UB7 Posted October 1, 2007 Report Share Posted October 1, 2007 I was just wondering, because I know with gens this trick actually works, but does it hold true to our rolex reps? If your watch is running a little fast OR a little slow, Rolex suggests the following: When you take your watch off at night, lay it in a position that assists in adjusting the time without the help of a specialist. If your Rolex is a little slow during the day, lay it flat, with dial up as this position tends to gain a few seconds during the course of the night. If the watch is running a few seconds fast, lay it in a vertical position with the crown down as this position will tend to lose a few seconds per night. If your Rolex is running several seconds fast per day, lay it in a vertical position with the crown up. This position tends to lose a few more seconds per night that the previously suggested position. Quote Link to comment Share on other sites More sharing options...
rag9fx Posted October 1, 2007 Report Share Posted October 1, 2007 Do you mind if i ask where you got this excerpt from ? certainly didn't come with any new [gen] Rolex i have bought recently. Quote Link to comment Share on other sites More sharing options...

rag9fx Posted October 1, 2007 Report Share Posted October 1, 2007 I have to be honest with you UB7 of my many years of genuine rolex ownership i have never seen one of those cards/ papers... Has anyone else ? is this some sort of rare or vintage piece of rolex packaging ???? Quote Link to comment Share on other sites More sharing options...
freddy333 Posted October 1, 2007 Report Share Posted October 1, 2007 Yes and it works (and not just for Rolexes). Quote Link to comment Share on other sites More sharing options...

UB7 Posted October 1, 2007 Author Report Share Posted October 1, 2007 Interesting...So this applies to all automatic watches? I wonder why this is... Quote Link to comment Share on other sites More sharing options...
thewightstuff Posted October 1, 2007 Report Share Posted October 1, 2007 as far as i know its to do with friction. dial up places everything centred in its respective holes and allows smoothest running with least friction. sideways position increases this causing slight drag though my crown up and crown down would make a difference to this is unclear to me. i sit my 5512 crown up at night when wearing it during the day and it keeps almost bang on.

tourbillon Posted October 2, 2007 Report Share Posted October 2, 2007 Absolutely dead on with the above replies. It has to do with the number of points of friction. Generally speaking, a movement with the dial up will have "half" of its pivot points resting their weight in their respective jewels and therefore, less friction. A watch held crown up or crown down will have all of the gears' weight/friction on both its top and bottom pivot points, and therefore will run a little more slowly.

UB7 Posted October 2, 2007 Author Report Share Posted October 2, 2007 (edited) Awesome...thanks for the replies guys, interesting so this does indeed apply to all auto's.. - my daytona has been running around 4 seconds fast a day, gonna give this a try and see how it works because i dont want to open the caseback as it has been enduring my daily showers/handwashing with ease, dont want to ruin this because i know once i pop the back it will not keep the water out as good...

Dizzy Posted October 2, 2007 Report Share Posted October 2, 2007 I dont take my watch off at night this is an old trick my watchmaker told me many years ago and it does work but we're onlly talking a few seconds either way. Im not that concerned with accuracy. As long as i can go a couple weeks without having to reset the time, then im happy. Good tip though UB7 and good answer Nanuq. I always figured it was just the weight of the second and minute hand and the gravitational forces acting upon them, but i guess theres more to it than that Lonnie Quote Link to comment Share on other sites More sharing options...
UB7 Posted October 2, 2007 Author Report Share Posted October 2, 2007 (edited) Thanks guys!! Heres another interesting diagram I found in regards to regulating time, although its a little confusing: Im not that concerned either but my daytona running 4 secs a day fast is just enough to annoy me...i want it to be +/- 1sec is which is within COSC specs...Also, does anyone actually wash there watch with warm water and soap?? I would think soap would be harsh on the SS... Since this is applicable to all auto's perhaps a moderator can move this to the general discussion section Edited October 2, 2007 by UB7 Quote Link to comment Share on other sites More sharing options...
jfreeman420 Posted October 2, 2007 Report Share Posted October 2, 2007 Everyone knows you are supposed to have so many watches that you don't have enough space on the winder and you wear a different one every day so you will be setting the time regularly on most of your watches. Now you don't care which one loses or gains because you will never know.......... Amateurs........... Quote Link to comment Share on other sites More sharing options...

I would think soap would be harsh on the SS... Cosc is -4/+6, so if your Daytona is only gaining 4 seconds a day, it's keeping time as well as a genuine Rolex would. If you want +/- 1 second, go to Wal-Mart and get a Timex, otherwise, congratulations - seems like you got a good one. Quote Link to comment Share on other sites More sharing options...
mag1119 Posted October 2, 2007 Report Share Posted October 2, 2007 Thanks for the great advice. Before, as I was inadvertently leaving my watches in any of these positions, I wasn't really sure why it was gaining or losing or how to correct it. Now I do.

NRG Posted October 2, 2007 Report Share Posted October 2, 2007 (edited) The positional errors noted above are to do with the point of attachment of the balance spring and the horizontal centering of the balance spring. Jules Grossman discovered in the 19th century the most critical adjustment is the point of attachment of the balance spring to the centre collet of the balance wheel. As mentioned earlier in the vertical position the balance pivots have more friction thus reducing balance wheel amplitude which increase the rate of the watch. The attachment point can be adjusted to minimise but not eliminate the error introduced by the vertical position. Some manufacturers choose the point of attachment to lower the rate in the most common vertical position IE:Crown Down with low error in the Crown left position and a relatively faster rate in the Crown Up position but other manufactures choose different attachment points with different results. So what works for one watch *may not* work for another from a different manufacturer. Hope that helps...
