All modern compatible watches from Casio are made of plastic: black or chromed plastic. Only some vintage models are in real metal. Vintage watches that came with modules 451, 587, 590 or 595 (maybe more) will also fit a module 593, but you'd still have to source a module 593 for its plastic chassis and other parts. Also, just the other week there popped up a steel replacement case for sale on AliExpress, which as been confirmed to work fine.
I bought a vintage Casio W-34 (Module 590) just for my Sensor Watch because I wanted one of steel and because it resembled my broken A158W that I had used for years.
