I'm not familiar with that particular movement, but on many movements, 1 full rotation of the crown produces between 1 and 2 hours of power reserve. 5 day power reserve = 120 hrs = 60-120 full rotations of the crown.

 

I know it’s bit of a PITA but I’d wind it as they suggest for a while and see if the problem goes away. At the least you know for sure if your problem is caused by a poor power reserve or something else.

 

If it didn't do it before you had it serviced, then I would send it back to get checked. My experience with service and warranty with nicer companies like JLC and GO was very hit or miss. Second or third time is a charm! 😣

 

See if it corrects itself within a week or so of constant wear. If not, send it back to get it fixed.

Good luck.

 

Doesn't sound right to me... if the low PR (low torque) prevents the date wheel from completely snapped to the next date, it should stop the movement. It does sound very strange that the movement keeps going but the date is not completely snapped. My guess is that you will likely have to take it back to the Service Center to have them checked over. Might be just a very easy fix.

Which Service Center did you send you FF to, and did you go through an AD or directly drop it off at the SC? I'm planning to have my BP serviced, and wonder if I should physically drop it off at the West Coast service center (it's a one-hour drive for me, and not sure if it's worth it... but I feel safer this way than going through an AD).

 

Hi, I went through the NYC boutique. Sounded like there was a watch smith on site. Literally one watch smith on site. There was no talk of sending the watch to a service center from there, only delays in waiting for parts to arrive. Hope that helps!

 

I just don't think I would accept "play with it" on a watch or servicing of this cost. Regardless of why it's acting this way it's not right and I doubt the service was $50. They should be obliged to fix it, and rather quickly.

 

So if your power reserve is on the low side around midnight it will not fully change?
Doesn't sound right to me.

 

While not in the same caliber of movements (pretty close for sure though), I had a Casio MRW-200 that did that. In fact that day/date set up in those seems prone to either the day or the date hanging half way through its travel.

Like I said, basically the level of finish and refinement.

 

Anyway, easy answer is to send it back but would like to avoid that (Blancpain is great but quite slow) if anyone has any insights or similar experiences.

If it didn't do it before, and its doing it now, send it back and have them sort it out.

 

Get it serviced. Does not sound right to me.
If you noticed now, then it did not happen before sending it in.

 

If you never had this before, and since the service was performed this is happening, it sounds as if someone didn't put it back together correctly... Definitely send it back to be fixed for free..

This reminds me of when I had the front end bearings replaced on my Seat Cupra, the garage gave me back the car and it pulled heavily to the right, in other words the idiots did not correct the geometry after dismantling the front end. I call them and they tried to blame me saying "you must have driven into a curb". I had to argue with them to get them to fix it.

 

I had a similar issue on a brand new Omega Seamaster SMP300 right out of the box. I also thought perhaps it was a power reserve issue, or maybe just a sticky spot of lubrication, but after cycling the date wheel through a few times and ensuring full winds and all it continued to do the same thing. I swapped it out, as to me that was definitely not acceptable at any price point to say nothing of $5k for an Omega or much more for a Blancpain.

If it were me, I'd cycle the date wheel a few times, ensure full charges, and see if that did the trick. If not, I'd take it back. And even if it would only work properly on a full charge, I'd still take it back.

We should expect even an inexpensive department store watch to have a working date function. Higher end watches should really ensure QC on this kind of thing imho.

Good luck, and in any case congrats on an amazing watch! Exactly that Blancpain on a bracelet like you've got it is on my long-term grail list. Hope it works out well for you!

 

I had the same problem, even took it back for servicing within warranty. Still happened occasionally, but I was somehow too lazy to go through the whole procedure again, so whenever the date wheel got stuck I just tapped hard the crystal with my knuckle to get it to flip through. You could try this too (and also that I don’t feel alone in this haha).

In the end, I really do think that in this movement if the power reserve is not high enough, the date wheel has a higher chance of not clicking over. The problem went away when I wore it every day. Perhaps the date change mechanism also needs time to break in.

 

Even if the date change over isn't instant at midnight, you would have thought it would complete within a few hours. Does it change over if you advance the time through midnight manually? What about if you reset the date by a few day, in case there is a glitch? Set the time to 11:30 and just see what happens.

 

@BruFlick what ended up happening

 

Sent it back to the NYC boutique who sent it to to the NA service center. Quick turnaround around, good as new now.

Someone earlier in this thread (forget who, apologies) noted to be wary of boutique vs service center work, so that was def a good call out.

 

Hi, I got my FF 5150 back from a full service at Blancpain and now the date periodically does not fully click over in the date window, but rather sits in limbo between the previous and current date.
I’ve spoken to Blancpain and they say it is a power reserve issue.

I know this is an old post but it just blows my mind that they would say this.

Either they are full of crap, or they make embarrassingly bad movements that need high power reserve to do a date change.

 

This has nothing to do with power reserve, he just talked to a customer service rep, who tried to avoid admitting they did a crappy job, and came up with the Power reserve "explanation", to the best of his limited knowledge....
