补一句，现代O最佳机芯是1120，这是无数血泪教训买回来的教训
1120-2500-8500这一路升级的核心推动力，更多 ...
先不管是否量产，ROLEX和PP都在登记新的擒纵专利干嘛？纯噱头？如果在物理理论上，锚式杠杆擒纵已经完美，他们仅用物理公式证明即可，何必再费劲设计新擒纵？
转爱表AP版主algtrd的发言：
由同轴引起的新擒纵革命（内含惊人新发现！）
最近看了chn6兄发表的8500和同轴擒纵的技术贴，很受鼓舞。我对技术是一瓶子不满半瓶子晃荡，对O和同轴也接触不多，唯一喜欢做的就是在google上搜索资料学习。偶然地搜索到了许多在同轴之后的各类新擒纵的资料，和大家分享，特别是希望chn6这样的专家能够消化吸收以后再为大家科普。从这些资料里我看到在近几年里各大厂家对新擒纵的研发普遍加速，而且是八仙过海各显神通。唯一的解释是这些厂家的研发部都通过同轴擒纵看到了新技术的优势，唯恐落后于人。从这个侧面，我认为纵使2500有过缺陷，哪怕8500不能把新技术的优势全面发挥出来，总体上O还是指出了技术发展的大方向。
0. 从同轴说起，它的各项关键技术之一是直接传动（direct impulse）。在摆轮一来一回的过程中，同轴把两次传动中的一次变成了直接传动。而各类新擒纵也都在直接传动上做文章，所以我在google上搜的是“direct impulse escapement”。
1. AP的新擒纵是O的同轴以后的第一个投入生产的。它和同轴的设计很不同，摆轮一来一回只有一次直接传动，另一次是空摆。这个擒纵用在AP非常高端的一些机芯里，还没有达到量产规模。这里的新消息是AP开始对外提供新技术了，Richard Mille的RM031就用了AP新擒纵：http://www.greatreporter.com/con ... her-novelties-20122
2. 早期对同轴的同行技术分析指出一个不足是只有一半的传动变成直接的。有人指出过，如果用两个同步的摆轮，就可以把所有传动都变成直接的。但是这个技术超难。如果说有哪家厂能够做出这双摆轮的擒纵，恐怕非FP Journe莫属，因为他做的Chronometre a Resonance（共振机芯）就用了两个摆轮。果然，FPJ的最新款式，Chronometre Optimum，就用了两个摆轮的双轴全直接传动擒纵：http://www.watchtime.com/wristwa ... hronometre-optimum/
3. 同轴的发明人George Daniels最初是想把技术转让给PP的，被PP高傲地回绝了。PP在看到O使用同轴技术以后，又在看到老对手AP做了新擒纵之后，有没有后悔过当初的选择？或者有没有坚持自创技术的路线，但对新擒纵技术重新看待？英语论坛PuristsPro上一位表友找到了PP在美国专利局登记的新擒纵设计，也是直接传动的。虽说还没有上市的表款（PP的保守是有目共睹的），但是立场肯定是动摇了：http://patek.watchprosite.com/?show=nblog.post&ti=432676
4. 这个是惊人的发现：R也在美国专利局登记了直接传动的新擒纵设计！是去年1月！当然，也只是一个专利。不过，5、6年前，我在隔壁论坛参与一个R版讨论R为什么不做复杂表款的时候，搜索到了R在美国专利局登记年历机芯设计的资料，当时R版的回复认为专利归专利，R还是会坚持走简单路线。当然我们现在等到了天行者。这个专利会不会在不久的将来带给我们R的新擒纵机芯？它的技术和O的同轴相比如何？我们拭目以待: http://www.highbeam.com/doc/1P3-2555746511.html

兄弟应该把这个消息再发劳坛，无论如何都是超有价值的信息啊，看看这次大家的预言都如何。
这里有些： http://www.google.com/patents/US80878196 L# [- M2 _2 I
看附件里的图好像和AP的擒纵有点像。文件里还提到了2006年一个宝玑的专利设计。越来越有趣了。
This escapement comprises a balance wheel (3), an escape wheel (1), a detent rocker (4) having an arresting element (4a) and an elastic clearance element (4c), means for inserting the arresting element into the path of the teeth of the escape wheel (1), and a clearance pin (7) rotating integrally with the balance wheel (3) in order to engage with the elastic clearance element (4c) of the rocker (4) once per period of oscillation of the balance wheel. The means for inserting the arresting element (4a) into the path of the teeth of the escape wheel (1) comprise a sliding surface (4b) integral with the detent rocker (4) and arranged so as to move into the path of the teeth of the escape wheel (1) when the arresting element (4a) leaves it, this sliding surface being shaped so as to return the arresting element (4a) to the locking position.

Claims
1. Direct-impulse escapement, especially of detent type, for a horological movement, comprising:
a balance wheel attached to an impulse element,
an escape wheel whose teeth intersect the path of the impulse element,
a detent rocker having an arresting element and a clearance element,
means for inserting the arresting element into the path of the teeth of the escape wheel,
a clearance pin rotating integrally with the balance wheel, and
means for engaging said clearance pin (7,11d) with the clearance element of the rocker once per period of oscillation of the rocker to clear the arresting element from the escape wheel tooth;
said means for inserting the arresting element into the path of the teeth of the escape wheel comprising a sliding surface integral with the detent rocker and arranged so as to move into the path of the teeth of the escape wheel when the arresting element leaves it,
this sliding surface being shaped so that the force applied to it by a tooth of the escape wheel causes the arresting element of the detent rocker to move back into the path of the teeth of the escape wheel
the arresting element of the detent rocker comprising a safety surface situated outside of the path of the teeth of the escape wheel (1) and adjacent to this path when the detent rocker is in the unlocking position, in order to prevent the arresting element (4) from moving into the path of the teeth of the escape wheel while the latter is communicating a movement impulse to the balance wheel.
2. Escapement according to claim 1, in which the length of the safety surface corresponds to the angle travelled by the escape wheel to communicate the movement impulse to the balance wheel, in order to prevent the premature return of the arresting element into the path of the teeth of the escape wheel.
3. Escapement according to claim 1, in which said clearance element is pressed elastically against a stop, so that it behaves like a rigid element when said clearance pin meets it while rotating in one direction and moves away elastically when the disengagement pin meets it while rotating in the other direction.
4. Escapement according to claim 1, in which said clearance pin is integral with an inertial member mounted freely between two extreme positions, in one of which the path of the clearance pin passes by said clearance element of the rocker, and in the other of which this path does not pass by this clearance element, the passage of the inertial member from one position to the other resulting from the inertial force acting on the inertial member due to the variations of speed of the balance wheel during each half-cycle of oscillation of the balance wheel.
5. Escapement according to claim 2, in which said clearance element is pressed elastically against a stop, so that it behaves like a rigid element when said clearance pin meets it while rotating in one direction and moves away elastically when the disengagement pin meets it while rotating in the other direction.
6. Escapement according to claim 2, in which said clearance pin is integral with an inertial member mounted freely between two extreme positions, in one of which the path of the clearance pin passes by said clearance element of the rocker, and in the other of which this path does not pass by this clearance element, the passage of the inertial member from one position to the other resulting from the inertial force acting on the inertial member due to the variations of speed of the balance wheel during each half-cycle of oscillation of the balance wheel.
