Switzerland made this precision instrument was sold by O. Zernickow Co. from New York.
Complete original set with instructions, in it's excellent condition storage case.
Appears to be functionning properly... upon push of button, 6 second chronometer starts and hands rotate when wheel is turned.

Unable to test for accuracy.

Excellent condition, no owner identificatin markings

I'm assuming that these instruments were manufactured in Switzerland then labeled and sold by others such as H.H.Sticht Co., N. Zivy & Cie.S.A., and Hasler
