This was given to me by a friend wondering whether it was possible to clean, the watch wasn’t DOA.
After a clean, small modification of the balance spring and a repair of the balance bridge it was ticking away.
Notice the heavily jeweled minute wheel, necessary or not ? or was this an attempt to “up” the jewel count that it could be deemed as a more expensive watch?
A great article can be read here regarding the use of “Irrelevant” jewels in Movements – the AR series is mentioned at the bottom.
