Why consider it

This 28 mm Seiko brings a mechanical movement and day/date display to a size often dominated by quartz watches. Its white dial and two-tone bracelet make it an alternative to larger steel sports automatics.

The tradeoff

The 11.2 mm thickness is significant relative to its small width. Expect to wind or reset it after time unworn; the stated reserve is around 40 hours.
