Setting the time with Overseas Chrono

I recently purchased the OC and it's a great looking accurate timepiece. I have noticed that when setting the time with the crown pulled out to the last position the second hand on the 6:00 subdial continues to move, which makes setting the time precisely impossible. 

I contacted VC and they said it should stop but I called the boutique in NYC and the person told me it continues to move and the dealer I bought the watch from checked 3 different watches and none stopped. Does anyone have the answer?




OS Chrono is non-hacking

The cal. 1137 and the Piguet 1185 it is based on are non-hacking movements.

Here is the communique from VC


Thank you for the message.In regards to your inquiry, when setting the time on your Overseas Chronograph the hand on the seconds sub-dial should not keep moving.  Please see the attached document for the winding, setting and chronograph instructions for this timepiece.  If there is still an issue with the second hand sub-dial, then we will need to have a watchmaker examine the timepiece.  Further to your inquiry, the power reserve for an Overseas Chronograph is approximately 40 hours, but if the chronograph is activated the full power reserve will drop to 30 hours or less.If you still have an issue with the timepiece functioning properly, let me know where you are located and I will provide you with our nearest authorized locations that would be able to assist you with the timepiece.As always, I remain at your service. Best regards,Melanie Vacheron ConstantinNorth America Concierge Service

Tick-Talk and the Watchmaker at the NYC Boutique (Eduardo) are correct.

VC Cal 1137 does not have a stop-seconds / hacking seconds.

I know Melanie, but do not know where/how she received that information.

the back-hack
12/30/2015 - 19:37

there is a "back-hack" where one puts slight pressure backwards on the crown to essentially reverse the drive train and stop the seconds hand.  Some watchmakers claim this may damage the movement, while some manufacturers actually recommend the procedure for setting their watches.  I believe if the movement was designed to back-hack then all will be well.  Blancpain recommends back-hacking for certain time-only automatics in my multi-model owner's manual, but are silent with the 1185-based calibers.  I'm not sure what to infer from this indecision

Exactly what I do

Back-hacking doesn't cause any damage to this movement, to my experience.

As you guys have already pointed out, the reply from the person at VC is just wrong.  I own three watches (AP ROC, VCOC and BP Leman chrono) with the same F. Piguet 1185 movement and it is non-hacking.  I also have a Panerai 121 with an El Primero movement and it doesn't hack either.  It really used to bother me but doesn't anymore.  If you think about it, life doesn't really require that much precision.  If it did, we'd all have to wear atomic watches. Now I just take my watch off the winder and look at my atomic clock.  If needed, I'll adjust it to the nearest 1-2 minutes and go.  

Enjoy the Overseas Chrono!  To me it is one of the best and most under-rated sports chronographs out there.
