I'd say Justin's figure is close to where you'd expect it to be. The quartz versions don't come up often and although yours has normal signs of wear and tear it would still be in demand. I'd possibly put less on for the bracelet, but would think $1800-2000 with bracelet would be about right.....however you could indeed get more of someone really wants it.

Your watch has all the hallmarks of a monnin, with the 24h dial, cathedral hands, case back design and stamping and the bezel has no inner metal ring (tramline) around the glass as seen on later non-Monnin models.

Great looking watch and hope you get many more years of use out of it.
