Blancpain Fifty Fathoms Trilogy limited edition 18K rose gold automatic diver's watch, number 51 of only 100 produced, reference 2200-3630, featuring a black dial with luminous markers, rose gold Arabic numeral rotating bezel, Calibre 1151 with 100-hour power reserve, date between 4 and 5 o'clock, and dark brown leather strap with contrast stitching. 40mm case, 13mm thickness.

Complete with box and papers.

The Fifty Fathoms Trilogy Edition's most visually distinctive feature is its large-format unidirectional rotating rose gold bezel with cut-out Arabic numerals at five-minute intervals — a bold, architectural detail that gives the watch an almost sculptural presence well beyond what its 40mm diameter suggests. The black dial is clean and functionally pure, with luminous Arabic numerals at the cardinal positions and luminous baton markers between them, all in rose gold tone that creates a warm, cohesive color palette across the entire dial. Calibre 1151's 100-hour power reserve is an exceptional technical achievement that places this watch in a distinct category among luxury sport watches — most automatic movements offer approximately 40–48 hours, making this movement's reserve more than double the industry standard and providing practical utility that collectors immediately appreciate.

The Blancpain Fifty Fathoms holds one of the most significant positions in watch history — widely recognized as the world's first modern diver's watch, created in 1953 for the French Navy commandos and establishing the design standards that every dive watch produced since has followed. Blancpain, founded in Villeret, Switzerland in 1735 as the world's oldest watch brand in continuous production, has maintained the Fifty Fathoms as its flagship collection for over seven decades, always in precious metal or high-grade steel and always powered by in-house movements of exceptional quality. The Trilogy Edition — produced in three precious metals as a unified collector's set — represents the most exclusive and commemorative expression of the Fifty Fathoms ever offered, with each metal variant limited to 100 pieces worldwide. Number 51 of 100 in 18K rose gold, complete with original box and papers, is a fully documented, fully traceable example of one of the most historically significant and collectible limited edition dive watches ever produced. This is not merely a luxury watch — it is a piece of horological history with complete provenance.
