This is a very fine circa 1968 Tudor Submariner 7021-0 blue dial and bezel known as the ‘Snowflake’ due to the dial layout. This dial is completely original and not pitted like most examples, notice the red date. The hands are original with only the hour hand (matching) re-lumed. This blue bezel and dot are original. The 40mm stainless steel case looks fantastic; and like most, was likely polished at some time, but not brutally. The original automatic Tudor movement was serviced within the past two years and is accurate. 7399xx is the serial # with the case back being original and dated 1968. The #7 has faded from bracelet wear but is evident. The crown screws down but will likely need a new one in the future, which is easily available. This is an honest and amazing-looking vintage Tudor Snowflake.
