Tudor Ranger Power Reserve

[Old Expat Beast]

I finally got round to testing my Ranger's power reserve this week. Tudor claims "approximately 38 hours", but I got 43 hours 52 minutes. That's pretty much Rolex territory, right there

43 hours PR is very good, thanks for sharing, Adam.

[Matt748]

Excellent, Good to Know.
Thanks

[Rogdogg]

That's great. Cheers Adam.

I'm happy to hear, thank you for the info Adam.

With most all modern day movement today they all average around the 39-48 hours on a full wind. Even the Chinese Seagull ST19 manual wind power reserve is well over 40 hours.Now way back in the late 1920s a British guy called John Harwood from the Isle of Man UK,now he in took out a UK/World patent in 1923 for the first truly automatic winding wrist watch.

And he went on with backing to produce many thousands of these watches,but mainly owing to the very hard industrial depression in the mid 1920s to 1930s in the UK he went broke and out of business .Now old Hans Wilsdorf of Rolex being a very clever but very shrewd man bought and took up this auto-winding patent for the Rolex Watch Company,and in the very early 1930s incorporated it into the oyster design case. And with the newly acquired waterproof screw down crown patent that he got from Perregaux and George Peret now they first took out a Swiss patent in 1925 for the twin lock crown system .And with the Oyster type case,screw down twinlock crown and the acquired patent auto wind mechanism the first Rolex Oyster was born. But in those very early oyster days it only wound around 300 degrees now Rolex did improved the design by the help of Hans brother in-law,who made it more efficient by winding a full 360 degrees,and a power reserve then of around 36 hours.

Interesting nugget of history. Thanks Padi.

Rolex had to print a public apology to Harwood at some point for claiming to have invented the self-winding movement in their advertising, as I recall. Since then they have always specified "rotor-driven" or similar.

That is quite true but got to take my hat off to Hans Wilsdorf he wanted the best product for the RWC and he made sure he got them. Now when he had that great product he was at the forefront of marketing that product.He took every opportunity to market that product with things like the channel swim, WW2,Mount Everest etc.Without doubt he was a marketing genius, this is for me the greatest thing about Rolex the history of the brand.

Definitely a marketing genius, and quite a knack for recognising useful new patents filed in Geneva, then buying the rights to them, from what I have read.

Thanks Peter & Adam. That's fascinating.

I think in the golden age of wrist watch/automatic winding development the patent battles were pretty intense. So much happened so fast, compared with earlier timepieces. It's also interesting that the business has been around long enough that some patents, trademarks, etc. have expired (like the cyclops, I believe) and the climate has has changed a lot. I think much of watch history is as interesting as the watches themselves.

Thank you for testing the power reserve Adam. And with one quick search I was able to find this thread. Just what I wanted to know.

Hi Adam- I'm sniffing around the idea of a Ranger. I'm getting the impression you're quite impressed by them? Any views greatly appreciated...
Best wishes

[Chewbacca]

Hi Paul,
Your impression is spot on. I'm very impressed by the Ranger. Beats the Explorer 39 hands-down for looks and ruggedness, IMO. There seem to be a lot of these incoming recently, too. I guess you've seen the owners thread already, but in case not: http://www.rolexforums.com/showthread.php?t=396350

Hi Adam- thanks- have had a good drool over the other thread!
Can I ask what your view is of the ranger vs an explorer? I much prefer the font of the ranger for the Arabic numerals but prefer the Mercedes hand and the bracelet/case interface in the explorer....and then there a cost evaluation as well... Fully aware that this is s personal preference dirt if thing, but have you had explorers as well and can you give a balanced view between the two? No pressure! ��

I have an Explorer 114270 but at 36mm I would not compare it to a Ranger. But in comparison to the 39mm Explorer, I think the Ranger has a better-looking dial (similar to the Explorer 1016), full length hands and a red seconds hand, lug holes, enough space between springbars and case to fit leather straps properly, 99% brushed steel, and a PVD rehaut, making it more toolish and true to its heritage than the current Explorer. I also like the bracelet with non-fitted end links, such as the ones shown in the pic below of a 1954 Tudor Sub. Finally, and this is just me, I like that Rolex registered the name Ranger in 1929, almost a quarter century before they registered the Explorer name. Oh yes, and it's less than half the price of the Explorer.

Thanks Adam! What's not to like eh? Persuasive arguments.....

Hey everyone,

I recently got a Ranger 79910. I am very pleased, but the reserve doesn't seem to keep up the 38h average.

From a full stop of not working, I did 40 crown windings and left it overnight. I did 12.5h and then stopped. (It was not worn, simply wound 40 times)



How does one test efficiently the power reserve?
Is the mouvement effective?

[faldini]

How do you accurately test the power reserve?

40 windings from a dead stop or wearing it first?

Wound 60 times while already running.

[faldini]

I did another test and it only lasted 12hrs, should the watch be serviced or examined?

Is it a known factor of not being able to reach full power reserve?

[Friar]

Not sure mine was fully wound but still checked out at 41.5 hours. Can't say that I'm unhappy at all!! OTH, as the watch has settled in over a couple of months, it has moved from about +2s/d on the wrist to -1s/d. It is the stiffest watch to hand wind that I have, more than a Hamilton Khaki 2824-2 and much more than a Ball 2836-2.

Adam, I wish you'd stop posting about the Ranger. My resistance has just taken another devastating blow!
