This is re-edition of the LONGINES CHARLES LINDBERGH chronograph with pilots bezel calibrated or determine position while in flight. The 37mm. Stainless steel case is hinged and opens with the lower (right) push pin. Notice the onion winding crown. The white dial appears to be enamel; but, being a newer watch, we are not familiar with its’ construction. The automatic winding LONGINES movement is quite accurate.
