From 6pm to 6am, the wheel features a luminous green radium (the illumination is no longer). From 6am to 6pm, the wheel switches to black. \u003c\/p\u003e\n\u003cp\u003eThe radium on the dial has patina'd the white dial, and it looks striking. The day\/night wheel is in great condition with no apparent damage or wear, despite the lume no longer luming. \u003c\/p\u003e\n\u003cp\u003eThis watch features a high dome crystal, and measures about 34mm without the crown.
