Any feedback going from previous Seamaster 300M to new one?

Considering keeping my current blue Reference 212.30.41.20.03.001 to new one below Reference 210.30.42.20.04.001

Any feedback and feel of difference? Also planning to keep both!

I’d be interested in hearing about this too.

I’ve got an old Quartz 300M diver, and keep thinking one day I might add a new one.

I know it’s a bit bigger and quite a lot thicker, but it’d be good to hear opinions of people who’ve swapped or added.

Also interested in if the noise or feeling of the movement in this calibre is actually noticeable, or if you have to be really really trying to detect it. I’ve never heard or felt the rotor moving on any of my automatics.
