Specifications: I can't say I know too much about this brand, but I purchased it while hunting down watches with this case (Sinn 8820, Squale 1553, etc). The case was made by MRP SA (patent number 503.305). Here is the listing I originally purchased it from. He has more information on the watch, and also includes some pics of the open caseback and quartz movement - [https://www.watchuseek.com/threads/g%C3%A9rard-vintage-diver-80%E2%80%99s-patent-mrp-s-a-20-atmos-eu-seller.5572808/](https://www.watchuseek.com/threads/g%C3%A9rard-vintage-diver-80%E2%80%99s-patent-mrp-s-a-20-atmos-eu-seller.5572808/) Condition: pretty good considering its age, worn sparingly since purchase - see photographs for an accurate representation.
