That's a good reference to start with. The dials are hard to fake or redo. You'd want to make sure the movement is correct. It should be cal.751 given the dial and the chronometer designation. I don't know if there's a specific range of movement numbers for these, but I've seen them in the 29m or so up to 32m.
Try to get some more pics, including inside of caseback and the movement. Also, if you care to, share the price.
