Omega De Ville Tank XL Ref. 155.006 – Oversized 1972 Icon with Automatic Elegance
A Striking Tank with Mechanical Soul
The Omega De Ville Tank XL Ref. 155.006 is an arresting example of early 1970s design language—angular, architectural, and unapologetically bold. Produced in 1972, this rare reference features an oversized tank-style stainless steel case, measuring an impressive 27 x 50mm. Its sharply faceted edges and elongated rectangular form deliver wrist presence unlike anything else in Omega’s De Ville lineup.
Despite its daring proportions, the watch remains elegant and balanced, with a clean grey dial that enhances legibility and modernist restraint.
Smooth Operator: Automatic Calibre 684
Housed within this sculptural case is Omega’s Calibre 684, a compact automatic movement known for its reliability and slim profile—an ideal engine for dress watches with contemporary flair. With serial number 35294933, this piece confidently dates to 1972.
Recently serviced by our in-house watchmaker, the movement runs flawlessly and is backed by a 12-month mechanical warranty, ready for daily use or careful collecting.
