Opinions On A Possible Broken Daytona

[Furrygoat]

Recently I came home from work and noticed my Daytona was somehow running 5 min slow. The watch seemed like it was running normally otherwise, so I just thought maybe it was a low power reserve issue since that morning when I picked it up it had been sitting (running) for a day or two.

Similar situation last night in that the watch had been sitting unworn for a day or two but still running. I put it on for the evening and wore it overnight. I also had the chronograph running overnight for approx 6.5 hours.

This morning the watch was 2 hours slow.

Is this an issue that could be chalked up to low power reserve in combination with use of the chrono, or is it more likely a more serious issue?

The watch is still under warranty so it’s an option to send it in, I just wonder if I need to go through all of that.

Thoughts appreciated, thanks in advance.

If it was a Seiko, I'd suggest it's a stuck hairspring or something like that, and to give it a firm tap with your knuckle on the case back.

Since it's not, and it's under warranty - I'd take it in.

Even with a low power reserve and running the chrono it shouldn't slow down by 2 hours. Take it in, especially if it's under warranty.

I’d start by giving it a full wind and wear it for a few days in a row and see how far behind it is after 3-4 days. There’s a chance that the power reserve is so low that it is stopping, but as you toss in your sleep it is enough to get ticking again for a little while. Start there and if the problem continues send it in.

Well most all cases like yours its down to owner error on there part,I would give your watch a full manual wind 60 plus full crown turns clockwise only.Then after a full manual wind wear it for 8 hours plus a day, and check time over a few days,if watch keeps good time all is well, if not it needs service.

I was thinking along the same lines.

The question remains. If it works normally when fully wound/throughout the majority of the power reserve (which I think it will), is it normal for it to behave like this when closer to discharge? Or should it behave normally all the way up until just stopping?

Could be balancing at the very tail end of the reserve. Just barely keeping going, but not with enough juice to keep proper time.

The advice in this thread about winding and wearing is sound. Report back once done to let us know the outcome

I’m with Padi on this. Assuming your watch is a modern 4130 movement, it works best when worn regularly. I generally rotate days between my Daytona and BLRO, both with 70 hour reserves, they both keep very accurate time. If I let either sit too long in between wearings I will need to wind them up and reset before using again. I’ve never understood the rationale of running the chrono just to run it, but of course that is accelerating the power drain on the watch too. I would wind it fully and wear for a few days straight to check before sending it off.

Will do thanks.

And I was timing my sleep! It’s a very important data point. I wasn’t just running it just to run it

[Tools]

Wind it.. You are not active enough and it is stopping periodically from lack of power.

[P1nky_Up]

Check this thread out. Gives a good example of how the watch slows as power reserve gets low.

Somewhat bad news (I think) as I got home around 10 hours later and the watch is still running strong about the same amount of time behind that it was when I left this morning.

Given that there was still at least ~15% power reserve left it seems more unlikely that it was an effect of the tail end of the mainspring.

Still gonna do some monitoring.

There’s no way you can really know how much power reserve was left. If you let it sit all day then wear it in bed when you’re sedentary strange things will happen. Just wear the watch during the day! It honestly doesn’t sound like anything is wrong.

[jimcameron]

Manual wind, then wear it. Report back.

[ThatSubGuy]

Did you ride your bike/motorcycle with it? Did you run with it on? Bump it against anything? Sounds like a spring issue.

[garyk]

Sounds like a lot of people agree, wind it, wear it, and it will probably get back to normal. Some people are not active enough to keep their automatic watches wound...

[Alan111]

Follow all of the tips here in winding and wearing.

If it is losing time when the Chrono is running, try resetting the Chrono and not letting it run. If it does not lose time, then this is an issue I've seen on here before. It will need to be taken in.

[Furrygoat]

Thanks for all of the input. It’s been about 18 hours since I’ve fully wound it and it’s dead on accurate +-0.

I’ve run the Chrono for a few hours here and there to try to induce change. Nothing so far.

So I suppose I’ll chalk it up to normal that it runs a heavy deviation with more than 10 hours left in the power reserve?

i.e. I woke up at 0500 and noticed a large deviation. Happened previously to 0500 (obviously).

Left watch in drawer expecting it to expel power reserve. Came home at 1500 and watch was still running.

I guess at the end of the day I can just have it put on a timeographer.

Exactly what I was going to say (you said it more concisely).

[GoingPlaces]

I had a reserve issue with my Daytona. It wouldn't lose time, just stop. Even with a full wind and and no chrono running I was able to eke out about 36 hours if I set it down. I took it in, they did something to it and now I have about 72 hours reserve. Daytona's have lots going on in there. Chrono's are complicated, take it in.
