I have here 2 very nice examples of the Prim Sport II. These 2 have the nickname "Humberto" due to the colourful dials The plastic friction bezel is bidirectional. Both watches are equipped with the Prim inhouse cal. 68, a true work horse.. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&an0&2uswk&Prim_68_4 Both are in very good condition and all parts are original Prim parts. Bezels are new, the old ones were missing (as often the case with these). The only flaws are marks on the case and pitting on the underside as the cases are chrome plated of course. Both watches have undergone service just a few days ago by my watchmaker. Now the best part! These really fun vintage sports watches can be yours for 225 EUR / piece Postage will depend on location. Payment via Transferwise or Paypal. Any questions, just ask. BR, Jan
