With all of the rusted parts replaced, everything cleaned and re-lubricated, this great piece of ’70’s bling is back in fighting form. The case incidentally has been through the ultrasonic cleaner for a spruce up, and the crystal has been polished to remove all of the scratches.įinally the rotor goes back on prior to closing up.Īnd the end result, looking a whole lot better and running like a champ. The reassembled auto-wind module goes back on.īefore going back into the case. Turning things over the cleaned up keyless works go back together. Then the balance goes back in and starts straight away. With the pallet fork reinstalled the escapement can be lubricated. The L&R Extra Fine cleaning solution has even done quite a good job on the staining that marked the train bridge. The pivots are oiled and the train checked for freedom all is looking good. The train bridge, barrel and barrel bridge, and crown and ratchet wheels back where they belong. Then with the balance moved back out to a safe place the train wheels, complete with replacement third and escape wheels go back in. The balance temporarily goes back so that the Incabloc settings can be reinstalled and the shape and condition of the hair spring can be properly checked and adjusted if necessary. It’s just easier and helps to avoid distorting the spring.īreaking grease is applied to the inside of the barrel walls (Moebius 8213 in this case) and the main spring and arbor go back in. I always use a spring winder when reinstalling a main spring. Reassembly starts with the main spring barrel.
ROTARY WATCH REPAIRS FULL
Fortunately I have a donor movement so all the required parts are ready to hand.Ĭontinuing the strip down the main spring grease has dried to a crusty goo…Īnd the auto-wind module looks relatively unscathed apart from little bit of rust staining.Īfter removing as much of the rust as possible using peg wood, followed by a full cycle through the cleaning machine things are looking a lot more hopeful. So I have to source replacements for the winding pinion, sliding clutch, third wheel, escape wheel, balance cock screw and dial foot screw, and of course the crown gasket needs sorting. The third wheel pivot jewel in the train bridge is encrusted. This is clearly what eventually stopped the watch. The third wheel and escape wheel pinions are toast, and there is rust staining around all the teeth of the center and fourth wheels, suggesting that the watch did run for a while as the pinions were rusting away. With the crown wheel out of the way the rust staining is found to have spread.Īnd once the train bridge is off the true extent of the damage is revealed in all it’s horrific glory.


The winding pinion and sliding clutch have pretty well had it suggesting that a failed crown gasket has let moisture in through the case tube.Īnother look at the movement shows moisture staining spots on the train bridge. This dial screw is as rusty as the balance cock screw and there is rust staining on the movement edge.Īs the strip down proceeds more rust comes to light on the keyless works, and it is obvious that most of the dark specks of dust on the movement are loose rust particles. With the movement out of the case the dial is found to be as grubby as the rest of the movement, but not damaged. The movement really is quite dirty, and the first sign of problems becomes evident the balance cock screw is very rusty. I take the winding rotor off before un-casing the movement as it reduces the risk of damage. With the back off things are looking a bit grubby and there is no evidence of any oil any more, but there is no indication of any serious issues.

This gorgeous chunk of 1970’s stainless steel has certainly seen a lot of use and is looking rather sorry for its self, but it stopped working and eventually found its way onto the open market for spares or repair.Īnd here’s why this watch was special it commemorated Frank & Eileen’s silver wedding anniversary in 1974, but it is sadly now a non-runner. It’s always rather sad to see a special watch, given out of love to recognize a special occasion, consigned to the bin after years of service because it has stopped working.
