New member here. Mine is marked 1956 on both movement and case back. Case is WRGP and movement is 3 position adjusted. Dial is black starburst with hour markers like the "F" model but the case design looks like the "H" model. Movement is 23J 10BPAC. I love these old 23J autowind movements. They were extremely durable, reasonably accurate and had a very long power reserve.
