Tudor more accurate than Rolex

[Rori]

Hi guys,
Saw a post here on this forum about an app called toolwatch, I guess many here know about it but it was new to me not me. I gave it a try with my two watches, the one year old Tudor GMT and newly purchased Rolex SD43.
Now I don’t know how accurate this app is or if the test has to be repeated but first results are surprising to say the least.

Not surprised. Most of these watches run within cosc spec. After that it’s just noise.

Both are excellent results and one would see more variation than the difference between the two depending on who wears them. Nothing to worry about. Try letting your SD43 sleep on its side at night, crown up, and you'll be very close to zero in a 24 hr period.

SS SkyD blue is +7 sec a month. It comes down to good regulation on these modern pieces.

Assuming both have been manufactured or serviced recently, one is regulated better, that's all.

My 1980s GMT loses 1 second per week if I don't wear it every day, otherwise gain/loss is zero. It's all in the regulation.

This.

Just luck. Crown up, crown down. Too hot. Too cold. Give each a week in the wrist and take
Off same time each day and then see. Some weeks they run faster than others. Just noise as said earlier. Run for a week or two and then see.

Thanks for the feedback guys. No, I’m not worried at all but thought Tudor was less accurate than Rolex. Also wanted to know if this app is reliable. That’s all.

Both are new watches. Bought new from boutique so none had been regulated.

Out of the dozens of watches I’ve owned the most accurate by far was my blue Tudor Pelagos. It took 2 weeks to gain 1 second. Remarkable. Unfortunately it was uncomfortable to wear so I sold it.

I think that you are confusing "accurate", as if it is an attribute that can be seen on your app.

An "accurate" watch will hold that same +3.1 sec day-in and day-out for a long period of time. This means that you can regulate it more precisely and be comfortable over-time that it is "accurate".

I'm not saying that one is more accurate than the other, only that they have not been regulated to the same spec on your app.

Is this app just a stopwatch calculator that compares your local watch time drift to the atomic clock? That's how watchtracker works. Accuracy is as perfect as physics can make it but precision is based on your ability to click when the time displayed is shown on your watch. The longer you let it go between measurements the more precision you get. 1 second reaction time error per day (extreme example) vs 1 second reaction time error every two days. The latter has 2x the precision.

Human reaction time is 215 milliseconds on average or 0.2 seconds. So if you make a measurement on there once a day and you're an average person your error would be about that. The microsecond of atomic clock error would be 5 decimal places to the right and negligible by comparison.

I have a $45 Seiko that keeps better time than my GMT Master. I think we should definitely assume that a Seiko 5 is more accurate than a Rolex.

(I mean, obviously I'm being facetious about the conclusion, but I do love that my most accurate watch is also my cheapest. With this many tiny moving parts, luck is a meaningful part of accuracy.)

I agree. Every watch will chart its own pattern of accuracy depending on wear, climate, positioning and activity.

[Jostack]

Accuracy is a function of regulation. I assume manufacturers don’t regulate watches to their highest accuracy potential, but get it ‘in the ballpark’, and most of the time it holds to the published specification due to the precision adjustment and quality of the movement.

In my experience with personal recent purchases, the Tudors seem to be dialed in a bit better. Small sample group of 3 Rolex and 2 Tudor over the last year and half.

Their prices seem to be more accurate

Here are some 1960s Seikos regulated to similar or better daily rates than the above: https://www.rolexforums.com/showthread.php?t=694443

Every day I learn something new about watches thanks to you dear RF community.
