Selling my Seiko 6138-0030 Blue Kakume from June 1976. Just received a full service that included case polishing, movement service, and pressure test. So, it’s keeping good time and all function work well and resets to zero. Note, I have not timed the watch to a known time source. It’s been on my winder since service. The watch seems to be all original, but I do not know the history prior to getting it a few months ago. The bracelet is sized for around 7.24-7.5” with two extra links. Also including the blue NATO strap that’s pictured.

Quick update. Another member informed me the bezel POSSIBLY doesn't check out as original based on the gold tachymeter font. I've had a few of these in the past that I've had restored, some with aftermarket parts. I'll never try to hide anything, but I am no expert. So I greatly appreciate the insight from fellow members.
