Recommended Posts


Has anyone experienced a PF Nautilus stopping overnight when not in use?

This is not a review. Should have been posted in this section:


Your problem is called "bad power reserve".  It can be due to a number of factors, from you not moving enough to keep the watch charged to some problem in the movement. The only test I'd do to check if the movement is fine is to handwind it (50 turns of the crown) and see how much time it runs before stopping. At least it should be 24/30h.

If less then your movement needs a service.

I had a Miyota (is that a miyota 9015 based one, correct?) that had low amplitude and low power reserve and when I disassembled it the problem was in the mainspring barrel which was not properly closed.
