Vintage Omega Seamaster Calendar on BOR 2849-6SC - 34mm - 1958 + Box

This 1958 Omega Seamaster Calendar is a stunning vintage piece with a beautifully aged white dial featuring light patina speckling. The dial layout with golden hour markers, Omega logo, date window, and hands contrast elegantly with the black font, crosshair, and minute markers.

Its gold-plated case remains in excellent condition, as does the uncommon, well-preserved gold-plated beads-of-rice bracelet—quite uncommon since most are overpolished. Inside, the Omega caliber 503 automatic movement, overhauled in March 2025, runs smoothly.

Complete with its original box, this Seamaster is a remarkable find for any vintage Omega enthusiast.
