I recently acquired a 1991 Seiko 7T32-7G20 from a New Old Stock collection. They were manufactured in 3 versions, black dial and bezel, black dial with silver bezel, dark blue radial sunburst dial with silver bezel, and silver radial sunburst with silver bezel.

The one I managed to get my hands on has the dark blue dial. The case and bracelet are in mint condition, the hands dial and crystal are mint.

It had never been serviced so expected it to not work correctly and also expected battery corrosion.

On opening the case I was pleasantly surprised to see no corrosion at all. But the stopwatch, minute sub dial and alarm were malfunctioning.

I took it apart and on close inspection of the circuit tracks there were a few areas of very slight corrosion, bridging some of the tracks and thus shorting areas of the circuit. I rectified this, it came up like new and passed tests.

After a thorough clean, lubrication and reassembly of the movement, all functions now work correctly.

I'm really chuffed. In this condition from the 1990's they're extremely rare. I think.

Here are some images and a video:
