5146 Partial Hack
Jul 12 2008,21:35 PM

Wondering if this behavior is normal...?
My 5146 runs approx. 10 seconds fast per day. As a consequence I reset time back by 1 minute every 6 days. When I do so, the action of setting time back stops the second hand from moving forward and appears to stop the movement as well. I know there is no hack function, though this seems almost like a partial hack. It's somewhat disconcerting to see time "stand still" as I move the hands backwards.
Any thoughts?

10 secs a day???

Please do not adjust the watch backwards coz you'll only end up with a damaged caliber, your watch requires some serious rate adjustment from a qualified technician coz 10 secs a day is a hell lot to tolerate for a Patek Philippe.

my pp5146 accelerates approx i second every 15 to 20 days when checking with the us time in colorado. last year i was ap patex in new york city and they checked my 5146 and they said that was ok. i try not to go back as much as poisible because i am woried to desynchronize any of the functions. iwould have it checked by your AD.

One second is quite normal. . . i dont think you should worry about that buddy! [nt]

Setting time backwards...
Jul 13 2008,19:46 PM

I've done some research on the matter of setting the time by moving the hands backwards - I am more confused than before. Multiple people suggest there is no risk to moving the hands backwards while others strongly assert (as you do) that it may damage the watch. If you can't move the hands backwards, what do you do if your watch is fast - say by 3 seconds a day and want to set it accurately after a period of time? That is, over the course of 20 days your watch will be one minute too fast. Should you move the watch forward to set it accurately? If you do, won't it also advance all of the other settings - moon phase, date, etc...? This doesn't make sense to me.....I'm perplexed....

The best solution that i would propose is not to wind your watch and leave it alone a day prior to the adjustment interval. Let the balance wheel stop oscillating, wait for a couple of minutes, and then adjust time forward according to your wish, wind your watch and enjoy the good life.

Same thing

I'm experiencing the same thing. I bought my 5146P in Jan 2008 and it was losing 12 sec/day.

I brought it to Patek in NYC and the service was great, however, the technician screwed up when he resealed my watch. The gold part in the back that rotates to wind up the watch was jammed. I didn't notice this until days later, b/c the watch wasn't winding in my winder.

I brought it back a second time and the manager was very accommodating and I even got a gift. After this repair, the watch was still losing about 2-3 sec/day but I felt it was acceptable. About 1 month later, it started losing 5-6 sec/day. I got some advice in this forum about letting the new watch break in. Right now my watch loses about 7 sec/day and I'm thinking about bringing it in.

I also have a 5396 and it loses less than 1 sec/day.

No harm from partial hacking

Both my Breguet Marine Big Date and Patek 5146 stop the seconds hand when setting the time anti-clockwise. I have stopped the seconds hand briefly in order to set the time accurately in both watches and no harm appears to have come to them.

Regarding accuracy, I would be interested to know whether your 5146 comes with a 315 (21.600 VPS - 3Hz) or a 324 movement (28.800 VPS - 4Hz). Mine comes with a 324 calibre (the calibre mounted on 5396) and it has run very consistently at +/- 1 sec. per day for the two months or so I have had it. I do not see why a 4 Hz calibre needs to be more precise than a 3 Hz calibre, provided they are regulated properly, but there are indications that Patek is gradually replacing the 315 with the 324 calibre in 5146.

Quite valuable piece of info. . . . . Thanxx! [nt]

Good Solution
Jul 14 2008,13:11 PM

Good solution... have the watch stop and move it forward to reset it. Though it still doesn't answer the question regarding setting backwards and potential harm to the movement. FYI... I have the 315 movement.

"...move hands in either direction..."
Jul 14 2008,14:01 PM

With the risk of of offering too much information...
I just read the Instructions that came with the 5146 - something I should have done before I ever posted, of course. It reads: "SETTING THE TIME Pull the crown out and move the hands in either direction to the correct time. If you move the hands beyond midnight, all Annual Calendar displays will be advanced as well. It is not recommended to move the hands backwards beyond midnight, as this would also affect the calendar displays. However, it would not harm the movement."
