  1. Hi guys.. Sharing a few pics a Slava I got off the 'bay. Sellers pic was a bit blur but it had a movement I liked and was advertised as running. The crystal was pretty scratched up but it was running. A Russian 2 piece case back. Quickset date by pushing this ..well..pusher! As you can see , the crystal has a very high 'rise' and this contributes to the overall thickness. And this is the reason I bid for this watch..it has a Slava 2414 (or maybe a different number as it has day and date) with twin barrels. It looks pretty clean and the finishing is slightly better than the other Slava movements I've seen. Its running pretty well these last two days but I'll probably tear it down and take some pics and post them here. I spent a few minutes with some sandpaper and autosol and managed to clean it up a bit. Interesting dial with some constellation around the edge of the dial and some Russian words where a minute track would usually be. Also some numbers. Anyone can shed someone light on this? Or speak Russian? Hope everyone enjoyed their weekend. Mine is almost over as its 9pm here in Malaysia. Anilv
  2. 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?? Thank you!
  3. Hello forum im new here and i wanted to ask for some advice I have a SLAVA watch which hasn't been used in a long time Had it serviced and the first and the second day it started to stop at 11:10 pm and the second day stopped at 10:55 pm. After that it works fine What could it be ? Should i send it back in to get it checked again or wait another day ?
  4. Hello all! I am doing this because I couldn't find any detailed information on this caliber, except some general photos. So I sort of explored it. Yes, I was an explorer, so please forgive the clumsiness! This is going to be more of a parts list presentation then a proper tutorial. I don't know what the parts are named, but I will try to explain what most of them do, from my understanding. Also this is the first time I opened a chronograph-like mechanism. It is a 24 ligne (55mm!!) russian rattrapante timer Slava 5498. Everything in it is huge comapared to any decent watch. It has 36000bph though so it is able to measure one tenth of a second, like a propper timer. It also has a Breguet hairspring on that huge balance wheel. I will call the two seconds as follows: the master seconds (or the second (2nd) seconds wheel, because it's at the bottom) which runs continously if you start the timer and the slave seconds (or the first seconds wheel, because it is at the top) which stops when you press the left pusher and hurries back after the master seconds when you push it again. Beneath both of these seconds hands lies the minute wheel which records 30 minutes. The middle pusher winds the timer. It also starts and stops the timer. When you press it, it both hacks the balance wheel and also hacks the master seconds wheel - it sort of needs two brakes to stop the beast . The left pusher stops the slave seconds wheel and, if pushed again, it allows it to quickly follow the master seconds wheel. The right pusher works only when the timer is stopped (via the big knob in the middle) and it resets all the hands to 0, except for the slave seconds wheel which, if stopped (from the left pusher), it stays in place. A couple of reference photos of the movement: The following two levers stop and release the slave seconds hand. They are acted by that column wheel (it certainly looks like one, but it has fewer functions then in a column chronograph). Next comes the spring that hold the column wheel in discreet positions, and the one that acts upon the lever that increments the column wheel: Next comes left pusher lever together with its piece that increments the column wheel: Next is the column wheel: I now take out the dial. For the picture purpose I leave two screwdrivers inside the movement to indicate the dial feet screws. I didn't take a photo when I pulled out the hands using a presto tool. Next I take out the slave seconds wheel and its cock. It sure is a long seconds hand axle. Beneath it you can see the lever with its spring which helps it follow the cardioid (heart piece) on the master seconds wheel axle. That lever has a rectangular jewel at it's end to minimise the friction - if you look closely you can see it is damaged. Also the cock jewel isn't hallowed but it is a sort of cap jewel that doesn't even touch the axle. Next I take out the intermediary chrono wheel: Next I take out the master seconds bridge - it is held by three screws. I do not disassemble the whole thing because I don't know how at this moment. To take out the Master seconds together with its bridge you need to stop the chronometer so the balance hack could get out of the way - so you could have access to the Master seconds hack screw to release it a bit so you could take the master seconds hack out of the way (long sentence!): Next I wanted to release the tension from the mainspring but I didn't know how to. So I cheated! I took the movement out of the case and looked at it from its side (I will show you how to get the movement out too). So there is a cutting on the side of the movement in which you can see a click appear when you wind the watch. You must hold that click with a 0.8mm screw and release the mainspring tension in a controlled manner - at least this is what I did: Now I show you how to get the movement out . It I expected two case screws but I was wrong. Russians used a simpler way: one screw combined with one stud. You can see the one screw that has its head cut in half near the balance - you unscrew it and release the movement. Now you can see the stud, diametrically opposed: I forgot to tell you that I 3D-printed a movement holder for this 24 ligne movement: Now you can better see the click: Now I take the balance out. That is one big balance wheel! And the pallets together with their bridge: Next I take out the intermediary chrono wheel holder (the equivalent of the coupling clutch). Carefull! It is hold only in one screw the one from its right. The bottom one is an excentric. I learned it the hard way - it was a 50/50 chance and I didn't win Next I take out the driding wheel. You can see in the photo that the escape wheel and its cock are missing - I didn't take a photo of those. Next I start on the main timer mechanism. I appreciate that all the springs are secured with a screw. It helps quite a bit! So you can see that it is a cam chrono after all, though the cam is also the balance hack. The column wheel is only for the slave seconds wheel operation. The Master seconds reset hammer has a stud between it and the minute reset hammer on the bottom side - you cand see it right about in the middle of it - I will show it to you later. I take out the sliding operating lever: Then the cam and the reset-blocking lever: Next goes the seconds hand reset hammer and the stud to the other side: I also take out the springs for the sliding operating lever and the master seconds reset hammer - carefully - the screws are not the same! I take out the train bridge. Check out the dirt! If you look closely, the ratchet wheel has two broken teeth - I didn't notice it before - the timer didn't present any problems during winding... russian stuff! Barrel and mainspring: I take out the crown wheel: And the click and its spring. You can see between them a ratchet wheel tooth I didn't tell you but in the mean time, on the bottom side, I had taken out the minute heart. It angages the minute wheel via a spring and it permits the recording of minutes and the reset of the minute recorder. It resembles a canon pinion with a different design and purpose. The bottom side: I take the hammer and lever out: Finally, the parts list: I will let you know how it goes when I will put it back together. Thank you, Bogdan
  5. Hello! I measured the old spring in the Slava stopwatch that I opened here: The numbers are: 480-520mm/2.74mm/0.39mm, give or take a couple of microns I couldn't find this combination on Cousins. Does anyone know where I could find one? The ends are like this: Thank you, Bogdan
