It is a small but functionally important steel part; if it wears out or breaks, the crown no longer engages cleanly – and precisely such springs are often missing in vintage Seiko movements.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe part fits the Seiko hand-wound calibers \u003cstrong\u003e19A, 1904A, 1920A and 1944A\u003c\/strong\u003e – all members of Seiko's 19-series women's caliber family (1960s\/70s).

The caliber 1944A served here belongs to exactly this Hi-Beat generation and is closely related to caliber 1964A – the \u003cstrong\u003e19GS, the women's Grand Seiko\u003c\/strong\u003e – with which it shares numerous components. A genuine NOS spare part from this family is accordingly sought after.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eDelivered in the original Seiko spare parts bag (green\/white) with printed part no. 386190; enclosed is the older original Seiko box with the handwritten stock identification \"Venus\".
