A Tudor Submariner with square crown guards is an extraordinary rarity that could take a lifetime to find - but finding one with a tropical dial is nothing less than a miracle. Manufactured in 1959, this Tudor Submariner 7928 features the first crown guard system introduced by Rolex - a square design, a feature unique to that year before the transition to the more common pointed crown guards in 1960.
This watch is further distinguished by the harmonious tropicalisation of its glossy gilt dial. The balance and integrity of each component are astounding, making this timepiece a piece of frozen history.
Some watches seem to defy the passage of time, their unique character shaped serendipitously by the decades. Such is the case with this extraordinary Tudor Submariner 7928.
