Polished stainless steel case with internal rotating bezel. 
Thin case at only 10mm thick. 

Some scuff marks on outer bezel from normal usage, but otherwise in very good working order (I tried my best to capture signs of usage, but if unsure please take the time to ask to avoid unrealistic expectation).
 
Seen pictured with third-party sailcloth strap purchased to match the colour scheme of the dial. 
Original brown leather strap also included.  

Part of collection that has not seen enough wrist time, hence the sale.

Complete with box and manual.
