Seamaster Bullhead 930

In Context

At 41.5 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 14.5 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.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 60 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.

ST 146.011 is one of 16 executions of the ST base reference. Underneath they are the same watch; what separates this one is a brown dial and a stainless steel case. Introduced in 1969.
