Rare cal. 77 with probus scarfusia is it one of 600pcs?

Hi guys,

I bought this nice cal. 77 marked Probus Scarfusia and there should be only 600pcs of this piece. Am I right?

Great watch and photos, thanks for sharing.

But I have no details about the limitation.

Usually many different cases were used over many decades.

What is your source for that limitation hint ?

Regards

Hi Hebe,

yes it is here: www.iwcpocketwatch.com/watches/calibre-77/

There is written that: Only 10,500 examples of this “finger bridge” movement were produced between 1917 and 1921. Most of these were made for the U.S. market. Watch produced in Schaffhausen, is indicated by the “Probus Scafusia” stamp on the inside case back (not shown here). It is rumored that only about 600 Calibre 77 watches were cased in Switzerland, with most or all of the others being cased in the United States.
