Seiko SKX007J1

The Seiko SKX007J1 stands as one of the most legendary automatic dive watches ever built. As the superior Japan-made “J” variant, it features the highly sought-after “Made in Japan” dial text and refined finishing exclusive to JDM production. Paired here with Seiko’s classic Jubilee-style stainless-steel bracelet, the SKX007J1 provides both authentic tool-watch capability and timeless everyday wearability.

Now discontinued, original J-series SKX models have become cornerstone pieces for Seiko collectors—representing the final generation of ISO-certified Seiko divers before the SKX line was officially retired. The SKX007J1 remains the most recognized and most collected version within the entire SKX family.
