Omega Seamaster "Radium Prototype"

Introduced in 1948 to celebrate Omega’s centenary, the Seamaster line was born from the brand’s ambition to create a waterproof, elegant wristwatch suitable for both professional and everyday use. The early Seamaster models, inspired by the robust timepieces Omega supplied to the British military during WWII, combined precision with understated refinement—an ethos that would define the collection for decades.

This Omega Seamaster Ref. 2846, produced in 1958, represents a fascinating early chapter in that story. Featuring the automatic Calibre 501, one of Omega’s most reliable mid-century movements, this particular example—serial number 15.xxx.xxx—belongs to the transitional era that bridged vintage charm with technical innovation. The 34.5 mm stainless steel case remains in exceptionally sharp condition, with well-defined edges and original factory geometry, a rare sight on pieces of this age.

The dial, perfectly preserved, exhibits a subtle vintage warmth and crisp print that testify to its originality. Believed to be a radio prototype, it stands as a remarkable collector’s piece within the Seamaster lineage, merging historical intrigue with mechanical excellence.

Completing the ensemble is a black pigskin LTF strap paired with the original Omega steel buckle, adding both authenticity and elegance. This Seamaster 2846 is a true time capsule from the golden age of Swiss watchmaking—an untouched survivor that captures the spirit of Omega’s pioneering craftsmanship in the 1950s.
