A commonly seen style of fake. Probably something your dad picked up cheaply on a holiday to Marbella or similar in the 70s. Open it up and you鈥檒l find an FHF movement or similar. Unless solid gold, which it won鈥檛 be, other than as a sentimental keepsake, it鈥檚 worthless. Less than worthless actually since it sets out to deceive with bogus markings for both manufacturer and gold content. They still occasionally pop up at boot saies for a couple of quid.
