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.

Being able to service the ETA calibre 2824-2 was a long-term goal and a dream when I started servicing and repairing watches some years ago. However, my first “calibre love” was the Vostok 2409; a reliable Soviet/Russian 17 jewels manual workhorse without any complications which has been around since 1970. It is still in production and found in Vostok’s Komandirskie series of watches, by some called the AK-47s of the watch world, together with its bigger brother the Vostok Amphibian dive watch.
Modern-day Vostok Amphibians use the automatic Vostok 2415 (w/o date complication) and 2416 (with date complication) calibres, but the Amphibian that I’m servicing in this walkthrough, an Albatross Radio Room, popular among collectors, is from the 1980s and in those days the manual 2409, as well as its predecessor 2209, was commonly used in the Amphibians as well as the Komandirskies.
While I was servicing this watch, I noticed that the crystal didn’t fit perfectly in the watch case. Being a serious dive watch originally designed for the Soviet navy this was, of course, unacceptable, so I replaced the crystal and video recorded the event in my “Bergeon No 5500 Crystal Press Review”.
For me, the 2409 was a great movement to get started with as it probably is the most affordable movement on the planet, and spare parts are readily available and cost next to nothing. A lost or damaged part never spells financial disaster. Also, eBay offers an abundance of used Vostok watches in decent condition housing this movement for as little as $20 and sometimes less. A brand new Vostok 2409 (www.meranom.com) can be had for as little as $27. Be aware that, almost without exception, the eBay listings always state that these Vostok watches have been serviced, but in my experience they never are. Well, maybe dipped in a can of naphtha, left to dry and then injected with a bit of oil here and there. I’ve seen horrible examples!
A somewhat tricky bit about the 2409 is to remove and replace the anti-shock springs. For this, I use a self-made tool made from peg wood. It’s shown in one of the assembly pictures together with a description of how I made it. A very similar tool is demonstrated in this video.
Later, as I was working myself through Mark Lovick’s watchrepairlessons.com courses, I trained with the Unitas 6498 pocket watch movement which is the selected movement for the courses. In all honesty, from a learning point, the Unitas 6498 would have been an easier movement to get started with (especially the anti-shock springs), but the tinkering with the Vostok 2409 was a low-cost and fun way to get started and made me better prepared for the courses which answered a bunch of questions and was amazingly instructive.
Eventually, I plan to publish a “Vostok 2414 Service Walkthrough”. The 2414 is identical to the 2409 but adds a very uncomplicated date complication.
So, if you want a whole lot of fun for next to nothing when it comes to money, there is no other movement I would recommend before the Vostok 24XX movements, and the 2409 is a great starting point if you have a desire to begin tinkering with watches. Be warned though; tinkering may take over a substantial chunk of your life!
