Description

Introduced in 2015, caliber 3750 is the result of over 8 years of development and consists of over 2800 parts, including 242 jewels and three column wheels. Among its most notable features is its Hebraic Perpetual Calendar that is shown alongside the regular (Gregorian) calendar and business calendar. Due to the long-term changing cycles of the Hebraic calendar and its difference with the Gregorian calendar, its implementation in a watch was considered impossible until the unveiling of caliber 3750. This calendar includes a year indicator and and a Yom Kippur sector.

Other notable features include the double retrograde rattrapante chronograph with two seconds hands moving in sync, yet not with one atop of the other; a night mode for the sonnerie, a chiming alarm, an ISO 8601 business calendar, a triple-axis 'armillary sphere' tourbillon and much more.
