GIRARD-PERREGAUX GP4500
Self-winding mechanical movement

The GP 4500 responds to the continuing trend for large gentleman’s watches and demonstrates GIRARD-PERREGAUX’s strategy to compile a complete portfolio of Manufactory-made movements to equip our growing collection. Some details for the more technically-inclined:

A superior winding efficiency with :
- Central unidirectional winding rotor with oil-free ceramic (zirconium oxyde) ball bearings.
- A coupling and uncoupling clutch featuring a sophisticated arrangement with the ratchet wheel in the centre surrounded by the small planetary gear wheels also oil-free.

The gear train features the original solution of a double third wheel. Thanks to this arrangement, there is no need for a large fourth wheel in the centre, allowing more space for the barrel. At the same time, it provides three ways of displaying the seconds without an additional module.

GIRARD-PERREGAUX GP2700
Self-winding mechanical movement

With the GP2700, GIRARD-PERREGAUX introduces a small, compact movement specifically designed to equip ladies’ watches and respond to the increasing sophistication of the Manufactory’s female clientele.

Some details for the more technically-inclined:

∑ Central uni-directional winding rotor with oil-free ceramic (zirconium oxyde) ball bearings.
∑ The gear train (barrel, centre wheel, third and fourth wheel) features the original solution of a double third wheel. Thanks to this arrangement, there is no need for a large fourth wheel in the centre; this allows more space for the barrel. At the same time, it provides three ways for displaying the seconds without an additional module.
∑ The escape wheel is fitted between combined jewels.
∑ The cross-wise balance bridge allows greater precision in critical tolerances, a solution that reinforces the movement’s accuracy and long-term reliability and makes it considerably easier to adjust.
∑ The fine index adjuster has an original solution with an adjustment screw fixed to the train bridge. This unusual positioning for a more compact construction also allows for easier adjustment and servicing of the movement.

小时／零件数：214

芝柏现代表款的基础
GIRARD-PERREGAUX以钟表原厂的精神为基础，设计一系列能满足现在与未来需求
的自动上炼机芯，包括两种最新成员（GP 2700和GP 4500）。这两种机芯系列是
GIRARD-PERREGAUX现代表款的基础，它们提供各种男女表款的全系列机械机芯，
设计和制造都在GIRARD-PERREGAUX Manufactory内进行。这代表GIRARD-PERREGAUX
钟表原厂文化的具体实现。GIRARD PERREGAUX选择自动上炼机芯是有原因的。
这些机芯代表该品牌对机械表的现代原创性，也是忠于传统和坚持钟表原厂精致机芯
的表征。简单的说，它们提供了我们希望现代表款具备的舒适性，以及数百年的丰富
历史。

GP2700 VS. GP4500
其中，GP2700小型机芯是GIRARD-PERREGAUX针对女表设计的制品，也响应了女
性客户对精致感与日俱增的要求；而GP4500则响应了市场对大型男表的需求，展现
GIRARD-PERREGAUX提供全系列钟表原厂机芯的策略。GP4500机芯和GP2700
机芯的中央单向上炼机制都使用陶瓷（氧化锆）滚珠轴承，而轮系设计非常精致，
棘轮位于中央，周围的小型行星齿轮也不需润滑油。机芯的特殊不对称棘轮设计，
让自动盘单向上炼停止时，可减低其空转的死角至15度（一般单向上炼其空转死角约
为40度），使得上炼机制更为敏锐，即使是小的摆幅动作即可开始上炼，源源不绝的
动力支撑整体机芯运作，更为精准。齿轮组采用独创的双层三番车作法，缩小第四番
车，可以加大发条匣占的空间，而且不需额外模块，就可提供三种显示秒针的方式。

只能说精密
