Thank you! I do believe it was manufactured in 2021, the same year it was discontinued.
No, it hasn’t been serviced. Since it is anti-magnetic, the movement is resistant to magnets. It also has the Co-Axial escapement, less lubrication is needed (insert joke here) when being assembled, which reduces overall stress/friction in the movement, and lessens the need for servicing compared to non Co-axial movements.
Hope that helps.
