A showcasing of unique or strictly limited edition pieces, the Special Editions collection by Armin Strom will delight even the most meticulous of aficionados. Named after the natural elements of Earth, Air, Fire and Water, The Tourbillon Royal Flush is a timepiece with double spring barrels, a 10-day power reserve, off centre time indication, a trademark of the Strom house, and a barrel bridge which is hand engraved with the Royal Flush combination. The casing is made of 18kt rose gold, while the case back has anti-reflective treatment. The dial ring is black with founded appliques, which makes a striking contrast with the rose gold hands and bezel. Another timepiece in the collection limited to four pieces only is the Coffret Tourbillon in white gold and the Tourbillon Earth (Coffret) in stainless steel PVD black.
