In Context

At 40 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 11.7 mm thick it is about average for a modern wristwatch. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. 50 m covers rain and hand-washing comfortably; it is not a watch to swim in.

The movement winds itself from the motion of your wrist. 48 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

1628430 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver sunburst dial with a stainless steel case. Beyond the time it carries a date.

Mechanical automatic winding movement, 230 parts, 28,800 vibrations per hour, 48-hour power-reserve. Functions: travel time-zone: hour, minute, small seconds, date; reference time: hour, 24-hour indication.
