Servicing an IWC FA Jones watch. Watch repair tutorials.

[Music] so i haven't uploaded a video for a few weeks and for that i do apologize it's been incredibly busy here in the workshop on top of that i've also had problems with my microphone and so i've managed to resolve that problem by getting a new one so today i'm going to be um stripping this beautiful iwc fa jones uh movement is a really lovely watch and um this came in uh as a dead stopper as it happens and it actually turned out to be the the the hack which stops the balance when you pull the the winder out um had managed to get itself jammed on top of the balance rim um no idea how that must have happened uh didn't look like the watch had been banged or anything um but yeah that's what happened and so uh i released the hack from the balance wheel and the watch started going fine um but it wasn't a brilliant um reading on the timing machine and on closer inspection it turns out that the lubrication was fairly dry and so it's really going to benefit from a full strip down um and a clean and a service so that's what we're going to do so right now i'm just removing the movement from the the watch case and uh i've loosened the the bolt screw and i'm about to take out the winder so that i can remove the movement so with the movement out of the case uh what i do is put the winder back into the into the movement this will aid letting down the power a bit later on so now i'm going to take the dial and hands off as you can see i'm using a plastic sealy bag in order to protect the dial whilst lifting the hands and the dial is secured with two dial screws around the edge of the movement so i'm removing the hour wheel and now the canon pinion so now i need to remove any residual power that's left in the in the mainspring this is done by holding the click spring whilst gently allowing the winder to rub through my fingers i don't like the mainspring to just snap down so now with the power removed from the watch i can remove the escapement and i'll start with the balance wheel and before i remove the pallets just to make a hundred percent sure that all the power is removed from the watch i'm going to take off the ratchet wheel in this case the ratchet wheel is secured with these three screws which is a fairly unusual setup quite often it's just a single screw in the middle of the ratchet wheel you see it's got a like a secondary wheel underneath it so whilst i'm here i can as well remove the crown wheel which is again has got secured with three screws quite often these crown wheels are secured with a left-handed thread screw or a reverse threaded screw and we have this like secondary i don't know what to call this to be honest with you it's like a um secondary ratchet wheel if you like maybe somebody will correct me on that so now i'm absolutely certain that all the power is out of the watch i can proceed now to remove the the pallets you can notice i'm using some peg wood to hold the pellet down [Music] whilst removing the screws this is because sometimes the pellet gets a bit loose could jump out whilst you're unscrewing and with the pressure of the screwdriver that could potentially damage the pet the pallet pivot or the pivots on the on the pallet so it's always useful to just use some peg wood to hold it down whilst you're unscrewing so now i'm going to remove the main plate which in this case is secured with three screws and this reveals the train of wheels and the barrel let's start by removing the center wheel there we have the third wheel and the fourth wheel now this fourth wheel has an extended pivot which holds the off-center seconds and of course the escape wheel and we'll just take out the barrel now here's the the balance hack it operates when you pull out the the winder as you can see any tension on the hack is released and it will touch the balance rim obviously stopping it as remove the rest of the motion work and uh quite often the setting lever spring will cover the whole lot but this is slightly different so we have this cover plate here which is uh holding the minute wheel and these two intermediate wheels and so in place of a certain level spring we have these two springs here and sorry in place of the setting labour spring and the yolk and um so we're gonna take off this spring which is acting as the yolk this is held by two screws here and sometimes these ping off if they're under tension so again i use peg wood just to hold it in place whilst i'm unscrewing as it turns out there was no tension on it but i was just being careful these screws are actually really quite tight so i'm being very careful not to damage the screw heads okay now so i'd like to take off the the setting lever and of course i'll have to unscrew the setting lever screw for that and the setting lever just fell to the bench as it would do now i can take out the stem and the winding pinion and the clutch wheel and with that we can see that the watch is disassembled and ready for the cleaning machine so now the watch has been cleaned through the cleaning machine anybody's wondering i do have another video which shows how to use the cleaning machine but in this case now we're going to start to reassemble now here we have the balance hack which i removed earlier however i didn't show that on the video and for that i do apologize but it was secured with this one screw and in this case it was a simply uh replacing the hack into