It's an excellent piece!!
According to the instruction booklet, power reserve is rated at least 50 hours, which is impressive given that it beats at 36k bph.
The minute and hour hands are rhodium plated, centre seconds hand and power reserve hands are blued.
Movement wise, I don't think there's much that need to be said about the base movement... tried and tested since 1969 with minimal changes... says alot about it's reliability.
Make sure it gets serviced every 5 years and I am sure it will outlast you... lol
I have own 2 iterations of this model previously.
Both in 40mm and 45mm... They are beautiful watches. Just not for me.
I am more into sports watches.
Although the design is abit different, the movement is the same EP caliber 4021.
Open heart on the dial is a bliss, you get to view the escapement moving in superspeed so to speak...
