Seiko 7A34-7000: The ugly duckling…

I am feeding my latest passion of Seiko watches from the 80’s as much as my bank account allows me, which is very little, to be honest, focusing my attention on 7A38 and 7A34 models, since I like them most. Nevertheless, as soon as I saw this particular watch, which is a Seiko 7T32-6A50, I immediately hit the “buy” button. Price was low, so was the word count on the description, stating only that it was not working.

Seiko 7T32-6A50

These are the conditions in which the watch arrived.

  • the crystal is heavily scratched/cracked
  • the attachment lower left slug for the band is apparently damaged/bent
  • the band itself appears somewhat stretched/”tired”
  • all pushers are stuck
  • the two crowns are heavily worn out, with the gold plating completely missing/scratched away
  • the arms apparently move freely, but some force is needed to turn the crown – probably some oil is needed
  • the date wheel moves freely
  • the clasp does not close perfectly
  • the gold plating on one side of the band is worn out in the middle
  • the whole watch is completely dirty and full of debris on every band link and around the pushers and crowns, around the crystal bezel and the back cover

After a quick “clean up”, I disassembled the Seiko 7T32-6A50, and these are the various pictures I took of the operation:


The serial number of this watch is  202206, and being a 7T32 series, the useful quide that can be found here: Seiko 7A28 / 7A38 / 7A48 / 7Axx Simple Do-it-Yourself Production Date Calculator, unfortunately cannot be used, since that is only valid for watches produced until 1990.

I did find another link on the internet:

Following the scheme of ideas, and considering that, as stated there, Seiko manufactured the 7T32 series from 1988 to 2002, using the dating system linked before would eventually result in two possible manufacturing dates: October 1992 and October 2002. It can be either month/year combination, but it has to be one of them. But which?

The dirt and the damages to the crystal and to the slug of the case are clearly visible in the pictures. In one of the next posts I will show the result of a perfect clean and the initial fixes I did to the slug.

I did however a small research on the parts I need to replace, and came up with this small list:

  • 300WF4HN01-GLASS
  • U7T3226-MOVEMENT (?)

The last one, the movement, I am not quite sure if I need to look for a replacement. I will first try to fix everything else, and if nothing works, I will try to buy a new or used working movement from another Seiko 7T32-6A50.

    I inherited a 7T32 6A50 from my father & it is a loved part of my 35 watch collection. Unfortunately, the main crown stem has come loose & obtaining a replacement appears to be next to impossible. The watch still works at the moment but I’d love to return it to it’s former full glory.

    Hello George. I have a 5T52 World Timer Sports 150 that I’ve been holding onto fro years after obtaining it from an online seller for a small price. It was not working at that time and I thought a new battery would do it. However, a watch repair shop near me said the movement was dead. I’ve been looking for a replacement movement from a donor watch. Is that the best way to proceed? Cheers!

    • Hi Kevin, that is the fastest and probably cheapest way to proceed, provided you find a donor watch that is banged up, but with a working movement… I would still try to fix it, if I were you. These do not come cheap nowadays… Let me know if you need help!
