Here's an usual piece:
Coming from Rolex, here is a 1950's 18K yellow gold moonphase watch, model number 6062. This is truly a unique time piece, and this appears to be a stellar example of it. Here is what Aaron Faber had to say about it:
Rolex model 6062, 18K yellow gold case 36 mm with screwdown crown, circa 1950's, silver dial with applied yellow gold faceted dart-indexes with luminous dots, subsidiary seconds, outer graduation for the days of the month in black Arabic numerals, apertures for the days of the week, month and moonphases, black ostrich band with yellow gold tang buckle, automatic 19 jewel movement, condition is very good.
