    David Landes. Revolution in Time. Clocks and the making of the modern 
    Cambridge, Mass. Harvard University Press, 1983. p. 231; p. 442.

    It seems like a miniature astrolabe, perhaps with the stars rotating 
    through a watch mechanism (though he doesn't say whether there was any 
    spring-driven mechanism in it). He only references a Dutch advertisement 
    from 1697 for the pocket globe. It seems it's meant as an example of what 
    Adam Smith called "trinkets of frivolous utility"--an early modern example 
    of conspicuous consumption.
