A cool neo-vintage (2000) airing and one of the coolest configurations with the engine turned bezel...looks great and allows it wear larger. Don't be fooled by its 34mm case, it wears close to what I remember my old 36mm DateJust wearing. Comes on Rolex Oyster bracelet but looks great on anything I have put on it. The M designation means indicates Rolex moved away from cal 3000 to into the cal 3130 that added a few more jewels and full balance bridge, etc. Service history unknown however running strong Watch and OEM Oyster only No trades, please - strictly in fund raising at the moment Asking $3400 OBO
