Sorry for the delay with the progress report, but this has been one of these three steps forward and two steps backward jobs. It transpired that there were more issues than I first thought. To reiterate the obvious problems:- Centre Second Fourth Wheel - The gear wheel was off the shaft. Escape Wheel - The wheel was off the shaft. Auto Reversing Wheel - In bits. Oscillating Weight Bearing - In bits. Intermediate Ratchet Wheel - Separated. Intermediate Date Wheel - Separated. Lume on minute hand damaged Lume on dial stained with oil. The watch as received. I eventually worked out how so many components were in bits that come assembled from Omega. The watchmaker before me had tried to clean surface rust off virtually everything except the balance assembly, by soaking in rust remover which is phosphoric acid. This resulted in not only rust, but steel being eaten away allowing the wheels to fall off the shafts and pivots having a rough finish and being reduced in size. I had two attempts at assembling the watch, but unfortunately kept finding other damage. The eventual parts list required was:- Escape Wheel Centre Seconds Fourth Wheel Auto Reverser Wheel Bearing For Oscilating Weight Intermediate Ratchet Wheel Intermediate Wheel Escapement Lever Barrel Arbour Intermediate Date Wheel Ratchet Driving Wheel Third Wheel Cannon Pinion With Driving Wheel Mainspring Total Cost £320 (not helped by postage on multiple orders) THE ASSEMBLY. Starting point, the bare main plate. Keyless work assembled. Barrel bridge with wheels and click spring in place. Click plate fitted. Barrel, ratchet wheel, intermediate wheel, and barrel bridge assembly fitted. Escape wheel, third wheel and fourth centre second wheel positioned. Wheel train bridge fitted. Pallet fork and pallet bridge fitted. Date mechanism and cannon pinion with driving wheel in place. Date jumper located. Date ring retaining plates fitted. Wheel train and revering wheel located in the automatic device framework. Automatic device lower bridge fitted. Auxiliary reverser fitted. Oscillating weight bearing fitted. (I had to make a tool to tighten the nut) Oscillating weight fitted to automatic device framework, held by the three screws in the centre. Completed automatic device ready for fitting to movement. Balance assembly and oscillating weight assembly fitted to movement. Dial and re- lumed hands fitted. The new lume certainly works! Movement cased and running strongly. The scrap. The result! That's All Folks!

Junghans Chronoscope today - this has a 7750 movement under the hood.

Great job done Geo. A real pro job, lucky watch, lucky customer. Sadly this sort of repair will no longer be in our remit due to parts being unavailable.

Hats off to you Geo on an excellent resurrection. My only hope is that the guy who was responsible for the mess you inherited has either learned some watchmaking since, or left the industry altogether, so he doesn't inflict any more such devastation. What would be really amusing would be to find that he was an authorised Omega repairer, it would put the whole Swatch group restrictive supply policy into perspective. And on that point it's as well that you were able to complete the job before the restriction set in. I would imagine the AD cost for such a repair job would have exceeded the value of the watch.

Great work ! Thanks for posting all the details !

You have a PM. :)

Awesome Geo , what a terrific result , bet the owner is over the moon

Amazing work :) :) Thanks for sharing .

Now there's a chat up line! :D

Nice, I love these Bulova diver with the acrylic dials.. My Snorkel says Hi!

Bergeon sell them.. Dust_Cover_Bergeon_6759-2 by Micky Aldridge, on Flickr But I point blank refuse to pay that in this instance. I get mine from the bay seller below, and have eight of them now. They are just under €25 shipped. http://www.ebay.com/itm/271078711134?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
