Good to know it's available. Haven't counted how many swiss eta pieces I have but its a few, and I later regulated out-of-warranty pieces.. much better but still unimpressed with their timekeeping, except for one 2824-2. OTOH, I have only 2 pieces with the 9015, but both of them keep spot on better than cosc time, 1 sec/4d. Were it feasible, I'd replace everyone of those swiss etas with 9015s.
I'm a stickler for accurate timekeeping. I remember reading in the Seiko forums of some commonly used Seiko movements that gain or lose only 1-2 sec in 3-4 weeks!
