Hi guys, just wanted to share my latest completed project. TBH I'm extremely proud of the results, as its the first watch I've done without any instructional videos or manuals etc.

I purchased the Watch for £50 off ebay as a non runner, partially due to the price & I've developed a liking of 36000 vph movements. When it arrived I immediately noticed the glass was cracked, dial had dirt spots & crown was stuck in the setting position. The case wasn't in particular good shape either. c3939888700c236a7554df8e97ec7d79.jpgafter doing abit of research on dial cleaning, ordering a new glass & a new mainspring I felt ready to take the plunge.

Firstly I removed the movement & cracked glass. 756cfa2d2cae27d9367cd0952e8aa638.jpgOnce out, I could see someone had sprayed the the whole movement with oil or something,it was dripping with the stuff. f3a543ec6bba6264f362e2d6d8ff59e9.jpgI removed the dial & placed it in a shot glass full of l&r extra fine watch cleaner. Left it for 10mins whilst dabbing the dirt spots & diamonds with an ear buddy, after a few more swills round I removed it & placed in watch rinse for a further 10 mins whilst doing shaking motion to adgetate any remaining dirt & finally a good rinse under the tap. A quick blast with the air gun & dial complete. Next, was the case. 1dff53e5be1f840d3540e7123417ea3d.jpgluckily it was a gold filled job, so a quick buff on the machine & a bit if autosol to finish. The case came up like new(well alot better anyway).

Next the movement. Complete disassemble & clean. 3bc539592abe24db9e91cefc53bac012.jpg16e87c4e3f6e09faa3bd1a4af63d2f44.jpgde2f87d33e463bbf496127bcd9960d20.jpg5889a1cecc62bf744faf471472f25497.jpgbd67636c6ddb0148cafbd59c0ec98627.jpg537a96f6fc43a81a1ec4732e1aca5523.jpg1751eae311dd7bcb154d620d6b49ce04.jpg3b170d5def14a7855cd2a3263579b786.jpg37f331cfdbd32dd94a2754964e3ad1e2.jpgfae0111d7ce0faf654bb48be9bc4a053.jpg5cacd68165e595ae4cb5291c08ffbc31.jpgb3324fe66a065e2e18bcacdd00cac05e.jpg353660d5d9051527b7ef533cdd5b7f51.jpg24e20ff20fac01bf85cb759f2cc349f2.jpgfinally the rebuild. This was quite a challenge as I didn't really have a starting point. I started with the mainspring & train bridge. It was after about an hour in I realised I should of started with the keyless as the screw that holds the stem in place is located slightly under the train bridge. However, it's a learning curve. After assembly, I put it on the timegraph, managed to get it in beat & regulated perfectly. Slight concern with the amplitude as I thought it would be higher933a9f169209ff3df1c4e8e59121d1ae.jpg however I proudly present my finished watch 170248579885447f28e2f62177cf4cd7.jpghttp://images.tapatalk-cdn.com/15/08/16/1b5d26f16bc7d24daa11add604ad8119.jpghttp://images.tapatalk-cdn.com/15/08/16/dc1353432ea983734fb9157a0342e27e.jpg

Cracking job, you should be well pleased. You've ended up with something a bit special for no money!

High praise indeed, Thanks Geo.

I only have one question. The day jumper spring! 3fccc12c8c0b574b6964d828f746d635.jpgshould the screw holding it in place be tight? I've just noticed while changing the date that the day wheel moves intermittently. I tried it tight & the day wheel wouldn't seat properly, so slackened it off & wheel seemed OK. Now after playing with it the date changes great & crisp, but the day seems like something is not right.

Thanks again guys for your kind words of encouragement. I can't believe I've just learnt something new which was puzzling me. The Crown would not go all the way in (stuck out maybe 2mm) I assumed that the previous owner had changed the stem & that's were his problems had started. However, this ties in with my day change issue. The Crown sticking out acts as a push button for quickset date feature. Thankgod I didn't chop the stem, that was going to be my next job lol [emoji1]

Great job done,nice watch. As a matter of interest as it has an unusual quick date setting function ie the crown is a bit proud has the crown stem got a seal to keep it water resistant.

Thanks for the compliment & I must admit, I've started to wonder about this myself. It may account for the movement being soaked with what I assumed was lubricant. But no I didn't see any seal on the case, stem or crown. Also, there was no gasket on the caseback.

Thanks for taking the time to look, I'd already downloaded that from cousins & your right. No mention of seals. I'm going to have a look at the stem this weekend to see if it's obvious that there should be a seal.

Very nice watch !!! You did quite an amazing job ! Enjoy it (or put at least $500 in your pocket ;) ) !

Thankyou Frenchie, I've decided to keep it, as it has now become the first of what I hope to be many of my 36000 vph fetish.

Excellent work! I hope to be that proficient one day!

Nice!

Your too kind Gary. I think I was lucky getting a good example to begin with. OK it was a none runner, but it was just the hack/keyless. I started at 10am & finished at 8pm lol. Not exactly a fast worker

      Balance staff sourcing?

      By mthomas828 · Posted

      Hello, I am about 5 months into watchmaking and I love it!   The attention to precise detail is what really attracts me to it. (and the tools!) I am working on a 16 jewel 43mm pocket watch movement.   There are no markings besides a serial number (122248) .  The balance staff needs replacement. The roller side pivot broke off.  I successfully removed the hairspring using Bergeon 5430's.  I successfully removed the roller using Bergeon 2810.   Did i mention I love the tools?! I removed the staff from the balance wheel using a vintage K&D staff removal tool  with my Bergeon 15285 (that's the one that comes with a micrometer adjustment so it can be used as a jewel press as well as a traditional staking tool...it's sooooo cool...sorry..  can you tell i love the tools?) No more digressing..  I measured the damaged staff in all the relevant areas but I have to estimate on some because one of the pivots is missing. A = Full length  A= 4.80mm  (that's without the one pivot...if you assume that the missing pivot is the same length as the other pivot (I'm sure it's not)  then A = 5.12 mm...(can I assume 5.00mm here?) F=  Hair spring collet seat  F=  .89mm   (safe to assume .90 here? .. I am sure that my measurement's would at least contain  .01 mm error ?) G = balance wheel seat  G = 1.23 mm  (1.20mm?) H  =  roller staff  H =  .59mm  (.60 mm?) B  = bottom of the wheel to roller pivot   B  = 2.97mm  (3.00 mm?)     here I am estimating  again because this pivot is missing. So my friends, and I thank you profusely,  can you point me in the right direction as to how to proceed? Do i buy individual staffs?  or an assortment?   Since I don't know exactly the name of the manufacturer, will that be a fatal hindrance?   Tbh, I'm not even sure what country of origin this movement is. Thank you!

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      Thats why i asked that question earlier, what happens if lubrication is placed directly on top of epilame ?  As opposed to walled within its non epilamed area . I'm not saying its right, i have no idea , just asking questions.

      thinking of where epilam should be removed did you know there was a patent that covers this? At least for the escapement I'm attaching it. GB1057607A-1 epilame.pdf

      Oh well, if Master @nickelsilver says it's the way to go, then it is the way to go! I stand corrected! 🫡 Are there any other places where you're supposed to remove the epilame from the contact point of rubbing? I don't think so! Thanks for the effort @Neverenoughwatches, much appreciated! 🙂👍
