I recall you bought your watch new in LV in the beginning of the year? Depending on how long it might have been at the AD, chances are that your watch has "settled" in over the past few months.
My experience has been that a watch that has been properly regulated right after a full restoration will run a little bit faster (say 3-8 seconds/day) after a few months - as the oils have become better distributed and any "wear in" has taken place. If I think it runs too fast, I take it in for analysis and if it is running consistently, have it re-regulated to slow it down a little bit. Usually the accuracy/precision will last for years and when it finally gets to a point when it runs too slowly, I know its about time for another service.
Your watch will also be affected by your lifestyle. A watch that indicates very well on a timing machine will often run differently when on your wrist.
The position you lay your watch at night will also affect the overall rate over a 24 hour period (for example, if it runs fast on your wrist, you may find that there is a position that will run a little slowly when you're not wearing it, therby "balancing" things out over a full 24 hour period).
Without a timing machine, you will need to be patient and time the watch the old fashioned way: wind it up and let it sit in each of the 6 positions for 24 hours to measure how fast/slow it might be (you can try to shorten the time up by timing for 12 hours, but 24 hours is preferred). Besides these positions, also time the watch when it is on your wrist (which might be 8-12 hours?). With this information, you will have a better understanding of your watch's current performance.
As MKVC said, 13 seconds over 29 hours sounds a bit too fast for me for a quality VC
. If you don't want to take a week to test Vachy, then see if you can take it to a VC AD or watchmaker that you trust to analyze it on a watch timer. (My wife bought me one for Christmas last year, she had no idea how much fun I would have with it - so she is very happy that I enjoy using it so much!).
I would say that the most important thing to look for is that Vachy is running well and consistently in each position, ideally with little variation between the positions. If it is running this way, its a minor thing for VC to regulate the watch for you. If it is running oddly, Vachy is still under warranty and VC will take care of anything that needs to be done.
For a couple of personal examples:
- My oldest VC is a 1908 Chronometre Royal pocket watch that has been fully restored by VC. It runs within a range of +3/+7 on a timing machine when put in all 6 positions. It runs at +3/+4 s/d when in actual use (in my pocket during the day and resting at night)
- My newest VC is a 31-Day retrograde bought in 2006. It runs within a range of -3/+1 on a timing machine when put in all 6 positions. I can't tell what it runs at when I'm wearing it because it doesn't have a seconds hand
Expect the best from VC, I most certainly do. I hope this info is helpful.
