remarks
The old Inter ``Injunior'' with the IWC logo written in cursive is now in stock.
This model features a stepped dial with the date display located slightly closer to the center.
The main case is made of 14K top gold and has a waterproof stainless steel screw back.
The movement installed is a low beat machine Cal.8531 with a frequency of 19 800 vibrations per hour (5.5 vibrations per second).
This is a caliber with a date display added to the Pellaton Caliber 853 which is representative of IWC and has excellent winding efficiency and shock resistance.
Gijsbert L. Bruner a world-famous watch journalist describes Cal.8531 as ``the pinnacle automatic winding watch that Switzerland has brought to the world.''
It is a design that can be said to be a model of an elegant luxury watch with the careful craftsmanship typical of Inter and the atmosphere of the 1950s.
