This is an all-original 1968 Seiko 6106-8000 measuring 41.5mm in stainless steel. This watch is truly undervalued in my opinion. The dial, hands, crystal, and crown are original. The automatic caliber 6105 movement was just cleaned and is accurate. This is the earlier and rarer ‘proof dial’-version. I don’t need to say much more. Most of these watches are cobbled together with aftermarket parts, making this one very valuable.