this slot so now i'm gonna put the or replace the train of wheels and as i always do i've started here with the the escape wheel now the fourth wheel if you remember the fourth wheel has an extended pivot for the off center seconds hand now we have the the third wheel now i've cleaned and lubricated the mainspring inside the barrel i have plenty of videos where i've actually shown this in this case i haven't so the center wheel goes back in place as well now and before replacing the main plate let's not forget to position the setting lever screw now with the main plate in position we can make sure that all the pivots for the wheels are located in the in their respective holes before screwing down the main plate sometimes this can be a tricky job patience [Music] will get you through the day in this case there we go just checking the free running of the train and whilst i'm still holding the main plate with the peg wood so that it doesn't jump out of position i'm going to tack it down with one screw here i'm not going to over tighten this screw because first of all i'd like to make sure that the train is still free now i'm absolutely certain now i can actually tighten the screw and so now i'm going to oil the barrel upper bearing and i'm using d5 here and with that oiled i can continue to reassemble and here i'm fitting this extra sort of ratchet wheel shim if you like the actual ratchet wheel screws onto this with the three screws as mentioned earlier but first of all let's just oil the rest of the the dual holes and the center wheel i'm using d5 and i'll be using 9010 for the third wheel the fourth wheel and the escape wheel uh and so now i'm reinstalling the ratchet click and naturally there's a spring for the ratchet click yes and i'm lubricating the ratchet click with a little bit of grease oh you may notice i'm using brass tweezers for most of the reassembly uh specifically when picking up large objects and one of the reasons for this is this particular watch has a display back and of course it would be undesirable to leave scratches all over the place and so there's less risk of that when using brass tweezers so here i just need to line up the holes of the ratchet wheel so that i can screw that into place great and with that done uh now the next job is to reassemble the keyless work and i'll start by lubricating the clutch wheel and the winding pinion and now the stem can go back into place and now i'm going to refit the setting lever so we have the two springs uh that we referenced earlier one is acting as a yoke or return bar and the other one is acting as the setting lever spring it's a fairly unusual setup so i'm just replacing those now radical okay and so the operation seems smooth enough let's give it a quick test here yep the hack is moving nicely okay so now i need to refit the canon pinion and so first of all i'll grease the center wheel pivot but obviously before i fit the canon pinion i first need to oil the uh the bearing there again i'm using d5 here and whilst i'm at it i'll oil the rest of the train start with the barrel arbor bearing and we'll do the third wheel in the fourth wheel and the escape wheel just the same as we did before oh one thing i will note um is that the escape wheel has a cap jewel on on this particular watch and um i hadn't filmed it but i used a an automatic oiler and to oil the capsule so with that done i'm just driving home the canon pinion so now those are oiled i can refit the rest of the motion work and we have a little cover plate that keeps everything secure again checking the free running making sure nothing is snagging so all the train wheels are nicely lubricated we've fitted the helix work healer's work and the motion work so now moving on finally to the escapement and we'll start with the with the pallets as always um holding the pellet secure with peg wood whilst i'm screwing down so you have a tendency to jump out of position otherwise and that can potentially damage the pivots on the pallets so with the pallets in place i'm now refitting the balance and with the balance fitted uh i have to lubricate the endstones or the inca block shock system so i'll start be releasing the uh shock spring these inca block shock springs are hinged and so it comes out with one as a unit usually the end stone is friction tight inside the uh the setting so here's the end stone outside of the setting i'm just gonna apply some 90 10 and then 90 10 should cover some two-thirds of the end stone so the end stone back in its setting i'll just replace that and we'll do the other side so finally we get to refit the dial and the hands now you may remember when removing the dial earlier there are two dial screws situated around the edge of the movement dial screws are usually opposite each other on some watches there are three dial screws although that is more rare now the dial is refitted i can refit the hands first of all the off-center or sub-dial and you remember this goes on to the fourth wheel pivot which is extended just a little side note there and with the minute hand on all we have left to do is re-case this movement but before i do that i like to give it a good test outside of the case and to regulate it or calibrate it so i'm sure you'll agree it was a beautiful looking movement on these fa jones iwc watches uh i thoroughly enjoyed working on this one so as always thank you for watching and i'll see you next time you
