I just noticed this new Seiko/TMI Caliber, VH31.
I hadn't really noticed this before, but Seiko's smooth sweeping movements seem to be incompatible with any date wheel, and only offer day and date sub-dials.
A company on Alibaba is offering this movement as an option in a mid-range dive watch.
It's a 4 ticks per second (2 Hz), high torque, smooth sweeping, quartz movement. Seiko claims it will last 2 years on an SR920SW battery. I wish Seiko or Citizen would combine smooth sweeping quartz technology with solar/Eco-Drive, but I think that might be packing too much in a small space.
