This circa 1957 Omega Seamaster Calendar in stainless steel remains all original and unpolished. The 34mm case with beefy lugs does not have any major dings. The caliber 503 automatic winding movement was just cleaned and is accurately keeping time. This dial and hands are all original including the deep vanilla lume. This winding crown is correct and likely original. Fewer of these calendar watches were produced compared the the time only Seamasters. You will love it!
