ETA Calibre 2772 Service Walkthrough Pictures – Disassembly (Please sort the pictures by name in ascending order) 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.
