Design is relatively massive and very stable. Band is dibasic. Clock is a quartz clock accordingly exactly. The time adjustment is a little odd. The hour hand can be adjusted by itself. This is nice if you change the time zone or change from summer time to winter time.
However, the clock is then stopped again while wearing (walking and cycling). This is obviously disappointing. However, the battery seems to be OK, because lying on the dresser it is always running.
