Combining a flying tourbillon with a retrograde date display that resets at month's end, the Portuguese Tourbillon Mystère Rétrograde tracks its seven-day power reserve via the IWC 51900 calibre. Commemorating the 75th anniversary of the Portugieser family, this luxury update includes an arched-edge glass, improved ergonomic lugs, and a Santoni alligator leather strap. The sapphire-glass case back reveals a solid red gold rotor and blued screws within the movement.
