Sicura Chrono 17 Jewel Finished


Recommended Posts

Hi guys, just thought I'd share details of the watch I'd just finished for a friend. The movement is an eb8420-73, the watch was sent to me as a non runner. After teardown, clean & initial inspection, I found the friction spring for chronograph runner was missing a finger & the chronograph second hand had stuck to the glass. ac500cc874a59c8ebad54b2836b07711.jpg6e97021bf0c761ff383f3c46382242c9.jpg0e44419f3b99d1ff0e6bf4e52786f0b5.jpg06a9160527be6a477548e0560f630223.jpg150eca271c05b2d5a4de1caa1070d6c0.jpgc904a6f6c976a28debd395ae667cc548.jpgf855ba50fab07da354e681a74b4103ee.jpg1dcd67814b974ee631006ddeb74e7509.jpg04d982e12a9b2ef00ab25917dc2ca76c.jpg842c79c117afdd0a06f1cc29a2128172.jpgad2039f1c844024134aa06c128c7de49.jpgc2fef5ab5856edd20f3a9c26c5eddb78.jpgb72cac6f54b93c126b730553ce227fee.jpg09f66e73f2d2f957952763d4586d1d15.jpgafter the rebuild I had a problem with the balance & end shake. Dial side down it ran ok'ish, but dial side up it completely stopped. First I tried a new complete balance, it did help but I still had issues. Then I managed to source a new balance bridge complete with balance etc.. & this resolved the issue. 5c96bf2a1ac44869a099bded45c60f5d.jpg988283e914493f06e1d712fa675b8ba4.jpgf85fe9a4fd8bc15e91c37c18c16b6b50.jpg2aed8e226a9e1f948928f326eb6f2f1d.jpg

I then stripped the second hand & chronograph min counter & resprayed with Matt neon paint 046265ff3549bef41ede184edd845ffe.jpgrelumed & replaced the glass with a high dome crystal. af97506c1853c69dfba600c8518813a2.jpghttp://images.tapatalk-cdn.com/15/11/09/5b655d63baa2e184e4a045a79ef98fd9.jpghttp://images.tapatalk-cdn.com/15/11/09/5169eec975882638ce2d19dc01856f3e.jpghttp://images.tapatalk-cdn.com/15/11/09/0091d0415802976c328fd91619efdc1f.jpghope you guys approve of the finished article.

Not every ones cup of tea, I have one, pin pallet as with yours.

I just found it in one of my boxes, just hated to see it not going, heavy old beast .

Cleaned and serviced mine too, they seam to have a bit of a following.

Well  got that one wrong, mines a Sorna, it's basically the same type of watch made in the 70s.

Still a nice looking watch buddy. I love the sport style with black rubber.

    • The part was how it fell out of the movement - the train wheel bridge wasn’t screwed in.    I’ll probably dismantle the part, if I can, to work it out.    The train of wheels ran fine - it was only once the keyless works were installed I noticed the problem. 
    • 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!    
    • 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
    • Back home...printing now.  Will report results
