Submersible QuarantaQuattro
The 44mm case size ("quarantaquattro" is Italian for forty-four), introduced at Watches & Wonders 2022 to sit between the 42mm and 47mm Submersibles. Runs the slim ValFleurier-based automatic Calibre P.900 (4.2mm thick, 3-day reserve) rather than the 42mm's in-house P.9000, keeping the case thinner.
