In Context

At 42 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 15 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 plexiglass crystal scratches easily but polishes back out at home, which sapphire does not. 60 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. 40 hours of reserve carries it overnight, but not through a weekend in a drawer.

ST 378.0801 Tele is one of 16 executions of the ST base reference. Underneath they are the same watch; what separates this one is a black dial and a stainless steel case. It was a limited edition. Introduced in 1973. Beyond the time it carries a chronograph.
