Does a Seiko SLA043 62MAS slow down as it runs out of power? Surprisingly little!

Do Automatics lose time as they run out of power? No! A follow up to my recent Spring Drive video has me looking at the SLA043's 8L35 movement to see how much time will it lose as it runs out of power. I am using a Credor 8J HAQ as the reference time keeper and the net loss of time is surprisingly low.

Notes: The SLA043 starts out at 1 second faster than the Credor. I measure time at the 30 second mark as it's easier to read the second hand when it doesn't overlap the minute hand.
