These Oris series of Watches are such good value for collectors and buyers alike.  They are such high quality but come at a reasonable price.

This World Timer has one main dial which you set like a normal watch.  It then moves the smaller sub dial on the right which you set to the time zone in another country.  This Watch is set at NYC time for the sub dial and GMT for the main dial.

The buttons on the left and right of the crown then move the main hour hand forwards or backwards to set the local time.  Very simple to use and easy to read.

The smaller sub dial on the right is then the seconds hand sweeping around.  This watch is hardly worn and in great conditon.  The only sign of wear is the inside of the strap - which you cannot see when worn.  

The dial is a Silver and grey guilloche dial - such lovely detail seen on high end watches.  The Indices and hands have Superluminova C3
