Vostok 2409 Service Walkthrough Assembly Pictures (Please sort by name in ascending order)
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!
First part of the disassembly, fixing and reassembly of my new Seiko 7T32-7C20 Flightmaster Chronograph that recently bought as defect.
The damage was caused by trying to manually setting the date at around 11:30PM, when the watch usually starts to change the date automatically.
Enjoy the first part of the video.
I was asked to have a look at this family heirloom just handed to me from a friend of a friend as it was not working and they thought it may have some value. The quality of the movement did not inspire, to say nothing of the identity of the watch !!!
As I had never done a pin-lever before I decided to have a go and get it running again. On inspection I found it be in reasonable condition but very dry and the balance was very stiff and not working. Once the balance and lever were out all ran freely, so I reckoned a good clean and lube would solve the problem.
For those interested I have done a walk-through for the assembly as the strip-down is just the reverse basically.
After a good clean of all the parts in lighter fuel (I'm only a hobbyist) and a strip and relube of the mainspring, the assembly followed
First the gear train, block for stem gears and intermediate wheel were assembled and lubed
Next the barrel was installed (sorry for quality of pic)
Then the train wheel bridge/plate was added and checked for free running from barrel to escape wheel, and lubed
The keyless works are added and lubed, note the yoke also acts as a spring against the setting lever and action checked
The winding wheels and the unusual click spring are added and lubed and action checked.
I forgot to take pic of this next stage but the assembly can be seen in the dial fitting below.
The pin-lever was added and checked for kick The pins and escape wheel where epilame treated and oiled with M941, and the fork was wiped with M941 on a wedged end of pegwood, this is because they are all metal to metal contacts. Even the balance table jewel is metal !!
The balance was added, lubed and checked for function. There are no balance pivot jewels (in fact there are no jewels at all !!!) just holes in the main plate and balance cock. The holes lie under the round plate on the mainplate and the regulator on the balance cock. These were removed/lifted to lube with M9010, the cock plate being a bit tricky/delicate.
The canon pinion was added and lubed. This is not a friction fit but is driven by the intermediate wheel.
The minute wheel and dial washer are added and lubed
The dial has split posts which are just spread open (what technology !!) so this was fitted very carefully so as to avoid damaging the balance or lever which are very close by as shown in pics
Stuck in on my timegrapher which showed a very noisy trace (not surprisingly) but managed to get it reasonably regulated despite iffy beat error and rates in some positions. I aimed at a reasonable rate when worn and it actually keeps fairly good time within 1 minute a day on average.
The hands are fitted, and the movement put into the case-back and case-top/bracelet are refitted.
AND NOW I CAN REVEAL THE IDENTITY OF THIS HIGH END WATCH
Yes its a really awful 1970's fake !!!!
So no family fortune here then !!
Good day, guys! This is my little way of giving back to this wonderful community.
We usually receive for repair a watch handed down by a father to his son. In this case, its a watch given by the son to his father - a Seiko 5 from the early 1990s.
The watch has seen better days, with its hardilex crystal beaten and the watch not moving at all regardless of the amount of shaking you give it.
The hands are corroded and the dial mounted on the movement using contact cement.
I'll skip the disassembly and show you how the Seiko 7009 movement works. The Seiko 7009 technical guide is easy to find on the net though.
First to be mounted is the center wheel that drives the cannon pinion. After which I install the escape wheel and the center wheel bridge.
The third wheel and fourth wheel is installed next. Note that the fourth wheel drives the second hand directly. Then the click comes next.
Prior to installing the unified barrel and train-wheel bridge, you have to install the pawl lever and first reduction wheel assembly. The assembly is held in place by the first reduction wheel holder. Take note of the orientation of the pawl lever.
I find it difficult to install the barrel and train wheel bridge while ensuring that the click spring doesn't get in the way.

Ronda 715 Service Walkthrough
I thought I'd post a walkthrough on a simple quartz movement for people who are just starting out in watch repairing.
The Ronda 715 is an excellent movement to begin with, as it's simple in design; but has all the components needed to practice your skills on.
Even better is that it only cost around $10 to buy this movement brand new online. So if you break it or loose a part, you learn from the experience, and just buy another one :) Perfect!!
The Ronda 715 is found in many of the "Fashion" brand watches, like Guess, JAG, Loyal, etc...
