SEIKO Quartz "SQ" Sports 150 (NOS)
Caliber 5Y23-6050 One jewel
Screw in crown 150m water resist
I have been starting in my collection in early discontinued Seiko quartz watches that were fully manufactured in Japan. This 5Y23 is one brilliant new-old-stock with complete papers and hangtags. The fine details of the raised "SEIKO" and "SQ" add to the elegance of this otherwise rugged sports watch. The gold-plate is of matt finish and cancels away the bling-bling commonly found in gold-plated watches. This Seiko somewhat gave me a "Tag-Heuer" look and feel to it if you recall the early Tag-Heuer Professional 200 series. As of early Seiko quartz, hitting spot-on the markers is a for-granted.
Look closely at the movement and you will notice the wordings "ONE (1) JEWEL JAPAN". You will never ever see this description in newly produced Seiko quartz watches!
