The journey of a watch enthusiast into the past, present and future of Seiko. 🇮🇹🇯🇵
Back in the late ’70s, Seiko introduced the Slim Back in the late ’70s, Seiko introduced the Slim Turtle divers with a brand-new case design that quickly became an icon for the Japanese brand. The “Slim Case” went on to feature in many dive watch series before becoming the go-to standard for the 5 Sports line starting in 2019. But over time, this case design also popped up in some lesser-known models that many seem to have forgotten—like these three gems right here. From left to right: the Seiko Alpinist SARB063 (limited to 500 pieces), the Subaru limited edition (360 pieces), and the WENA Premium Black (300 pieces). #seiko #seikoskx #seikoslimturtle #seikoslimcase #seiko5sports #seikodiver #seikowatches #seikoalpinist

Where are Seiko watches made? https://www.theseiko Where are Seiko watches made? https://www.theseikoguy.com/where-are-seiko-watches-made/ (link also in bio) The production dynamics in watchmaking, both in Japan and elsewhere, are highly complex and have been a topic of considerable debate, particularly since it became common practice for companies to shift part of their manufacturing to countries with lower costs. In this article, I’ll delve into where and how Seiko Group watches are produced, and I’ll explain the differences between “Made in Japan” models and those that aren’t.

It has been five years since I became passionate a It has been five years since I became passionate about Seiko watches and the long history of this Japanese brand. Beyond the watches I collect, there is another aspect that is just as important to me: researching information and, in particular, documenting the past. This is part of my Seiko library, which includes, from top to bottom: - Old and new books about the brand, its history, and the history of the Hattori family; - Over half a century of annual catalogs (the collection is nearly complete, with only a few volumes missing); - Decades of “Seiko News” volumes, which provided monthly updates on new releases for Japanese retailers. In addition to all this, I have gathered dozens of internal publications, price lists, and vintage product catalogs, along with a vast collection of technical documents on watches and movements. Much of this material is extremely rare and difficult to find. Assembling it all has been a long journey, but these resources are invaluable for understanding both the past and present of Seiko and Japanese watchmaking. #seiko #seikowatches #japanesewatches #grandseiko #seikosha #kingseiko #vintageseiko
