Accuracy varies between a few seconds loss and up to over 9 hours loss over a 24 hour period, when worn and kept fully wound. The fault is intermittent and has has occurred upm to three times in one week, but the watch has once remained accurate to within a few seconds per day for as long as 11 days. It has been back to the manufacturer twice and they have tested it for a day or so and they cannot find a fault. It has been back to the retailer three times and on the last occasion they claim that one of the staff wore it for a week or so and it only lost one minute. I have a record of all dates and time losses over 24 hour periods. Can you offer any help? It is a brand new Raymond Weil Parsifal Reserve de Marche 42H. Many thanks, Tony Butler.

Hello Mr. Tony.
Have you try to change the battery and put in a new battery to check if the accuracy still varies?
Put in a fresh new battery in to check if the problem continue.
Toggle the button to change the hours, minutes or just move the button and then set it to the correct timing.
Check if that gives any difference.
If it still does, you have to dismantle the watch, make sure the hour arm/needle, minute arm/needle and second arm/needle are fixed properly together as it may be the cause of inaccuracy.
You can get that done at the retailer if you're afraid to dismantle it yourself(it's fragile) or as soon as you spot problem with it, take it down to the retailer.

Hope it helps and sorry if it doesn't.

My friend, I have some help for you, but it is not what you think. Every mechanical watch I have ever worn, and I'm talking about dozens of watches, has acted odd in this respect. No matter what, my watches have run 5 minutes slow. I would set it in the morning, and by supper time it was 5 minutes slow. A month from that time, it would be five minutes slow. If I set it again, within 8 to 10 hours, it would be five minutes slow. If I set it 5 minutes ahead, within 24 hours, it would be 5 minutes slow. This for manual wound watches as well as auto wind models.

But ... when I changed the metal expansion bracelet for a leather strap, it remained accurate with in seconds.

There is no rational explication for this ... but tell you it was so.

This is how I solved my trouble ... and it will not necessarily work in your case - yours is TOO erratic.

(1) I just accepted that my watch was 5 minutes behind,
(2) I wore a very inconvenient (and not cool) leather strap that needed frequent replacement,
(3) I moved to electric watches,
(4) I stopped wearing a watch when I retired,
(5) When I entered the work force again, I discovered my cell phone worked great at being a watch.

Since your watch has been in the repair shop many times, and they report that your watch works normally for them, it would be nearly impossible for them to regulate it - they cannot reproduce the symptoms. Try this, put some insulating material between you and your watch, a wrap of paper or a joggers 'sweat band' or some other way to isolate you from your watch and see what happens. I had a friend that said he painted clear fingernail polish on the inside of his watch with metal bracelet and that helped in his similar situation.

What happens if you let it set on the table? Does it lose of gain? Do you live near high tension power lines?

What ever --- I hope you get to a work around of some kind. I doubt you will 'solve' this trouble unless you go see the witch doctor. Good luck and thanks for using FixYa.com

Hi if its new then send it back as their clearly is a fault with this watch its clear that a part in the watch is sticking causing the time loss ie the second hand would stop going round then would free itself if this is the case then the watch would need stripping and rebuilding and this is beyond anything a novice could do to put right,

now the other problem you could have is that the hour or minute hand may not be fitted correctly causing it to slip if the watch was shocked or knocked at any point this could cause one of the hands to jump round a bit causing it to display the wrong time but to put this right it would mean stripping the watch down and this is just something you would not be able to do yourself.

what you could try is not wareing the watch for a couple of days leave it somewhere where it cant get knocked then see if it loses any time if it does then its clear that their is a sticking part inside the watch with may just need greasing but could need parts replacing, how ever if it dont lose time when its not been worn then this would point towards the hands been loose causing them to jump making the time alter.
either way this should not be happening to a new watch i would take the watch back to where you brought it from and get it exchanged this isnt something you can repair yourself as you would need specialist tools and it would be to difficult to do.
even if you took it to a watch shop they would send it back to the makers as its the only way you can get this repaired.

Check your warranty and take it back and get an exchange if this is possible.

Let me know how you get on or if you need further assistance ok
