Summary

The video walks through Bvlgari’s latest Octo Finissimo release, contrasting the newly sized 37 mm model with the established 40 mm version and highlighting the engineering tweaks that differentiate the two.

While the case diameter shrinks, the overall thickness rises modestly to 6.45 mm from the previous 5.15 mm, preserving the collection’s ultra‑thin reputation. More striking is the movement: its thickness grows from 2.23 mm to 2.35 mm, yet the power reserve jumps from 60 to 72 hours—a 20 % gain.
