Beta 21 in a Steel IWC International Case
IWC Steel Beta 21 International
- Time (Hour, Minute, Central Second)
This is a well preserved example of the most relevant quartz watch of all time -- Beta21 movement housed in a IWC steel case with integrated bracelet.
The watch is impressive on the wrist even when worn in this steel version, because of the sweep second, the humming (instead of a ticking), the size and its historical relevance.
By the way: This is one of the earliest examples of IWC Beta21 movements we have ever seen and was definitely sold in 1970.
