The post-war Omega Jumbo reference 2505-6, with its remarkable 38.5 mm case, stands out as a significant piece from the late 1940s. This size was notably larger than the average watch dimensions of its time, making it a unique find for collectors. The watch houses Omega's esteemed caliber 265, part of the celebrated 30mm series, known for its precision and durability. With a manual movement featuring 15 jewels, this timepiece exemplifies Omega's engineering excellence.

The dial has been professionally restored by a dial specialist using period-correct techniques, appealing to those who appreciate vintage charm with enhanced legibility. Maintaining authenticity, the watch features a period-correct acrylic crystal and a signed crown. These elements, along with its clean case lines and elegant lugs, reflect the transitional design sensibilities of the late 1940s, a time when wristwatch aesthetics were evolving.

This particular reference, 2505-6, is a less common variant, increasing its desirability among collectors. The movement's serial number, 1170xxxx, places its production circa 1947, verified from internal movement serial tables, marking it as an early post-war creation. Its combination of size and movement pedigree makes it a sought-after piece, especially for those who value both functionality and sophistication.
