Big Pilot Big Date Bucherer Blue

In Context

At 46.2 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 15.8 mm it is a tall case, and it will catch on a cuff. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 60 m covers rain and hand-washing comfortably; it is not a watch to swim in.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 192 hours of reserve puts it well past a weekend — several days off the wrist and it is still going. At 28,800 vph the seconds hand advances 8 times a second.

IW5105-07 is one of 4 executions of the IW5105 base reference. Underneath they are the same watch; what separates this one is a black sunburst dial and a stainless steel case. It was a limited edition. Introduced in 2020.

Hand-wound movement with a power reserve of 192 hours, featuring a double-digit date display, and a power reserve display on the reverse side.
