New question;

I'm 5s fast per day. You could set your watch to it. I've been hacking it each morning.

Is there a specific position I could lay it in at night that is likely to eat up those 5 seconds?

I know this is trivial and pedantic but if I'm gonna own the thing for the next 40> years a small change of habit is worth it.

I do a lot of IT stuff where having the EXACT time is actually really useful.

A few, well quite a few decades ago I was taught to keep my daily wearer face up on a flat surface away
from Radios and TVs with speakers or anything with magnets.
I've owned my 3861 Speedy for more than a month now, worn it everyday and so far it's running spot on.

5 seconds is an awful lot play with and outside of the positional variances we normally expect for watches these days.
2 or three seconds maybe but 5 is a bit of a stretch.

Simply try resting crown up or down yourself and see what you get out of it.
Generally speaking, dial up or down where the balance is in the horizontal plane will yield faster timekeeping whilst the other positions usually slow the watch up a bit👍
You're doing well with a solid +5 in terms of precision.

If you're regularly getting a very consistent +5 despite positional variance, you could have the watch regulated to ~+1/+2.

It's been between +3 and +5 since I got it. I'll try keeping it on its side overnight and see what that does. Definitely seems like it gains the most time when it's sitting on my nightstand.

Interesting - is this just based on personal experience?

Like I said in the first sentence with the first word "Generally".

Yes, it has generally been my personal experience and my understanding is it's a relatively accepted norm by others even if it may be a myth.

I'm confident you are in a position to bring clarity👍

OP will just have to play around with different positions at night and see if one produces better results, there are no rules in which one position will make it run slower or faster.

If your IT job requires really accurate timing for some of your activities a mechanical watch is NOT the best option..

When you tell him his best option for work is a quartz watch, then what?

The reason I asked is I wondered if you had some specific theory why this would be so, or if it was just anecdotal.

There’s no technical reason why what you have described would be typical. In fact since amplitude is higher in horizontal positions, the opposite would be more likely (depending on the level of isochronism). There’s no direction I’ve ever seen from watch companies, or given to watchmakers in school or anywhere else, to intentionally adjust a watch in this manner. What positions run fastest or slowest is actually pretty random.

Cheers, Al

I’ve noticed an odd behaviour with my new 3861 Speedy’s chrono function… the sweep hand will sometimes instantly skip forward upon engagement… the amount it skips forward seems to randomly vary… sometimes it doesn’t skip at all.

@Archer have you heard anything about this being an issue? A local friend who owns the new Speedy checked his when I mentioned it to him and it performs the same.

Here is a link to a video of what I am seeing:

That's probably the best advice.

I have a simple Weishi no3000 tester that I used to measure 3 of my Speedies on. I saw a bit of a pattern so I repeated for each, with the similar pattern holding true. For my 3 Cal 1861's, they were fastest with the crown to the right or up. By no means are my results reliable (cheap tester) but they gave me some interesting data points.

Many thanks Al👍

I always wondered about it all as I get the concepts around amplitude as you have outlined and how they should theoretically slow down when amplitude increases. Especially when the balance is in the horizontal position.
Perhaps my watches are predominately outliers somehow. Actually, just recently I have been playing with them and I'm typically trying to slow most of them down just playing around with overnight positioning. No joy dial up or dial down, in fact the opposite.
Then there are two I have where I sometimes am trying to speed up, but I'm not getting much joy there either as they don't vary much over the different resting positions so I just accept that periodically I have to advance them a few minutes to compensate as required. It helps with my time management😉

Whilst waiting for your response.
I was contemplating if there may be an undesirable issue of some description, where it's revealed by the timekeeping speeding up in the dial up or down position👎
But seeing as you have said there's no rhym or reason to it, i suppose I can just simply chalk it up to life and how things work out😉

Thanks gostang9.

My 1861 is one of the watches I am experimenting with to slow down a bit as it runs between +3 and +6 on the wrist.
I shall redouble my efforts to see if I can slow it up some more by using the dial up or down position👍

This is an inherent possibility in any horizontally coupled chronograph. It happens because of the way the teeth engage between the chronograph wheel and the wheel on the coupling yoke. Nature of the design.

Thanks Al. So am I right to assume that all 3861’s likely behave this way?

It doesn’t bother me at all… I’d only be worried if it was a sign of something broken or functioning improperly. Cheers!

As I said, any horizontally coupled chronograph can do this...

Mine does this too and I don’t think it’s a problem. Partly because I timed it with a stop watch a few times and it seems accurate (more so than my human error of pressing buttons). Also I found that if I depress it quickly it’s not an issue at all. Try that and let us know what happens!

Similar. I tested over the past few days and got 64 hours without any Chrono use. I suspect if I had used the Chrono regularly (as I tend to do) during that time, my results would have been similar. Some details here: https://omegaforums.net/threads/3861-power-reserve.131459/#post-1783946

Replying to my old comment here. As a further data point. I recently had to replace my 3861 for a new one (details in separate thread), but re-ran this Power Reserve test again on this separate new model and got just over 63.5 hours of PR.
