The Maen Manhattan 三七 features a thin 7.1mm case and 100m water resistance with a screw-down crown, utilizing a manual-wind movement with a two-day power reserve, while another reviewer points to a different movement with an average accuracy deviation of +/- 12 seconds per day and a 40-hour power reserve.
