Omega Ladymatic 1966 — First impression - 11031-1

The Omega Ladymatic Ref. 11031-1 embodies mid-1960s Swiss elegance in a compact 22 mm case. Its softly rounded stainless-steel body frames a clean ivory dial with applied hour markers and slender hands, achieving perfect legibility despite the small diameter. The domed acrylic crystal enhances the watch’s vintage warmth, while the automatic Cal. 455 offers mechanical convenience without sacrificing slimness. This reference represents Omega’s pioneering commitment to producing reliable, fully automatic movements for women’s watches—an important milestone in horological history.

Omega Ladymatic — Ivory Dial

The dial is a smooth eggshell tone with a subtle satin finish, signed “Ladymatic” in elegant script above 6 o’clock and “SWISS MADE” discreetly below. Applied faceted baton markers reflect light at changing angles, while the absence of a date window keeps the layout balanced and understated.

Ladymatic 11031-1 — Hands

The dauphine-style hour and minute hands, paired with a polished central seconds, provide excellent contrast against the light dial. Their dark finish ensures clarity even in low light, underscoring Omega’s attention to detail in functional design.

Omega Ladymatic 11031-1 — Polished Stainless-Steel Case

The round case features straight lugs and a narrow polished bezel that maximizes dial opening. Measuring 22 mm in diameter and 28 mm lug-to-lug, it sits gracefully on the wrist without appearing diminutive. The domed acrylic crystal adds period-correct charm and is easily replaceable if ever required.

Ladymatic 11031-1 — Crown

The original Omega-signed fluted crown is slightly oversized for easy operation, ensuring smooth hand-winding and precise time-setting. Its condition and crisp logo confirm originality.

Omega Ladymatic — Leather Strap

The watch is fitted with a brown pebble-grain leather strap that complements the dial tone. Though a quality replacement, it remains true to the style of the era and secures comfortably with a tang buckle.
