Bovet has a long history in creating multiple time zone timepieces, including world time timepieces, and the Récital 28 Prowess 1 is no different. Not only is it a worldtimer, but it is a worldtimer that also adjusts to Daylight Savings Time, and is the first to do so while incorporating a perpetual calendar and tourbillon. The world time system is comprised of 24 rollers around a central dial, each with four positions - UTC, AST (American Summer Time), EAS (Europe and America Summer Time), and EWT (European Winter Time). Pushing the crown rotates each individual cylinder 90 degrees, so every time zone can be individually set for each of the four time periods of the year. T he brand new movement developed for this timepiece, housed inside Bovet's signature Writing Desk case, incorporates an expanded double-sided flying tourbillon which can be seen at 12 o'clock. As a result of over five years of development, the Récital 28 Prowess 1 represents a significant leap in solving terrestrial timekeeping problems and ensuring accuracy in global timekeeping. Also available in Red Gold and Platinum, this timepiece has a limited production of only eight pieces per year.
