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.

    • Getting back to the issue which is us guys repairing or just enjoying horological exploits. The big worry now is how sound is Cousins as company going forward. The of cost if this 8 year legal battle will be astronomical. Cut backs will happen noticed already how the Cousins catalogue is half its size this year. The main supplier going out of business will hit the UK horological community in a big way.    On the Brexit issue it was about a sovereign country being able to make its own laws and trade with any country in the world. I cannot see what was wrong with this. For those who wish to re join the cost would be very high indeed.
    • Yes, it's the same (old) song and it's getting worse & worse;  
    • 🤔 leaving the EU meant that UK was no longer part of the convention and have already been turned down an independent reapplication. I'm pretty sure courts have to be held in Switzerland in this case. There will be a lot more watches stashed away in draws  tbh, folk wont be able to afford to maintain them. Cheap watches will be bought and top end watches by folk with plenty of cash that can pay for service and repair. The expensive once in a lifetime gifts and everything else inbetween will be at the forgotton when they stop working. I know i was being a numpty, get used to it 😄 Anybody that knows will boycott them, but besides repairers who will know. Nope will never buy one, i made that decision as soon as i learnt about this. 
    • although not in this case.  It was the Lugano Convention and its deficiencies that allowed a Swiss court decision in the first place.  This isnt really a Brexit issue at all.  A decision that affects both the EU and the UK should never have been heard in Switzerland. I bet the authorised service centres in the UK are pretty pleased.  It's a massive shame, though; I believe watch owners should be able to choose to have their watch serviced by whoever they trust.
    • Hi guys I think that old hippy is correct, it opens the gates for china to manufacture aftermarket spare parts. considering that they already do work on behalf of the Swiss I guess this decision gives the a little more legitimacy to tool up and I am sure they will take advantage of the situation either with or without the blessing of the Swiss watch industry  Having read about the protectionist machinations of the Swiss in the history of Europe they were the only ones to get fat at everybody else’s expense. I think the outcome could have been guessed at but ,  fair play to Cousins UK for standing up to them.  Now the question,  will everybody boycott Swiss watches and Swatch, no way they will still fill their coffers.  Me I stick with the Japanese once renowned for cheap shitty watches who came good through industrial effort and don’t for get the Russians that most dismiss as low grade crap. Wouldn’t buy a swatch product ever how about you all.? a
