The 9025A Crystron LC is similar to the 9021A Crystron Alarm Calibre but it uses a sub-loaded PCB without the Alarm driver components and functionality. Has slim display segments and green tinted display. The green tint in these early Crytrons is from the actual front polariser and not from an additional filter as in the yellow display of the Seiko 0624. Strap is original to the watch.
