Tudor 7021/0 Submariner Snowflake SS Black Dial c. 1971

The Tudor Submariner 7021/0, introduced circa 1970, is a hallmark of the brand’s dive watch legacy and marks the debut of the iconic Snowflake handset—now synonymous with Tudor’s vintage identity. This reference is powered by the robust automatic caliber 2484, providing reliable performance under demanding conditions. Collectors prize the 7021/0 not only for its striking black dial with square hour indices but also for its technical lineage linking it closely to its Rolex Submariner cousins, yet distinguished by Tudor’s idiosyncratic design cues. With a substantial 40mm case diameter and a 47mm lug-to-lug span, it wears with a pronounced presence, while the 200-meter (20 ATM) depth rating upholds its professional diver credentials. The reference features the early plexiglass crystal and was originally paired with both Oyster-style and Tudor-signed bracelets, as well as tropical rubber straps. The 7021/0 is considered groundbreaking for introducing the date complication to Tudor Submariners, visible at 3 o’clock with a distinctive magnifier. Its enduring desirability is underscored by its rarity and pivotal place in Tudor's storied past—a true centerpiece for serious collectors seeking authentic vintage tool watches. Excellent condition with Tudor box.
