Mines amazing! I got it here (TYasimplefarmer!!!), its been lumed (VAC). I beat on it every day and it rewards me by keeping time +/- 3 seconds in 24 hours .
If I were to mod it further
A Clark crystal
replace the bracelet as its end link is skinny on one side by maybe 1mm
And just continue to beat it up then pass it on!
As for the movement, it would be nice if had a smoother sweep and the GMT hand which i use daily is a little tough to set perfectly best Ive gotten is 6 minutes off (GMT hand top of the hour minute hand at 6 after.
I could care less if the movement dies, $17.00 and I'm back in action!
GL!
