and, usually, JLC times them to be within 10 sec/day. Since 2003/4, all Reversos undergo the 1000 hours control test, which stipulates timekeeping accuracy within -1/+6 sec/day.

you should have no problems with the timekeeping of a Reverso...this is mine and I get about +2 seconds a day from her...

I must remember to get some more pics of her soon too as most of my pics are terrible..!!
Please share pics of yours when you get her,
Andy.
Hi Pavel,
Click here to link to a post I did on the performance of the Cal 875 Grand Date a while back . This particular Reverso performed very well as you can see.
My wife's Reverso Memory has been in continuous use for more than 5 years and is consistently within 5 seconds per day.
As they say about aged wines: "there are no great vintages, only great bottles", your experience with an individual watch may vary, but the general comments I hear about Reverso's are very reassuring.

Welcome Pavel!
I have some Reverso’s – never any problem with accuracy!

Hello Pavel:
At first, my reverso Grande date used to delay about 13 seconds per day. After six months I was able to know how the watch should sleep every nigaht in order to avoid it delayed.
I realized that when it sleeped with dial down, the watch worked +1 second/day. That was perfect.
The less important matter in a reverso is its accuracy.
Best Regards from the quite north of Spain:
