Omega Seamaster 600 Ref. 135.012 – Mid-Century Elegance in Gold

A refined classic from the golden era of Omega, the Seamaster 600 Ref. 135.012 represents the brand’s mastery of understated design and reliable mechanics. Produced in the mid-1960s, this model blends timeless proportions with quiet luxury, offering a versatile dress watch with enduring appeal.

Design & Heritage – Omega’s Elegant Simplicity

Introduced during a period when Omega was cementing its reputation as both a tool-watch innovator and a producer of elegant dress timepieces, the Seamaster 600 exemplifies the maison’s dedication to balance and clarity. At 33 mm, the gold-plated case offers restrained vintage proportions—perfect for collectors who appreciate mid-century subtlety over modern excess.

The silver dial remains spotless and original, bearing Omega’s classic applied logo and minimalist indices that exude sophistication. Complemented by its original Omega crown and framed under period-correct plexiglass, the watch radiates authentic 1960s character.

Technical Details – Caliber 601 Precision

Inside beats the Omega caliber 601, a manual-wind movement that has just undergone a fresh service and is keeping excellent time. Known for its robust design and reliability, the cal. 601 was widely celebrated in its era and continues to deliver smooth winding and strong accuracy today. Its serial number 22066081 dates production to circa 1965, firmly situating this piece within Omega’s vintage golden age.
