Master Ultra Thin Date Red Gold / Bucherer Blue

In Context

At 40 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. The 7.5 mm case is genuinely slim and goes under a shirt cuff without argument. 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. Its 38-hour reserve wants wearing most days; leave it off and it stops. At 28,800 vph the seconds hand advances 8 times a second.

128258S stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue sunburst dial with a stainless steel case.

Autoamatic movement with hours, minutes, seconds and date. 219 components; power reserve 38 hours.
