A question, how common is the late 1960's Super Polerouter, I've seen one or two advertised one with a 17j micro motor unit and a 2nd with the 28j unit. Both had 20mm lugs and Rolex style screw down crowns fitted, so were bigger than the early 215 and its immediate relatives, any views

 

This is a picture of a Polerouter chronometer, I've not seen the case and unfortunately I lost the auction, again does anyone know anything about this, unusual movement and the case it came in

 

I've only ever seen the Polerouter Super with the cal. 69 that is also found in some Polerouter dates. No idea about the case regarding the cal. 215-9 but referring to polerouter.de, this calibre shouldn't have a date but an increased frequency 21 600/hour and 28 jewels.

 

this super polerouter was up for sale maybe 6 months back with a £1,500 asking price, I do like the tuxedo style but as it was a 17j movement I thought it too expensive, but still a very stylish watch
