The Explorer 36mm: How can it be so accurate???

[simonthepilot]

I've had it on everyday since wednesday and it's only deviated -1 sec. during all these days. And since friday it's dead on -1 sec, basicly exactly as the atomic watch I keep comparing it too.

How can a mechanical watch be so accurate? My GMTIIc (sold) which had parachrome showed a daily deviation of aprrox -2,5 sec/day.

Is a possibilty that less complications => more accurate?

Another possiblity I am thinking about is wether Rolex has fitted the calb. 3130 with parachrome (the e-broschure on rolex.com do not discriminate on wether only the Explorer II have it, so maybe there is a slight chance?)

How accurate is your rolex?

Well I can't speak authoritatively as to why it is so accurate, but maybe it's because it is just such a darn nice looking watch!

Truen hooliganhooker, it really is a nice watch in the purest form.

My 16610LV is -1 sec between last monday and today (6 days). It's on my wrist night and day. I'm happy

I too have the Explorer, which I tested last week.

Over the first 2 days it gained 2 seconds a day; then for the next 2 days it was dead accurate and stayed at +4 from the first day I started timing. So I guess it averaged +1 a day...

Yes, one of my favorites >>> very pure, very minimalistic ,,, and very accurate.

Simon,

Where's your wrist shot?

At first I thought the Parachrom hairspring had something to do with it, but my SD also does what several Rolexes have done; run without gaining or losing for weeks, even months. My white-dialed Daytona didn't gain or lose a second for a year. My Milgauss has stayed dead-on for months. They both came from the factory that way. I recently got a BNIB SD which was running a few seconds slow a day, so I took it to the RSC in Toronto and they regulated it. Now it loses about 1/2 second a day if I leave it dial up at night, and it gains about 1/2 second a day if I leave it dial down.

These movements are so consistent they can be regulated to be as accurate as a quartz without difficulty.

The Explorer I is magical.

Purchased one brand new almost a year ago - has been almost quartzlike in accuracy - really impressed!

My Explorer 1 is also my most accurate Rolex ! I don't know why, but I just love it !

Lets get things straight the Parachrom hairspring is no miracle worker for accuracy.Its a just hairspring very much like the Nivarox one in your watch.Many on forum have vintage watch 30- 40 years old show remarkable accuracy.Now the cal 3130 is now basically the cal 3135 but without the date complication.Accuracy comes mainly how a watch is regulated and how it perfoms on wrist.With some watches its possible to self regulate while perhaps on wrist it might gain 1 or 2 seconds.But while resting at night in certain position could loose those couple of seconds overnight.

It climbed Everest w/ Sir Ed....of course it's precise!
I just climbed three flights of stairs, mine is still running and very precise at this altitude.

My Explorer is gaining about 1-2seconds a day, which I'm completely happy with. However, if I wanted it to lose a second or two over night, what position should I leave it in?

Thanks

I read an article which said the people at C.O.S.C. stated taking into consideration the smaller movement, the Ladies Datejust are the most accurate of the Rolex watches.

You could try watch vertical crown up first or vertical crown down

Quite true in proportion to movements sent for testing,now Rolex sends the most bare uncased movements for testing at COSC.But in proportion to movements tested the ETA 2824-2T and the ETA Valjoux 7750/1 has one of the highest first time pass rates.

When people start claiming their automatic mechanical movement watches are keeping time constant with an atomic clock.,,I begin to call B.S !

Well all I can say your Daytona must be one in ten million,not to loose or gain even a second in 12 months.Even the finest Japanese quartz are only accurate too a few seconds a year.I know Rolex movements are good but not that good. IMHO it would be impossible for any mechanical watch to run for 12 months without any deviation whatsoever, unless it was running on fantasy island.

Lovely little piece...
