[Seiko Crown J15003E] A glimpse of Grand Seiko before Grand Seiko
One of my recent vintage Seiko pickups — a Seiko Crown J15003E from around late 1950s.
The dial is what really got me. It has this unusual split-concentric or "record groove" finish, with incredibly fine circular lines that change from silver to almost charcoal depending on the light. Add the long applied markers and dauphine hands and it feels very distinctly late-1950s/early-1960s.
Inside is Seiko's 21-jewel hand-wound Cal. 560. The Crown itself is an important part of Seiko history: introduced in 1959, it became the technical basis for the first Grand Seiko released in 1960.
At 36.5mm with 19mm lugs, it also wears beautifully. Probably one of my favourite examples of early Seiko doing a lot with a very simple design.
