Audemars Piguet Royal Oak Tantalum - Tropical Dial (Ref. 56175TT), 1990s

Dealer description — Huntington Company

History and Significance The Royal Oak Ref. 56175TT was introduced in the early 1990s to mark Sir Nick Faldo’s back-to-back major championships in 1990, at both the Masters Tournament and The Open Championship. This watch is significant for being the first Royal Oak produced in a two-metal combination of tantalum and stainless steel. Tantalum, with its distinctive blue-grey hue and durability, lends the case and integrated bracelet a subtle visual depth and tactile difference. With a 33 mm diameter case and ultra-slim profile enabled by the quartz calibre 2612, the 56175TT captures the Royal Oak’s design DNA — the iconic octagonal bezel with visible screws and integrated bracelet — in a compact and refined form. The case-back features a “Championship” engraving linking it directly to Faldo’s achievement and to Audemars Piguet’s early connection with sport sponsorship. For collector's, the combination of rarity (limited to approximately 2,000 pieces) and material innovation places the 56175TT in a unique position in Royal Oak history. Writer’s Thoughts Despite its modest size, the 3796D wears with quiet authority. Its balanced proportions, crisp hobnail bezel, and Gübelin signature give it both historical significance and subtle charm. Our Promise Every watch is thoroughly vetted, carefully described with complete transparency, and guaranteed authentic. Each piece is offered in honest condition, ensuring collectors receive a timepiece that reflects both originality and integrity.
