Discovering My Grail Seiko: First-Ever Service(?) on a Single-Owner Kakume

In this video, I have the privilege of working on a Seiko 6138-0030 Kakume from June 1975, belonging to an acquaintance of mine. This incredible single-owner watch might be receiving its first-ever service since it left the factory nearly 50 years ago! As I carefully open it up and assess its original condition, I can't help but admire this untouched vintage beauty. After having this watch on my bench, I’ve found a new grail piece to add to my own collection.

The skill required to disassemble and reassemble is impressive. The minutia of key details for this particular watch. The minute recording wheel issue, seconds hand notches note, testing for clearance of the hammer spring and rotor....man

Some of the best close-up photography, and careful editing, that I have seen. Perfect narration too. Ace 👍

The tool you are using to pick up the shock spring is called a Jewel Picker. I just bought one based on Alex's video as well. I have seen some of the min recording wheel gears come loose on these 6138s. Seems to afflict 6138s only for some reason and not 6139s. Not super common but I have seen it enough to always check these on disassembly to make sure that gear is not rocking or loose on the pinion. Nice save.

Wow. Thanks for all the detail, your videos have given me the confidence to start my first chronograph service… I picked up a Seiko 6139 “Darth Vader” from 1977, and will DEFINITELY have your recent 6139 video on standby for the rebuild! Beautiful watch, consider yourself lucky to have been likely the first to ever crack that beauty open. Another fantastic video, thanks Adam!

You’ve done a fabulous job there to get it working so well especially for a 50 year old watch 👍. Also goes to show just how good Seiko designs used to be.

You call your channel "Weekend Watch Repair". If I had that one on the table to repair mine channel would be called "Annual Watch Repair ." You sir are more than an hobbyist, nicely done. I just could not memorize all those plates, levers and springs on that chrono werk. This one went smoothly, I see you've done this a couple of times😅 but I would be sweating over this one being someone's family loom.

Yay! I've been wanting to see this video! Getting a cold beer and heading to my comfy chair...

[fenman]

Not normally a fan of chronograph watches but that is a beautiful watch.

[WristwatchMedic]

I love the watch. You did a great job on it. I have never worked on a chronograph. I have a watchmaker phobia of them .lol Thanks Adam for the video

Old Seiko company really have many genuine cool styles watch. Now they just rehash design without the feature that make them iconic (Progue color speedtimer, seiko time sonar inspired seiko 5).
