Seiko 6F24 Tidal Chronometer

Nothing really exciting here
two points I found interesting, I was rather disappointed by the huge black plastic spacer, but if Seiko can pack all this functions into a small package, why not.
The other interesting point is that the second crown at 9 o'clock is purely mechanical and only connected to the inner turning date bezel. The battery is SW 920 and has been removed for this picture.
