Week, date, month ……Gear, correction, power ……In the classical wrist watch, the calendar demonstration complex function’s operation, will affect the time demonstration inevitably accurate. Therefore, accumulates family clock and watch master to be clear, relies on “Dual-Wing” biplane wing cassette mechanism this magic weapon, can realize the perfect work, the making like astronomical observatory table equally accurate calendar wrist watch. On the clear legible refined dial plate, demonstrated that the hour, the minute, the second, the calendar and the phase of the moon, this lets Duomètre à Quantième Lunaire the biplane wing phase of the moon calendar wrist watch, if a section of classical wrist watch. But, under the wrist watch watch case’s 381 cassette mechanisms are partly visible. This section of remarkable cassette mechanism take “Dual-Wing” the biplane wing design as a foundation, has unprecedented accurate, enables the wrist watch to become world high-level scheduling industry the outstanding person. “Dual-Wing” the biplane wing cassette mechanism is the wrist watch design true unusual place, its most major characteristic has two mutual independent power origins: The power which adjust by the escapement mechanism and the balanced balance wheel uses in timing accurate completely, but the second power supply specially uses in the function
demonstrating: Hour, minute, second, calendar and double hemisphere phase of the moon. Flickers jumps the second hand to guarantee two driving mechanism synchronization movement. Duomètre à Quantième the Lunaire biplane wing phase of the moon calendar wrist watch unfolded accumulated the family to study the workshop industrious research and development the crystallization, let the human eye preceding bright: Flickers jumps the second hand by 1/6 second caper advance, lets wrist watch time accurate achieve the crest, simultaneously the calendar and the phase of the moon demonstrated in the independent small dial plate. Through the deep research, considers the scheduling theory basic principle, accumulates the family scheduling expert to rely on “Dual-Wing” the biplane wing cassette mechanism success to make a calendar wrist watch. This principle’s outstanding characteristic has guaranteed the accurate time, but passes, only then does not have any complex function the wrist watch to be able to have this kind of privilege. Only some 178 years specialized experience, Fang Nengrang accumulates the family to open in the high-level scheduling history the brand-new chapter.
