With four Seiko 6309-7040s going around in circles on the winder and then heading for a power reserve test, I had some spare time.
There was a small project that I thought I'd tackle. I picked up a little Seiko 6119 for peanuts and decided to do a restoration, starting with jewelling the plate and train/barrel bridge as most Seikos of this age and style exhibit signs of wear that causes barrel tilt and other issues.
After replacing the worn bush in the train/barrel bridge with a jewel, I turned to the plate. It was only then I noticed a strange "smiley face" on the periphery of the barrel arbor hole. I hadn't noticed it when I disassembled the watch as it was covered in buckets of dried black grease.
This is it (note, hole has been reamed ready for the jewel).

Any advice on what it is?
A - Manufacturing mark?
B - An
@STANDY style fix for worn arbor hole?
(He was a butcher in a previous career, thus the reference to him
).
I did notice some marks/metal bruises on the other side of the plate, possibly from being on a stake anvil?
Over to the gurus.
