Masterpiece CollectionSBGZ009Hand-engraved Manual-winding Spring Drive Limited Edition
以隆冬時節的壯麗白樺林景象為靈感，雕金 Spring Drive。
銀色錶盤與950鉑金錶殼呈現了這片森林的自然之美。專業製錶師、雕刻師與工匠創造的這款工藝腕錶是完全由自家內部精細打造的完美成果。首先透過超鏡面研磨技術在每個錶殼營造完美無瑕的鏡面效果，然後再經由與Micro Artist Studio位於同一廠房的信州時之匠工房中的熟練雕刻師在每個錶殼上精心手工雕刻細長的個別溝紋，營造出和錶盤相同圖案並完美呼應了生動白樺樹海景象。
A majestic white birch forest comes to life on the case, echoing the pattern of the dial.
Skilled artisans with expertise in advanced jewelry techniques have crafted a masterpiece inspired by a white birch forest. Its fully hand-engraved Platinum 950 case is harmoniously complemented by the white birch dial.
A dial with carved text and markings.
The white birch dial is further refined through elaborate carvings for the Grand Seiko logo, Spring Drive, the mark at 6 o’clock (denoting gold applied markers), and the minute track.
The hour and minute hands, as well as the indexes, are crafted from 14k white gold. The seconds hand is tempered to a shade of grey that harmonizes with the dial and has an appearance that stands apart from that of coating or plating.
An impressive 84 hours of power reserve for a slender Spring Drive wristwatch.
The Spring Drive Caliber 9R02 was designed by the team at the Micro Artist Studio. Its Dual Spring Barrel technology combines with the Torque Return System to achieve a power reserve of 84 hours (3.5 days) while allowing the watch to maintain a slim form.
