I just bought A Mido watch pre-owned and certified COSC of course it must be a really accurate watch right but at least +/-10second a day worst
But this watch run fast like 1- 1.5 minutes a day...from the movement blue screws i see that the watch has never being serviced since it first owner,
I want to ask,does this watch need service or this watch got magnetize? Cause it just run fast 1-2 minutes fast and i see many articles say that magnetize watch can run fast to hours..

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

As I indicated above I did email the best pictures that I could see of all the pictures and I'm pasting the answer below. To really go beyond we need better pictures. Then the definition a better pictures is the impossible picture? There's a reference to the roller table which is totally invisible at all these pictures. In the early days of lever escapement's there are lots of variations of things. So the roller table located underneath everything engaging with the lever might have something clever. If your watchmaker with a loop it's easy enough to look in. Photographing that would be quite a challenge unless you knew exactly what you're doing. Then attempting to remove the balance wheel would not recommend unless you have experience with watches of this type. As because removing the balance bridge does not allow you to remove the balance wheel without underpinning the hairspring. Typically the hairsprings are pinned to the main plate. You will notice the reference to conversion to lever escapement. As technology changed the early movements would transition into newer movements. So basically they will take their older movements and start to add bits and pieces of newer technology on to them rather than making an entirely new watches. As for the fusee, I really can't make out any details about the escapement from those poor photos. It looks like a standard lever escapement but it has a verge style balance cock. The case marks look like London, 1830. This would be way too early for a standard lever escapement. Perhaps it started out its life as a verge and was converted to a lever at a later date. I'm pretty sure that the signature is James McCabe - a well known and collectible watchmaker. It would be interesting to see more details of the roller table. This could, for example, be a Massey lever. Better pictures would help.
Thanks watchweasol. I've had another look and it says the following at the bottom of the dial: Great Britain "46562 10878" JerseyMo, the plucky little watch isn't done yet. The auto-winding is definitely working. I've been checking in on it periodically and giving it a shake. It's ticking away as it should and the date advances, even if it's running about 12-15 mins slow over roughly a 12 hour period. I've warmed to it for sure. The bean counters can't mark this one off their spreadsheet just yet. Hello again Poljot. Is the "sophisticated" click just a piece of bent metal engaging the teeth? I think I'll have to investigate further and report back, after I've cleaned the DNA and grime from around the case back before I open it!
Good evening guys! So after work right behind watchmaking desk. I did exactly as I sad. Once I’ve put it together and tiny tweak, here is result from all mighty Weishi No 1000. Think I leave it that way. One more time thanks for all inputs. Cheers
