Seiko AGS Scuba SBBW015 [5M23-6B40]

A recent acquisition is this min condition Seiko AGS (automatic generating system), which is an innovation on the movement that Seiko introduced sometime in 1988. This later became well-known as their Kinetic line of watches with AGS being retained for Japan domestic models (i.e., Kinetics were for international release models). I have one other AGS, which is my Landmaster Titanium and a Kinetic auto-relay that has a lot of sentimental value.

Dial showing the immaculate bezel, blue face, Kanji day and date features. Also visible is the power reserve guide that allows one to check how much power remains with the press of the button at 2 o'clock.
Side view showing what appears as raised hour indices. The lumes on this watch is also in great condition.

The bracelet is original and luckily is a good fit to my wrist.
The case back showing the watch the details on the watch including the serial number indicating this to be made in Japan in March 1994. That makes this watch to be more than 24 years old.
The watch on my wrist the first time I tried it on.

The capacitor on this watch was already spent and it didn't function long after taking the watch off so I had it checked. The newer capacitors were not cheap and there was the option to use a battery instead so I had it converted into a regular quartz watch but with the indicator still functioning. I intend to have it back as an AGS/Kinetic in the future. Here's the interior with the battery fitted where the capacitor was. Perhaps Seiko already thought of this as a back-up to when the capacitors cannot be replaced?

I took this photo of the movement and the battery in place of the capacitor
