Gotta Love the 3135 Caliber

[Mr Daytona]

Only other watch people would appreciate this. I measured the timing of my brand new SD400 from August 12 to August 22 and it was only .30 seconds slow per day! I then wound up the watch, set it to time.gov and wore it. Measuring it again, I found that from August 22 to September 5 it was only .64seconds slow per day. That is some amazing accuracy for a mechanical watch!

Yep great movement & rock solid.

It's the only sense I have.......

Is that .64 seconds adding up every day, or each day, its only .64 seconds fast TOTAL? I have never understood this.

It's per day on average for my watch.

awesome, how did you time it? do you wear them? wind them after a certain number of days? thanks!

Set the time of your watch to a reliable source such as time.gov, wear it normally for a period of time then compare it again to the same time source. If you wore it for a week and it's 7 seconds slow then on average it's 1 second a day slow. Simple math problem.

Fantastic movement!

Thanks! I though you had a different method.

Yes my Cal 3135 has consistently run +0.7 sec/day since it was new and it is now 3 years old.

The Caliber 3135 is seeminly always on mostly every credible "Top 10 Watch Movements of All Time" list or such. And frequently in the top spot or at #2

Sorry to thread jack, but I set my 3135 movt this morning at 8:26:00 and checked it against time.gov it is ahead by 4secs now. As far as I know it was recently serviced before I got it. Any thoughts?

Your watch is a Rolex. The only reasonable conclusion: time.gov is 4 seconds slow.

Give it more time, say a week or so then compare. I wouldn't use just one day.

[pacific17]

Thanks Mr. D

[Daytona4130]

I'm a big fan

[jack81]

Nice. My ym minus 2 sec a day now. Still very happy with it.

[jimi]

That's great!
I'm sorry but I can't give you a figure on my 12 days old DSSD. It's been Zero since I received it and it's worn 24/7. I'm not surprised with this as my 16013 is also doing the same. :)

It's all in the regulation. The ancient 1575 movement in my GMT 1675 will stay within a few seconds of perfect for months on end with basic regulation close and doing some overnight self-regulation. Between watch rotations, July 1st to Aug. 31st, the GMT had gained 3 sec., which calculates at <.05 sec./day.

Newer movements don't self-regulate as easily since they are generally more consistent between resting positions, so it may be harder to keep these watches spot-on for the long run unless basic regulation is near perfect. For example my modern cal. 4130 Daytona runs 5 sec./day fast on my wrist and fast in all positions, so self-regulation isn't possible without getting basic regulation closer. I only wear the watch for a day or two on special occasions, so I don't fret over it.

I've even gotten my Tudor Big Block chrono with Valjoux 7750 movement to stay within a few seconds of perfect for weeks on end by following the procedure I use with the GMT. Like the GMT it runs fast with dial up, slow with crown down, and even slower with crown up--just as Rolex describes for older movements. It runs a few sec./day fast on my wrist and simply positioning it crown up overnight keeps it very close.

My SD4000 has the best movement of all of my watches, very smooth winding.

My Montblanc uses the highest grade Valjoux 7750 day+date and it is incredibly close to perfect over a week maybe +3 to +6 seconds. I don't do any sort of positional regualation and wear it and most days I use the chrono to time something inane just because I can...

You guys confuse the crap out of me. I don't have a clue how to test if my watch is fast, slow, or fast-slow or what. I put my watch down for the night, sometimes on its side, sometimes on its back. The next day I put it on. Check my iPhone for the time, look at my watch, smile....then clasp the bracelet down. Done. Out the door. I haven't ever tested either of my watches. Nor have I had need for concern either.

Edited to add...I am seriously too goofy to answer posts tonight & I shouldn't be. Sometimes the seriousness of all this watch stuff just cracks me up.

Enjoy your watches. :-D

The Valjoux 7750 is a chronometer-grade movement that very easy to regulate internally, unlike the Rolexes with the Microstella screws. I could get the Tudor closer, probably to a second or two per day variance without positional regulation, but laying it down with crown up overnight in its current configuration is easy enough. It tends to run a bit fast on my wrist and crown up slows it down about 4-5 sec. overnight. I don't mess with the Rolexes myself, though, as stopping the balance wheel with tweezers while screwing in or out two microscopic screws makes me nervous. I'll leave that to the watchmakers. Regulating to +2 sec. with dial up usually gets them very close.

I like your idea of using the chrono on a daily basis and might start doing that myself for kicks. The problem with the Tudor is that its sub-dials are hard to read with its polished SS hands against a black background, and the Daytona is no better with its white background. The Montblanc chronos I've seen suggest that more attention is paid to readability in those models.

GMT Time. Adjust for your time zone, but the only important part is minutes and seconds. Refresh often, as it can easily get out of sync.

Maybe you're not the goofy one. You're not the one fretting over a few seconds on an expensive mechanical watch when near-perfect time could be achieved with a cheap digital. There's something weird about all of this but I like it.
