They share the same caliber, Genta's design, and the blue horizontal-embossed dial, but represent two distinct moments of the same family: the 5711/1A is the steel reference Patek Philippe discontinued in 2021, and the 5811/1G is the one that took its place in catalog that same year — in white gold, not steel.
