The Octo Finissimo Perpetual Calendar is the latest addition to BVLGARI's ultra-thin watch collection. For the first time, the model is presented in a monochromatic blue finish, featuring a 40-millimetre sandblasted titanium case with a blue PVD coating.

The case measures 5.80 millimetres thick and is paired with a blue varnished dial displaying hours, minutes, retrograde date, day, month, and leap year indications. Grey rhodium-plated hands, silvered indices, and a polished steel crown with a black ceramic insert complete the exterior. A blue alligator leather strap secures the watch to the wrist.

The watch is powered by the BVL 305 automatic manufacture movement, which measures 2.75 millimetres thick and operates at 21,600 vibrations per hour. The calibre provides a 60-hour power reserve and can be viewed through the transparent case back. Water resistance is rated to 3 ATM.
