We can only tell you so much with only one photograph to go on. But, based on this one picture, the dial looks original and the leaf hands are correct for the no-radium dial. Collectors sometimes refer to this dial as a "shy-10" dial. The subsecond hand also looks OK, and the chrome case looks correct from this view. The "fab.suisse" suggests the intended market for this watch was France.
The crown has likely been replaced several times over the watch's life, but the bowler crown that is there now is of the correct type for the period. Based on the fixed lugs and the style of the dial I'd guess the watch dates to the late 1930s. Inside should the venerable in-house caliber 27. All in all, a well-worn watch that wears the scars of a lifetime proudly and is still quite serviceable as a timepiece.
