SEIKO GS GRAND SEIKO SPRING DRIVE GMT watch SBGE001

" The Legend lives On"

USED condition

DESCRIPTION :

This is an one (1) Pc Authentic SEIKO GS GRAND SEIKO SPRING DRIVE GMT watch SBGE001

Spring Drive is the summit of watchmaking mechatronics achieved by SEIKO's technology and heritage, and hand assembly is done by our most skilled craftsmen in Japan.

The genius of Spring Drive

Long power reserve : 72 hours Fast winding : approximately 30% improved compared to the most traditional mechanical winding system. High accuracy : Equivalent to ± 1 second/day Glide motion hands : the only watch whose hands' motion reflects the true nature of time The Glide Motion of hands

All the motions in the movement are one-direction. Spring Drive hands move smoothly, quietly and evenly across the dial.

The Glide Motion reflects the real nature of the time.

Mechanism of Spring Drive

How it works

Source of energy: The sole motive power is the main spring. Transmission: The power of the mainspring is trans mitted via gear train to the hands and to the Tri-synchro regulator. Regulation: The Tri-synchro regulator controls the speed of the glide wheel and the hands by electromagnetic braking.

Spring Drive 的設計是基於機械機芯,Tri-synchro Regulator 就像 傳統擒蹤 運作。 於 1977年,一位工程師於日本的 SEIKO EPSON's Suwa plant 構想出 Spring Drive。 3項 新設計 促成了 Spring Drive Tri-synchro regulator 發條 Magic Lever

Tri-synchro regulator (紅圈) 取代了 擒蹤 - 傳統手錶最脆弱的部份 Tri-synchro regulator 的 3個主要部份: 石英震盪器 - 產生 頻率 積體電路 - 憑 頻率計算 時間 及 控制 電流通過 電磁圈 Glide Wheel - 由 電磁圈 控制,它把 Tri-synchro regulator 及 傳統的傳動輪組 接上,並且每秒轉 8 圈。

發條 全新的 發條 是由一種高彈性物料 (Spron 510) 所製成,它可產生更大的能量。結果是 發條可輸出 更多、更順 和 更持久 的能量 -- Spring Drive 最長可運行 72小時。

Spron 510 是 Seiko Instruments Inc. 的 註冊商標

石英震盪器 及 積體電路 需要的電源是由 電磁圈 產生。發條 釋出能量,透過 傳動輪組,再由 電磁圈 轉化成電能。

Magic Lever -- 自動上鍊

Magic Lever 系統可有效地把 擺陀的動能傳到 發條。此新設計提升了 30% 的上鍊效率。

用同一能量來源 - 配戴者之活動 用同一能量儲存方式 - 發條 用同一方式傳遞能量 - 傳動輪組 唯一分別是 "時間之源" 及 控制部份 - Tri-synchro regulator 此新概念帶給我們高度準確的時間顯示 --- ±1秒 / 日 Grand Seiko: -3 +5 sec / day

C.O.S.C.: -4 +6 sec / day

石英:±1 sec / day

C.O.S.C. 石英:±0.07 sec

原子鐘:0.000000001 sec / day
