ETA movements.
Hello dear watchmakers!
I am now working on a SU movement, Slava 2427. It is a manual-wind movement with day-date complication
I am trying to assemble the watch back together after service but I am stuck on the day disc.
The day disc is fitted OK in my view, teeth underneath the disc interacts with the click and the disc advances naturally as other motion works move clockwise.
However, the problem is that the days written on the disc are not in the right position and do not fit inside the day window of the dial.
What could I have done wrong??
Good evening everyone. I am new to this forum and i can see we have some outstanding experts on the site.
brand new to watch repair and looking to get some advice. I purchased an Omega seamaster quarts 1342 watch (not currently working and not tested) as it was a bargain and understand that 329 is the equivalent of the original mercury battery used when the watch was manufactured?
I am hoping the battery change will mean it is functional but in the event it does not work, how easy/costly is it to repair. (I’ve heard parts can turn this bargain into a money pit)
would anyone in this community willing to have a go at fixing it after i try battery change?
paid service of course.
any help advice would be much appreciated
Hello.I have been working on a vintage movement. It is German movement, PUW 1561.
It is automatic and has date with quickset function by pulling and pushing back the crown.
Before I disassembled it, the quickset did not work instead the date changed as hands passed 00:00.
However, as I am trying to put the watch back, the date won't change either by quickset or just manually.
The date disk won't move no matter how long I move the hands. I think I have assembled the date function part wrong but I have no idea how the parts should fit it.
I read a post about servicing this same movement but it did not work for me. (http://watchguy.co.uk/service-arowe-puw-1561/)
Could anyone help me how to put the date parts back in?? I attached a photo of the movement I am working on.

This link goes a bit into the discoloration of glass by radiation and apparently is known as 'radiation browning' http://birns.com/uploads/file/Radiation-induced Discoloration.pdf The clock I saw it on had not worked for decades, had heavy radium paint on the hands and the hands had stayed in the same place over that time causing the discoloration of the glass inline with the hands.
I agree the yellow is age and its not glass it's plastic, its the blackening above the hands I'm talking about. I only mentioned glass as the only other time I've seen this was on the glass of a clock with radium hands. I also agree owning it wouldn't be dangerous, and if you are careful with cleaning it would be safe to work on this watch, but I'm going to pass on this watch as the evidence points to it having more radium paint on it than usual.
I finally got round to fitting a “proper” balance and it works great! I was a little worried at first as the timegrapher was showing snow, but managed to regulate it to at one point 2s/d and BE of 0.1 - so well happy The moral of the story if don’t be tight and get cheaper OEM parts....
