Seiko - 計時碼錶 - 没有保留价 - 6139-8020 - 男士 - 1974

This watch features a rare square case design (often referred to as the Monaco style in collectors), making it significantly less common and thus more easily identifiable and collectible.

这款手表采用罕见的方形表壳设计（收藏家中常称为“蒙地卡罗风格”），因而更为罕见，更易辨识与收藏。

The movement is a core member of the automatic chronograph technology wave of 1969, renowned for its vertical clutch and column wheel structure, and is still considered a representative work of Seiko mechanical chronographs.

机芯是1969年自动计时技术潮流的核心成员，以竖直离合器与柱轮结构著称，至今仍被视为精工机械计时码表的代表性作品。
