1972 Tudor "Snowflake" Submariner (Ref. 7021/0) Black Dial

Vintage Tudor Snowflake Advertisement

The Tudor “Snowflake” is the nickname given to the Tudor Submariners that have distinct features like square hour markers and a unique handset where the hour hand resembles a snowflake, hence the nickname. This dial and hand configuration was introduced by Rolex/Tudor to increase visibility in low-light conditions. The Tudor Snowflakes were in production from 1968 to the mid-1980s and were produced with either black or blue dial colorations. The Snowflakes were also made with or without a date complication.

The Tudor Snowflake Submariners, much like the other Submariners produced by Rolex and Tudor, have a long-standing history and were supplied to military forces including the U.S. Navy and the Marine Nationale (French Navy)

The superb case retains extremely thick and symmetrical lugs that display minimal signs of previous polishing and only light signs of honest use. The bezel insert is an early service replacement with a tritium pearl that has aged to a creamy patina, the bezel itself remains deep black with almost no signs of use present. The case retains its original Rolex 7mm twin-lock crown. The original Rolex 7836 folded-link Oyster bracelet with 380 end pieces retains 11 links that show minimal stretch and will fit up to a 7 1/4-inch wrist.


The matte black "snowflake" dial is beautifully preserved and in near-perfect condition, showing no damage and elements of age that are nominal in nature. The tritium lume plots remain bright, with a subtle eggshell coloration, and display no degradation when inspected under U.V. light. The original tritium hands have aged a shade more yellow than the dial, matching closer to the pearl of the bezel insert, under U.V. light inspection the hour hand features very minor surface cracking that is common in "snowflake" hands, and the minute hand remains fully intact and the second's hand is an early tritium service unit that is more white in color. 


None. The watch was recently serviced and is keeping time perfectly, backed by a 1-year warranty on accurate timekeeping.
