5R86
5R86好像是SEIKO最早的Spring Drive計時機芯的樣子
Servicing for the Seiko and Grand Seiko Spring Drive chronograph movements 5R86 and 9R86 requires the watch to be sent to Japan. These intricate movements contain over 400 parts, and their specialized Tri-Synchro Regulator means they must be serviced by technicians at the Shinshu Watch Studio.
Why the 5R86/9R86 movements must be sent to Japan
Complex Spring Drive technology: Unlike a standard mechanical or quartz movement, the Spring Drive movement relies on a mainspring for power but uses an electronic regulator to control the hands. The unique combination of mechanical, electrical, and electromagnetic power requires specialized training and equipment for maintenance.
Vertical clutch chronograph: The chronograph mechanism on the 9R86 and 5R86 uses a vertical clutch to prevent the second hand from jumping when it starts. This feature requires specific expertise for servicing.
High-end craftsmanship: These movements are hand-assembled by highly skilled watchmakers in Japan. This same team performs the intricate repair and maintenance work.
Recommended service intervals and process
Service interval: Seiko and Grand Seiko recommend a complete service (overhaul) approximately every three to four years to maintain optimal performance.
Service in the US:
Initiate a service request through the official Grand Seiko USA website.
The US service center will handle the shipping logistics for sending the watch to the factory in Japan for repair.
Estimated cost: As of late 2023, the cost for a complete service on a Spring Drive chronograph (9R86/9R96) is listed as $1,320. The price includes a movement overhaul, gaskets, cleaning, and a light polish of the case and band.
Declined estimates: A shipping, handling, and insurance charge is assessed if you decline the repair estimate after evaluation.
2022雪姬US定價6200
2025雪姬US定價6900
我買在日本雪姬調漲前
今年賣掉..全新未戴..還好還能賺點錢
賣的時候雪姬定價應是6500
阿舍/GS近幾年漲得有點誇張
我不會勸人不買spring drive
但是會勸人不要照定價買
至少打7折才能入手
其實我阿舍/GS的SD表大都6折多入手..還都是經銷商入手
就算入手價很優..要轉手還是得賠死
版主真的要保留這支錶
只能後送日本吧?
不然就廉價轉手..讓別人花功夫去整理
因為就算你整理好這支錶轉手也沒價值
我還在等白鋼+SD的GS或是阿舍
