My dear NSA finally came back home yesterday afternoon after a long journey of exactly 4 months.
Apparently this delay was caused by the summer holidays in Swizterland. The date of repair on my certificate is October 02, 2012!!
As far as the work performed:
A) My bezel is now perfect, it clicks the way I like it (should be) and the luminous triangle is now straight.
B) It seems to keep much better time as since 4:00 o'clock yesterday PM, it has not gained a second.
C) Since they performed a complete overhaul, my timepiece has been polished and looks like a brand new one.
Conclusion:
Was it too long? Yes
Am I satisfied? Yes
Regards,
Yves
