g shock regulation

[dr. d]

ahoy folks.
i have question.
i have a vintage casio digi-ana g-shock (from back when they were still cased in stainless steel).
it has always run fast, i.e., more than one minute a month faster (that's 60 seconds or more a month, much faster than its factory-rated 15 seconds a month).
i am wondering, can it be regulated?

It is model specific I think. Some models could have a screw trimmer capacitor adjustment to regulate the timing.

Best if you can determine the model number and look it up. If it does have an adjustment screw, best have it done at an authorized service center. They may have the necessary equipment to do the calibration more accurately. Also, they will also likely check for or replace other serviceable parts like O-rings and whatnots to maintain its water resistance rating.... given its age.

I looked and looked and looked some more.... can't seem to find any specific information that this model has the trimmer adjustment.

neither did i.
i was hoping, someone out there would have some personal experience regulating it.

timegraphers are common -enough equipment among watch fans in the youtube, but as this casio is a quartz... and an ancient model at that...
it may be big and bulky and somewhat heavy, but it's design is so nice, it fits my wrist so nicely... my perfect travel watch. waterproof to 200m, quartz-accurate, time-zone-capable, chronograph (medyo button-y lang), and very shock resistant.
