Jaeger-LeCoultre

I understand that this watch is very old and was largely ignored during its day, but I'll try to make a case for why it was, and still is, an excellent piece.

In looking for something quite innovative, I had always thought that dual sided Reversos represented the most logical use of the Reverso case. What impressed me the most about the Gran' Sport is its uniqueness amongst Reversos. While the Squadra is proportionally (1:1.6) not a bona fide golden ratio Reverso, the Gran'Sport line is (and is the only other Reverso that bears the same proportion other than the traditional reversos. Another appeal of the watch is its size, at a modest 28.3 mm x 43.5 mm x 12.6 mm, only a hair larger than the Reverso GT I reviewed previously. The movement is an original chronograph movement and as far as i know the only dual sided chronograph.

I can only comment on the overall experience of wearing the watch. Personally, while gold is an admirable material, the Gran'Sport is in all essence a sports watch and is better in the steel version. Although I prefer the steel bracelet for comfort, the rubber strap is a suitable match as well. The back of the case has two curved ridges that elevate the case back off the wrist for comfort. The watch wears similarly to a 38mm watch and wraps very well around the wrist. The integrated bracelet has brushed center links and polished outer links and is wonderfully comfortable with two 4mm adjustments at the clasp (standard on newer JLC sports bracelets).

The bracelet is designed with removable spring bars all along the bracelet, and the case is attached via a notched bar and a screw securing the notch which should prove more reliable than a spring bar.

Accuracy is excellent and within 1 second a day and the seconds hand glides smoothly. Chronograph pushers are not wobbly and the chronograph function works just as promised. After trying the pushers on the Patek 5960P I was surprised about how the JLC's pushers were actually more comfortable and smooth to push. With the possible exception of the price, it's probably the ultimate sports watch. In theory it's possible to go swimming with it but I certainly haven't tried and sometimes I wish the water resistance was a healthier 100m.

Well, Ed, I am very happy that you posted a review on this Gran' Sport Chronograph.  I have long been a huge fan of the calibers 829/859.  Although I would really like to find its older brother, an Anniversary Retrograde Chronograph with the cal. 829, for my own collection someday, the Gran' Sport might serve as a fine alternative and an easier watch to wear, perhaps, on a daily basis. 

I am delighted to hear your comments on its good performance.  That is helpful information.  This is one of the most underappreciated calibers produced by JLC.   It is a good thing that you have refreshed our memories of this Reverso. 

In any case, that is a fine pair of Reversos you have there.

Best,

very comfortable, especially with the curved back in humid weather. The bracelet is quite wonderful too.

It is one of the first models I knew from JLC when I started in this madness of watches in the late nineties.

is even more spectacular than in today's context. I believe retrogrades were very rare and this was also one of the few original chronograph movements to be introduced (in the form of the 829) in some decades.

As you saiid, not very popular during its short life.

Maybe it was sue to its chunky look? Imean the thickness is important for a relatively small watch.

But the movement is great, as well as the dials. I think it will gain in popularity, with time.

After all, in house and manual chrono movements are not legion.

I will save your pos,t in you don't mind.

Thanks; Ed, fdor this well wrtitten article.

Perhaps it will make its comeback, I'm now casually looking for a 829 reverso chronographe which I think also represents a great value.

Thank you Ed, 

A question I always had... And which I could never solve. Do you prefer it with the black dial, or with the white dial?

I find both have a lot of charm, to say all. And that some developped a superb patina, too, due to  tritium on some early dials.

Best,

Nicolas

I have the gran sport duo on a rubber strap, and i will add that it proved more comfortable than my patek 5066 on a strap simply due to the adjustable trap size (and hoe easily done on the fly), as well as the built in curvature to the strap at the ends of he wrist for superior wrap around.  Though, i will concede that the chronograph on a bracelet is the one that got away for now.  One day i will trade one for the other.  It is the sole watch that has never given me any triuble, and i truly abuse it at work, home, play, vacations...  5atm waterproof yes, but i never had any issues with high power shower heads, heavy operating room faucets, or diving in greece.  I hope his makes you feel better abiut th 5 atm rating and o for one in case you dont own one.  Additionally, it is my first high quality swiss watch, so i will always feel encanted by its utilitarian nature and rugged design.  Not to mention as a teenager, the first time i saw an add for a reverso andwondered hat the hell it was.  Now i still believe that a reerso is purely for a functional rear or an openback, since no one plays polo with them any more, and there is no more functional revero than the gorgeous gran sport chrono (with the grey dial of couse).  Enjoy yours.

Though, I would advice you to not dive with it... Don't try your luck too often, it may tuirn.

It is good to read such a testimony, and to see that they are so strongly linked to our lives, rather than staying in a safe, at a bank.

You are a lucky guy, Dimitri, the Reverso Gran Sport Duo is a cool watch, yes, very cool.

Best!

Nicolas
