  1. ST96 Restoration Walkthrough I got a new project to start on: restoration of my brother's watch he got for his 9th birthday. This is not an expensive watch in dollar terms; but the memories and history are priceless, and one I really want to restore to excellent condition. It stopped running decades ago, but he has still kept this watch for nearly 40 years, how many of us can say the same about their first watch?! My brother has placed a lot of trusted in me to restore this watch, and I want to repay that trust by restoring this watch to the best of my ability. Note his name (blocked out) and date it was given to him are engraved on the back plate. After opening the back I was pleasantly surprised to see it was a 17 Jewel movement ... so for it's day it was a proper watch; and not a cheap throw-away item you buy at a service station. This would have been purchased at a professional jewelers back in 1975. Unfortunately, the first issue was discovered. The locating ring is missing, and the only thing holding the movement in place is the stem ... not good. So the disassembly begins. Once removed from the case, the hands and dial were removed to get to the movement. Then the first of the motion work is to be removed. Remove the Hour Wheel Then the Minute Wheel pinion and it's Guard Plate. Next remove the intermediate pinion for the Minute Wheel. Also notice the over oiling of this movement, someone got very enthusiastic with their oiler! Again oil everywhere! Here's is the Minute Wheel glued to the Guard Plate with oil. Pull the Cannon Pinion and remove the Endstone. Release the spring tension from the Mainspring. Remove the Ratchet Wheel and Crown Wheel Look at the flood of oil over the bridge! Second issue with this movement. The thread for the Crown Wheel Screw is stripped. It looks like someone has been inside this watch, many years ago, to try and see why it stopped running, and unscrewed this anti-clockwise; not knowing that it's a reverse threaded screw, and stripped the thread :( Continuing with the dismantling ... remove the Click and Click Spring. Note the orientation of the spring. Remove the Barrel Bridge Remove the Balance, Pallet Fork Cock, and the Fork. Remove the Centre Wheel and Third Wheel. Remove the Escape Wheel and the Mainspring Barrel. Remove the Endstone from the Centre Wheel Bridge, and then remove the bridge itself. Remove the Centre Wheel Whatever lubricates were used on this movement it has crystalized into a nasty mess. I tried to capture it on this photo, but it didn't really comes out as I'd hoped .... but notice all the white specs. To finish off, remove the Keyless Work. Start with removing the Setting Lever Spring. Next unscrew the Setting Lever, remove tension from the Yoke Spring, and then remove the Yoke. Note: more evidence of over oiling it present here. Note the orientation of the Yoke Spring. Lastly, remove the Endstone from the Main Plate, and you are complete. After fully dismantling the movement, I opened up the Mainspring Barrel and found what the original issue must have been ... a broken Mainspring. This is the third issue that needs to be addressed to restore this movement. Probably broken by a young boy over winding his watch :) Note: The break in the spring, and how it doesn't attach to the Barrel Arbor any more. So with a missing Locating Ring, stripped Crown Wheel thread in the Barrel Bridge, and a broken Mainspring: I need some spares!! .... off to the Fleabay .... Being a movement in an obscure brand of boys watch, I wasn't exactly hopefully in finding spares readily available ... but praise the Lord Jesus Christ, they were there in abundance! It seems India has cornered the market on ST96 Movements :P They had it least 10 to choose from. I ended up choosing a "Rare" Tressa model in "Excellent" condition, that was a "MUST SEE" I placed an offer for AU$28 on this rare collectable (including shipping) and won it **chuckle** Regardless of the hype, it is guaranteed to work for 12months, and is the movement I require to secure the parts I need. Including that all important Locating Ring. With free shipping comes a long wait for delivery to Australia ... 12-22 days. So while I'm waiting for the watch parts to arrive, I'll clean up the case and bracelet. ... to be continued
