I did a search of "355" on this forum, and came up empty, even on the Caliber database. I would enjoy hearing comments from Forum members, and of course will update the template with more information if anyone knows who made the case, the movement, etc. I would be interested in knowing what anyone might know about the movement, especially why it seemed to have such a short production run. Maybe Gruen thought the movement was redundant with the introduction of the Curvex?
