Today I have a vintage Concord Mariner SG (Stainless Steel & 18k gold). The model number is 1578115. This is an incredibly thin (approximately 6mm) integrated bracelet sports watch, containing an ETA quartz movement. I am downsizing the collection and looking to sell. The movement is running well. The condition is shown in the photos, with minor scratches present on the bracelet and case. The crystal is in good condition. The case diameter is approximately 35mm case diameter but wears larger with a lug-to-lug measurement of around 45-46mm. This will come with 4 extra links and screws which would fit up to a 7-inch wrist. The bracelet has a missing screw near the case, which was assessed by a watchmaker and had locktite applied. This does not affect wearability and is only visible from the underside of the bracelet.

Given the condition of this watch, asking $275 F&F (+3% G&S depending on reputation) shipped CONUS. Please PM with any offers/questions/concerns. Please reply here before sending PM, as per the guidelines set by the subreddit. This watch is keeping excellent time, with cosmetic condition in above photographs (am happy to send additional photos on request). Please refer to my reputation and ask for additional information if required. Have an excellent day!
