1974 Zenith Surf Hi-Beat watch, professionally serviced and sold with a 2 year guarantee. Hi-Beat watches are fascinating. 36,000 beats per hour means a second hand that glides around the dial with grace and precision. Industry standard for modern Swiss lever escapements is 28,800, which seems like enough, but when you witness a 36,000 bph watch it really makes you wish they were all so smooth.

The day/date complication adds a level of functionality that not many watches of this era featured. This is a great example from Swiss-staples Zenith.
