Seiko V172 minute dial and seconds hand no reset


Scorp

Recommended Posts

Hi All,

I have a Seiko V172 I won at auction, needed a new Solar Capacitor so fitted one and the watch time function is spot on. 

The Chrono however wont recalibrate to reset at 12. With the crown fully out (Position 3), I long press at 2pm or both 2pm and 4pm buttons but all they do is operate the chrono as per normal as if crown was at position 1.

The Alarm function can be adjusted. 

The Minutes Sub Dial wont count when the Chrono sweeps past reset... I'm suspecting that either a minutes gear has stripped or the coil has failed, would a faulty coil affect the ability of the watch to enter the calibration phase? 

Thanks in advance

Scott

Could be that the contact to signal stem position to the IC is not working.

Seems highly likely. Maybe a quick squirt of contact cleaner into those contacts would sort it, or even just pulling the crown out and in a few times. Take care with electrical contact cleaner, you don't want to get some of those solvents on the dial.

    • Does anyone knows what size case a need for a dial diameter 20.60mm?
    • Sounds like the story with my Rolex. Poor (expensive) job done by an official Rolex dealer with an "in-house" watchmaker, hence I learned watchrepair and did the servicing myself. Same story as I learned with the Omega 861, again poor job by an "in-house" watchmaker by an official Omega dealer. Once your watch goes through that back-door, you have no idea what is going to happening to it 🫣   Quite nice that they sent back the parts which had been replaced !
    • yes that's definitely not right at all. I have a picture one of my friends has a Omega coaxial there was having issues to lose asking me where he should send it. As that's a specialty watch I suggested the service center. When he got it back he sent me a picture so the replace the dial as you can see the hands the mainspring barrel and I think the price was really quite decent considering all the stuff they can replace. So I do know they do change the barrels but the other person I worked at the service center when I would ask questions and unfortunately I can't remember all the answers. I think a lot of the changing a parts is at the discretion of the watchmaker. Plus I don't know enough about the chronographs and whether that would be considered a vintage watch? I take some of the vintage watches may have been sent directly to Switzerland or another service center. Obviously with a watch like the one down below they probably have a infinite supply of parts is its relatively modern vintage stuff becomes more interesting even the watch companies don't have necessarily infinite supply of parts. But no matter what the watch shouldn't disintegrated six months that's definitely an issue.        
    • glad it worked out, those ESA movements are obsolete but new old stock is still out there, now that you know the make/model you could also do a cross reference to see if something more current would line up with the dial feet and hands...for future use if needed 👍
    • I wish they would have done so in this case. The whole story went like this: I sent my speedmaster to an omega service center about 10 years ago (at that point of time I haven't even started watchmaking). After the watch came back to me it had only about 6 months wristtime until january 2024 (not fair for this nice watch but the other pieces of my collection want wristtime too 🙂). So my conclusion is that the barrel was already faulty when it came back from service, can't imagine that amount of wear in 6 months wristtime. In january 2024 the performance on the wrist was quite bad, so I decided to have a look by myself. I have to admit that I didn't check the barrel close enough as I thought it must be ok, couldn't have issues after official omega service. That was a mistake, I will learn from that. Follow the golden rule: Nothing is certain except death and taxes.
