You posted this in January, which is not during daylight savings time. The SMT setting doesn't turn on automatic DST switching for a particular timezone; rather, it is a manual override to adjust timezones to DST when it is actually active. There is no automatic DST adjustment for this watch (according to their FAQ). Turn SMT to OF for all timezones during winter months, and ON for applicable timezones during SuMmer Time (SMT).
