These “ladder” bracelets, as they are known, had ZENITH stamped on the outside of the buckle. On the inside, BREVETE GF STEELINOX SWISS MADE, and the quarter of bracelet production, with quarter shown as one digit above the year shown as 2 digits, is stamped. “GF” was shown with as the Gay Freres logo, with an image of a ram’s head between “G” and “F”. The quarter of bracelet production did not necessarily coincide with that of the A386 case production. Watches with a Gay Freres bracelet were delivered in a cylindrical box.
