Two original softcover promotional sales catalog books issued by Breitling, highlighting their signature aviation and diving timepieces under the emblem "Instruments for Professionals". The catalogs feature high-quality glossy color photography, model histories, technical movement specifications, and brand visuals. Featured timepieces inside include model series such as the Galactic Chronograph II and the Superocean 44.

Both catalogs are presented in good vintage condition. Subtle creasing along the covers and spine margins. Interior pages remain clean, fully intact, and vibrant with no significant tears or markings observed.
