    My latest HAQ acquisition: a vintage Seiko Twin quartz 9726-8000 from 1981

    Hello everyone,
    this is a very brief review if my latest HAQ ebay fishing. Bought it as non working for a decent price, it was really a gamble on my side. And when it came to my house it was REALLY not working. At all.

    It's a 9726-8000, an export model featuring a thermocompensated twin quartz movement, day and date (English/English) and the hour hand adjustable for tracking different time zones without hacking the movement, hence the nickname "Trans Zone Syncroniser".

    The case, the bracelet and the clasp are in fully original condition, never polished and totally unmolested. The bracelet has even all the extra links. I also have an original SQ box and a warranty unused instruction manual.

    The charcoal dial is really amazing, with applied Seiko and SQ logos and indices. The day and date wheel and also the hands are in near prefect condition.

    The watch underwent a full overhaul, that included a total dismantle of the movement and cleaning of all the electrical parts; there was rust inside and some acid leaked from the battery.

    After that all the functions are perfect, the hour hand adjusts independently from the movement, the date quickset and the hacking work as they should. The day doesn't have a quickset function.

    And what about the timekeeping? Originally this was a 20spy watch, more than 30 years ago. Now it's much BETTER! After a week of testing it ran an incredible +0,15 sec / week.

    It's now my everyday watch, with its perfect size for my small wrist, its amazingly comfortable bracelet and the fantastic accuracy. Here is a wrist shot.

    B E A U T I F U L !!

    And a nice performer too!
    Sometimes I really wonder what happened to many of the 80s designs. They hold up 100% even today.

    Waw!
    SEIKO HAQ + day/date + time zone function! This is one great watch, enjoy it!

    P.S.: I wish SEIKO offered a modern day/date + time zone HAQ. While I understand that it won't be a 9F GS, I would imagine a Dolce or Credor with a day/date + time zone, based on a new 8J calibre.

    Very interesting, I'd never heard of a TQ with an adjustable hour hand.

    Nice work on getting up and running again, you're lucky the electronics were not shot. Did you do the work yourself or did yo have someone do it? Can't imagine there are too many people willing to work on vintage quartz watches...

    As for timekeeping, 0.15 for one week is great and clearly a great match for your wearing pattern but with a different pattern (like at room temperature) you'd likely see a significant variation, I do on my TQ that was refitted with a NOS movement last year, around 20spy between Warm and Room if memory serves, which is still very good.

    Congratulations. Maybe it is some Seiko styles that are timeless?

    Thanks everyone for your kind words. And no, I did not service the watch by myself. I will continue tracking the accuracy of the watch during the next months and report back every once in a while if there's any interest.
