The one on the left is not on the original bracelet, unfortunately. It was sold with the other SBCZ005 and came on a leather strap. I’ve put it on an OEM Seiko titanium bracelet. If it wasn’t next to the other two, I don’t think most people would realise. If anyone has a lead on a new or used OEM bracelet for it (Seiko p/n D0S0DM) for a sensible price, I’d be very interested! The champagne one uses a 5M43 movement, the other two are 5M63, so they are all Kinetic (or AGS as it used to be called), and all of them hold a full charge. I love Kinetic watches and have several others.

Never seen these before; JDM only?

Always had a soft spot for the way Seiko do their divers though. Thanks for posting
