This is a beautiful vintage Concord Mariner (Ref. 15 78 115). Concord was one of the kings of the quartz crisis and was a leading luxury swiss brand at the time. This is a watch from the golden years. Very high quality and a lot of bang for the buck. Polo vibes without the polo price tag. This finishing on this watch is incredible. The polished recesses in the bracelet grab a lot of light and the brushed case and bracelet even it out to be just right. 32mm case (wears larger due to the integrated bracelet being 22mm at the lugs) 5.5mm thin! Will fit a 7.25 inch wrist Solid 18k gold bezel, inner bracelet links, and logo on clasp (not plated). Has developed some very lovely patina. Includes original outer box and instruction manual Give me this over a PRX any day. ***Priced at $425 shipped CONUS*** Payment via Zelle or PayPal Happy to answer any questions or provide any additional pictures!
