Tudor Accuracy Shock

[Robbie68]

I bought a Black Bay Bronze just over two years ago, as I always do I set it using the Emerald time app. I monitored accuracy loosely for the first couple of weeks of wear and it appeared to be +/- 0 so I was happy there were no issues and didn’t check again. Anyhoo long story short the watch has been worn 20% of the time and the rest spent on a Wolf winder, I wore it this morning for the first time in a while and about 2.2 years from being set (didn’t bother wearing when it needed adjusting for daylight saving). So… after 2.2 years it has lost 5 seconds!! I’ve owned many, many watches and have had nothing that comes even close. Well done Tudor!

Wow

That’s surprisingly accurate I would have expected it to be a little further out than that. Good on Tudor

[PandaLover]

Wow Very nice

[stevestil]

Another point for Tudor!

Are you sure it's not 12h 0m 5s off?

[hartsy]

Dang so this watch was on the winder for 2+ years and constantly running?

That is an incredible accuracy rate, wow!

[MRBolton]

None of the Rolexes I've had would keep that good of time!

That what I was thinking.

Over 69M seconds over that time period. To be off that little is luck. For it not to change much over the 2.2 years due to component wear, break in is something.

Tudor makes a nice movement. When I put my BB58 on the Timegrapher, it just spits out 0’s. I, for one, am not surprised.

Well I wore it on and off over the two years and it was always at the correct time, I think at some point during a twelve hour loss I would have noticed.

Not surprised. Tudor BBB is the most accurate watch in my collection. I have the original brown dial one. The only problem are the straps: they don't last although I rarely wear the watch. The leather one is especially short lived, at least from my experience.

[Robbie68]

Try Gunny straps, I’ve had some for ten years and worn them a lot, they seem to last forever and you can have them tailor made.

[msum]

That’s phenomenal.

I’d be scared to ever get it serviced. I kid, I kid.

[WatchGuy1966]

Never changed for daylight savings time over the years?

[Robbie68]

No, I did mention that. I have many watches so on the odd occasion I went to wear the Tudor if it was an hour out I’d pick something else.

[Harry-57]

My BB Heritage keeps perfect time. It's uncanny.

The Tudor Black Bay Bronze runs with a self-winding mechanical movement, MT5601, which is COSC certified (-4/+6 s/d).

Over a period of 2.2 years (26.4 months) the watch was worn 20% of the time and remained for 80% (21.1 months) unworn on a watch winder. It is understandable that the caliber did not stop running.

But, imho, it is very unlikely that a mechanical caliber, here the MY5601, only loses 5 seconds in 21.1 months while remaining on a watch winder. OP does not provide any type of measurement over the 2.2 years period, which supports my doubts about the result.

Very nice.

[Robf52]

Very impressive.

[SudiYunus]

Never checked accuracy on all of my watches :)

[RRGHOST1]

My daughter bought me the new Opaline Tudor GMT about 8 months ago. its running 3 secs fast in 48 hours. None of my Rolex were that good. Well done Tudor.

[Scottyboy]

Wow, impressive for sure.

My BB54 is wonderfly accurate, far more so than my Submariner.

I've owned 3 Omegas, and they are consistently more accurate than anything I've bought from Rolex, Tudor or GP.

So I’m lying because I have nothing better to do? The watch was set accurately +/-.5 second 2.2 years ago, it’s run constantly since then, it was checked against the same app used to set it originally and it was 5 seconds slow.

That's surprisingly accurate; Credit to Tudor

I’d be wondering if I was sold a fake quartz one!

I have one watch that is phenomenally accurate but it is very slightly fast or slow depending on how I wear it in any given month. It would definitely drift one direction or the other on a winder.

Yes it's actually pathetic how bad they are. The leather one from my dads silver BB needed to be changed after a couple of months.

I never check the accuracy of my watches actually
