This 1969 Seiko M88 Sealion houses the precise reference 6106B 25 jewel automatic movement in a timelessly classic gold 6106-8030 case that just oozes vintage design. We love any Seiko from 1969 as it marks the year Seiko debuted the quartz wristwatch that rocked the watch industry the world over! This one came into Chrono Collector in decent condition (we've definitely seen worse) but was filthy and not running. We lovingly serviced, cleaned, and lubricated this watch, and it should be good to go for years to come. The bezel and crystal were replaced with OEM Seiko factory parts (see pics). With minimal regulation, this powerhouse 6106B movement comes in at around +3seconds/day dial-up on the timegrapher!
