540兄, 小弟已知之前的5065的315有八顆 Gyromax, 但小弟的5065('06/12購入)是315/293機芯,卻是有四顆Gyromax,是315的改良型? ![]() |
應該是
我的5146(315)也是四臂的擺輪

這好玩!得查查是否所有 2007 版 Aquanaut 之 315機芯都是此版本。也就是即將改為 324機芯之「過渡期版本」。
這可能是因為原本想要讓 315機芯 和 324機芯共存,但又不想生產兩種 Gyromax Balance Wheel,所以統一使用和 324機芯一樣之「四臂四顆版」。後來因重疊性太高,乾脆停止 315機芯,直接統一用 324機芯為往後 PP 大三針日期之主力機芯。 以上可能性極高。想當初小弟購入第一代 5060A 時," Aquanaut" 名詞尚未誕生,大家稱之為「輕量版 NAUTILUS」。當時小弟之 5060A 原裝折疊扣上一樣只刻 "NAUTILUS" 字樣,店員也稱之為 「NAUTILUS 橡皮帶版」。後來 Aquanaut 確定要自立門戶時,5065 和 5066 就再也沒有 "NAUTILUS" 字樣了。 還是要恭喜大大們,獲得極少量之 「315 四臂 Gyromax」絕版機芯! ![]() P.S. 以下看出「四臂 Gyromax」的確是 28,800HZ 之 324 才開始使用的。沒想到連 21,600HZ 之 315 末代版也「偷用」了。 ---------------------------------------------------------------------------------- The calibre 324/205 is a new automatic movement (4 Hertz, 28,800 vibrations per hour) that was created based on a complete remodelling of an earlier automatic calibre. The goal of this re-make is to offer better amplitude stability and greater working precision. To this end, the gear train has been recalculated in order to minimize gearing effects. But, in increasing the frequency, the power reserve decreases. So, the oscillating weight has been resized, enlarged and made thicker in order to produce more energy. The Gyromax balance (a Patek Philippe patent from 1948 and 1951) has been entirely redesigned. The two arms and eight movable inertia-blocks have been replaced by four arms with four regulating inertia-blocks integrated aerodynamically . With the same objective of optimizing the constant of energy distributed, a new shape of the gear teeth has been developed. All the pivots of the gear train axes have been revisited in order to avoid all wear and tear. Many other details, all contributing to the reliability and life span of the movement, have been reassessed. The minute-hand bar has been constructed in two parts, the date gear train is asymmetrical and the thickness of the winding gear train has been strengthened. ---------------------------------------------------------------------------------- _________________ 「蛛絲馬跡皆學問,落花流水皆文章。」 |

嗯,那要再推到 324機芯推出後的同期 315機芯,甚至有可能是 "Rolex Daytona 4130 Parachrom 事件" 的翻版,新機芯324未發表前就已經先「偷跑」了... ![]() _________________ 「蛛絲馬跡皆學問,落花流水皆文章。」 |

(1) 用於28,800HZ脈動的擺輪,套在 21,600HZ脈動用,穩定度和壽命理論上都會改善。 (2) 四顆當然比八顆好調整,維修技術性也減半。 (3) 站在生產成本的角度來說,四顆 Gyromax 也比八顆成本低,畢竟 Gyromax 是高精準的微型部品,也是 PP 當年的主力賣點。 (4) 以「工藝」角度,也會有人批評 PP 正在降低其工藝性。 言歸正傳,該「末代 315 機芯」(如果確定停產),數量的確比傳統 315少;使用該絕版機芯的 Aquanaut 5165 、5167,因只發行一季,又更加稀有。買到的人,恭喜吧! _________________ 「蛛絲馬跡皆學問,落花流水皆文章。」 |

![]() 不過重點是歐洲那些投機客是秉持物以稀為貴原則去收購,反正價位又不高。這才叫「投機」...。想當初 5060A 也因為限量 1000 支炒得好熱,其實也只差後來之 5066 一個非透明底蓋而已...。
