Catalogue description

Dealer description — Craft & Tailored

The Tudor “Snowflake” is the nickname given to the Tudor Submariners with distinctive features such as the square hour markers and a unique snowflake hands that were introduced by Rolex/Tudor to increase visibility in low light conditions. In production from 1968 to the mid-1980s, dial variants are commonly found in black and blue and can feature a date complication. However, there is more to the Tudor’s Snowflake Submariner line than its characteristic visual features. The Tudor Snowflake Submariners, 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). Marine Nationale Diver Wearing Turdor Submariner "Snowflake"7016/0 The second-generation Tudor Submariners marked the watchmaker’s transition from caliber 390 movements produced by Parmigiani Fleurier SA (Fleurier) to movements produced by Swiss watchmaker ETA which made the Tudor Snowflake Submariners the first Tudor watches to use these modified ETA movements. This specific example would make a nice addition to a growing collection or be a great first piece as it retains the classic and timeless look of the Submariner while being unique and eye-catching as a result of the distinguishing dial and hand configuration. Stock # TDRSUB739411/0-2 Brand Tudor Style Submariner Model 94110/0 Serial 79XXXX Size Men's Material SS Dial Blue "Confetti" Millimeters 40 Bracelet Handmade Leather Strap CASE & BRACELET The previously polished case retains nice thick and even lugs. The watch retains the original Rolex signed trip-lock crown. The original "fat font" bezel insert has taken on a light grey fade showing some patina from use with the original pearl remaining intact. The case back engravings are clear and remain clear and visible. The watch will be supplied with handmade leather strap. DIAL & HANDS The Black matte "snowflake" dial is in wonderful vintage condition. The matte portion of the dial itself has taken on an interesting velvety textured patina; sometimes referred to as a confetti dial due to the fact that the matte dial consists of flecks of blue, green, grey, and black that make up the base color of the dial. There is some degradation on the right side of the dial by the rehaut that can be seen when looking at the side of the dial at a slight angle. The lume plots have taken on a charming ivory patina. The lume plots when viewed under U.V. light show no lume loss or degradation. The original "snowflake" hands have been restored professionally by Los Angeles Watch Works using tritium to match the coloration of the lume plots on the dial. ACCESSORIES None. The watch is keeping time at spec but extended service history is unknown.

Historical context

Quartz Revolution (1969 – 1990)

Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.

Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

Atlas type guide

Dive and water-resistant watches

Keeping water and dust out of a wristwatch was a long-standing challenge. Rolex's screw-down Oyster case (1926) and Omega's Marine (1932) were landmarks; in the early 1950s Blancpain's Fifty Fathoms and Rolex's Submariner defined the professional dive watch with rotating bezels for timing dives, luminous dials and high water resistance. The ISO 6425 standard (1982) later codified what a 'diver's watch' must do.

Dive watches became icons of post-war design and exploration, and their evolution — helium escape valves, ceramic bezels, saturation-diving depth ratings — records the history of underwater work.

What to look for

  • Unidirectional or bidirectional rotating bezel with minute markings.
  • Screw-down crown and case back; depth rating printed on the dial.
  • Luminous hands and markers (radium before c. 1960, tritium c. 1960–1998, then Super-LumiNova).
  • Reference numbers on the case between the lugs or inside the back.

Dating clues

  • Screw-down Oyster cases: from 1926.
  • Professional dive watches: from 1953.
  • Tritium 'T' marks on dials: c. 1960–1998.
