Seiko 6138-0020 Tokei Zara Speedtimer, serviced in June of 2019 in Japan. Running at +5spd on the timegrapher, amplitude in the 260s and 270s. Chrono resets as it should, runs as it should, everything works perfectly. On its original bracelet which fits a 7" wrist, watch needs a new crystal and relume to look good again (lume missing on the 7 oclock marker).
Price: 500USD net to me.
