When your position just doesn't get it done...

[WatchinMD]

So my new BLNR was about 2 seconds slow in the last 2 days in spite of wrist time and resting face up at night. I hypothesized that it was the axial rotation of wearing movement that would tend to make the movement gain time. To test this I suspended the watch head down but level, holding the open clasp segment between 2 fingers. Then I applied short rotational oscillatory movements for a few seconds. Voila! the watch had gained 2-3 seconds and is now about +1 second.

I searched the forum and found a ton of accuracy threads but did not see this mentioned.

I assume this is not detrimental to the movement. If not, it seems this is a much more convenient technique foe dealing with a slow watch than hacking it, setting it a minute ahead and letting time catch up.

You mean that you got the watch to gain 2-3 seconds in about as many seconds?

[WatchinMD]

Yes that is precisely what happens. I duplicated the effect again today. I hacked my watch to make it about 2 seconds slow as demonstrated in the first picture. I then applied the rapid oscillation axially for about 5 seconds in the position demonstrated in the second photo and the result of the increment is demonstrated in the third.

Mine gains 2 seconds per day... Any quick voodoo besides hacking to make it lose a couple?

just so you know, I think the links are suppose to be somewhat even on both sides so the watch can sit centered on your wrist..

You either are incorrect about the timing, there is something wrong with your watch, or you're doing something horrible and bizarre to your watch imho.

Hmm...I know that you can speed up the timing somewhat based on physical activity...but it seems for that much of a gain the movement would have to be pretty intense. Can you post a video to show what you are doing? Thanks,

I didn't realize the timing could be affected that easily.

2 links from 1 side looks asymmetric with the clasp open. Sits fine on my wrist.

That's actually not true usually less links on radial side of wrist makes watch centered correctly

Mine has four at six o'clock and six at twelve o'clock

Perhaps if you remove the stickers that will fix your problem

This, something seems off.

The effect on the timing is unequivocal and reproducible.

The watch is about -2 seconds for a week; it seems to be working fine.

It is commonly observed that watches may run slightly faster when worn. There has to be a physical explanation for this. True that timing may be affected by position but while one is wearing it during the day, position changes constantly so I would expect that effect to be minimized. That leaves transnational or rotational movement as the possible mechanisms. Of the 2, rotational seemed more likely to affect a rotating balance wheel mechanism. This was an experiment to test that hypothesis.

I would certainly welcome input from the technically knowledgeable members as to whether this could have an adverse effect on the movement.

HAHAHA. My wife says the same thing. In due time.

[The Joker]

This thread is a joke, right?

I'm confused, I've just woken up from a nap.

I think the 12 o'clock position should always have more. I just got my SubC and thought the links should be even. But after help from TRF member IMCBAJ and doing some research it became clear that they should be uneven. When the clasp is closed the 12 o'clock postion evens out with the 6 o'clock one.

For example on my watch the 12 postion has 6 or 7 links and the other side only has 4 links. When the clasp is closed it sits even in the middle of my wrist.

Nope. You'd think someone with a 116610 would recognize that for the clasp to be centred you need more links on the 12:00 side.

I did try this out of curiosity and can confirm that it works. I will not be doing it again though as I think this might be putting too much strain on the hairspring. This type of shock might happen naturally when you wear your watch every now and then, and I am sure the movement is designed to be able to handle it. But doing it repeatedly and on a regular basis to adjust the time could degrade the hairspring and/or other components far ahead of their time.
