Journe Tourbillon Souverain Vertical was introduced in 2019 to commemorate the 20th anniversary of the original Tourbillon Souverain. This reference remains in current production and features a 42mm platinum case housing the manual-wind caliber 1519. Unlike traditional horizontal tourbillons, this movement utilizes a vertical tourbillon cage that rotates every 30 seconds to maintain constant rate performance regardless of whether the watch is placed flat or on its side. The dial is constructed from 18k rose gold with \"Clous de Paris\" guilloché, featuring a power reserve indicator at 12 o'clock and a small seconds sub-dial. Collectors value this reference for its technical departure from the standard Souverain layout and its high-frequency rotation. On the secondary market, these timepieces typically trade in the mid-to-high six-figure range, often between $450,000 and $600,000 depending on provenance and condition."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "fpj-tourbillon-souverain-souscription", "brand": "F.P.
