Not long ago I received the Seiko SARN001.
A watch with one of the most complicated Seiko movements, the high beat 4S36. The watch has double retrograde and GMT.

I really love the quality on this one. Fit and finish are great. Though it is a very busy dial, I still can read the current time quite easely.
The movement specs:
31 Jewels
28’800 A/hr
Integrated auto-winding
Diafix shock absorption
Thermo-compensating balance and hairspring
Auxiliary manual-winding
GMT complications (independent)
Date indicator
Retrograde Day
50-hour power reserve with indicator
