Power reserve on an Asian Swan Neck movement

Recommended Posts

Hey folks,

Can anyone tell me approximately how much running time I should get out of a manual wound Asian Swan Neck movement? I've been using the search function for about 20 minutes and cant find any reviews.

I'm using a movement serviced by The Zigmeister about 2 years ago.

Thanks for the help :)

56 hours if fully wound

If your 6497 manages to get that much of a power reserve, don't ever give it up :) Even ETA says to only expect 40 hours, but I have a few that make 48 to 52 hours, but I've never heard of 56 - that is one finely tuned movement :D

Yeah, that's the high beat - the standard 6497-1 is 46hrs (sorry thought it was 40hrs for some reason, too many numbers going around in my head I guess). Anyway I just checked the ETA data sheet and low beat is 46hrs, high beat 56hrs. One easy way of telling if yours is low or high beat is by comparing the teeth on the centre wheel against another of a known beat - the one with tighter grouped teeth (meaning more) is high beat, the one with less teeth (or more space in between them) is low beat. The Asian movements are on par with their ETA counterparts as far as power reserve is concerned.
