Spring Drive

Fellow Freeks,
Is it true that the sweep of the seconds hand on a spring drive is the ‘smoothest’ out there?
Haven’t seen one in person yet and wanted to know your thoughts.

I love dive watches and if the above is true, then SBGA029 may become the grail watch that I will save for.

I don’t mind the fact that it is considered a hybrid (not a pure automatic watch).

Other than the SBGA029 and the 600M, are there any other Seiko SD dive watches out there that I missed?

36000 beats per hour as opposed to 28,800 or 21,600 for many purely mechanical autos.