As this is a walkthrough for novices there will be arrows to every part as we disassemble this movement.
I also recommend you download the Tech Spec PDF and get familiar with how to read them.
Here's the link to down the PDF
Remember to have fun!! :lol: If you start to get frustrated, just have a break and come back to it later.
Patience and perseverance will get you there, and once the skills are mastered it's very rewarding.
Ok, lets begin
Firstly, you identify this particular caliber of movement by the number stamped into the plastic surround.
As you can see this one is stamped "715"
The tools you will need for this service are as follows:
Bergeon 4040 Movement Holder An Eye Loupe, or some type of optics 3x or better Pegwood 0.8mm Screwdriver 1.2mm Screwdriver Tweezers Hand Lifters A Hand Setting Tool A Parts Tray with cover And a piece of Rodico
Since I am using a movement purchased from CusionsUK, I unfortunately don't have Hands or a Dial to remove.
If you are servicing a movement presently in a watch, I suggest you watch one of Mark's video's to see how you remove Hands and the Dial.
Mark's Videos are a fantastic resource to show you proper technics, and I highly recommend viewing them.
They can be found here: https://www.youtube.com/user/jewldood/videos
Once the Hands and Dial are removed, we then need to remove the battery, if one is installed, before we begin disassembly.
On this movement it is done by gently pulling the Keeper Arm back away from the battery.
Be careful when doing this so that you don't slip and damage the Coil.
Then turn the movement over and remove the 4 screws, using a 0.8mm Screwdriver, that hold down the Date Indicator Guard, and remove it.
Here is a reference photo of the Date Indicator Guard and screws.
Next, hold down the Jumper Spring with Pegwood to stop it pinging away, and remove it with your tweezers.
Then remove the Date Jumper and Date Indictor Ring.
Next remove the Indictor Driving Wheel
Then the Date Indicator Plate
Followed by the Hour Wheel.
Next remove the Setting Wheel
Remove the Minute Wheel
Remove the Secondary Yoke
This completes all the components on the dial side of this movement.
Turn the movement over in the holder.
Unscrew the 3 screws, using a 1.2mm Screwdriver, that holds the Module Cover Plate, and remove it.
NOTE: One of the screw is unique and larger than the others, remember it's location.
Here is a reference photo of the Module Cover Plate and the 3 screws.
Next remove the single screw that holds the Circuit and the Coil.
Then remove the Circuit VERY carefully and store it somewhere very safe.
Here is a reference photo of the Circuit and screw.
Next remove the Coil by lifting it with the end with no circuit tracks on it, as shown below.
Now unscrew the 2 screws, using a 1.2mm Screwdriver, that holds the Train Bridge and lift it off gently.
Here is a reference photo of the Train Bridge and screws.
Next remove the wheels of the train carefully, then the Rotor and Stator.
From left to right there names are: Third Wheel, Second Wheel, and Intermediate Wheel.
And here are the Rotor and Stator.
Unscrew the single screw, using a 1.2mm Screwdriver, that holds the Centre Bridge and remove it.
The Cannon Pinion should be on the centre post of the bridge and come away with it.
NOTE: This screw is also unique with a thicker head, remember it's location.
Here is a reference photo of the Centre Bridge, Cannon Pinion and screw.
Next remove the screw, using a 1.2mm Screwdriver, that holds the Plastic Setting Lever Cover, and remove it.
Here is a reference photo of the Setting Lever Cover and screw.
Then lift out the Setting Lever and Primary Yoke.
Lastly, pull out the Stem and the Sliding Pinion should fall to your work mat.
You have now completely disassembled the movement ... WELL DONE!! :)
The black plastic outer ring can not be removed, it is riveted to the Main Plate
All the parts can be put in the cleaning machine or Ultrasonic ... EXPECT THE FOLLOWING PARTS!
Battery Circuit Coil Rotor
I hope this was a fun movement to begin your journey into watch repairing, and that it builds your confidence to advance further.
Assembly will be posted soon...stay tuned!

Take a clear photo of the back of the clock, just the works, not the legs. Someone with the Horolovar repair guide might be able to identify it. If it has a disc pendulum there might be a number stamped or written in pencil, this should match the main number, if the pendulum is original. 3 or 4 ball pendulum will not be numbered. Bod
