The date of the first flight of the Potez 37 is not known but test flights, flown by
Lemoine, were under way by June 1930. Lemoine and Duroyon continued development flying until at least the end of July. They reported agreeable and straightforward handling characteristics.

The Potez 37 had fixed, conventional landing gear, with mainwheels, equipped with brakes, placed 3.0 m (9 ft 10 in) apart at the ends of half-axles and drag struts hinged to the fuselage. The wheels had near-vertical
