Horological Meandering

TAG Heuer continues in its quest to rethink out of the box with another 'under the nose reinvention', after substituting the traditional pinion and gear transmission with a belt-driven mechanical transmission (which many thought it could not be achieved w...  

i don't like the size. 48mm diameter is huge and if it goes into production it would put me off buying such a piece. It is possible the finished product will have a smaller case at all? thanks darren

Hi Darren Hopefully it was not my small wrist that blow the watch out of proportion. Must get a more macho wrist next round Likewise I felt it would be nicer if it can be kept at 44mm, however, the movement diameter is already at 40mm. Kong

Would love to see this "thing" working properly, and being reliable soon. Vte This message has been edited by VMM on 2010-05-31 01:38:00

many will have more faith with TAG Heuer after they started delivery of V4 last November, which many doubted would happen. We shall see, what the material scientists/engineers could do in next few years. Kong

report, thank you for such detailed photographs! I like the watch very much but I also think it's too large, it might be a necessity for this movement though.

Hi Amvox Thanks for viewing. It would be challenging to reduce from current 47mm as the movement itself is at 40mm. Kong

Interestingly, the new concept of pendulum works like tourbilion and more meaningful. I hope TH will manufacture this watch with smaller diameter (not more than 42mm) and longer power reserve (at least 40 hours and above). Any constraint faced by TH? Than... 

at the moment, mentioned is the magnets still sensitive to temperature and at the moment may not keep tight rate. Reducing to 42mm, may not be possible as the movement is already at 40mm. Kong

but looks utterly ridiculous at that size. No offense.

The size is crazy and the name 'Graaaaaand' Carrera is a dealkiller. Just my O. I guess a watch brand best known for sport and entry level nice watches should not use a word like Graaaaand, as if an English aristocrat is the target? It always irked me and... 

appropriate naming is important! Kong

Reminds me a bit of the inventiveness and imagination behind the Spring Drive from Seiko and, of course, the co-axial technology escapement from Dr. George Daniels. I think Audemars Piguet has a revolutionary movement also, right? The hairspring and escap... 

I would say. Yes indeed it reminded about the Spring Drive with the tri-synchro regulator but without the electronics which require battery to power. Most companies can conceptualize, develop and manufacture their movements. However, few can manufacture t... 

If i have to demagnetized it.... will the virtual hair spring lost its magnetism? btw great report! thx

magnet will be detrimental to this alternative regulator. Any upset of balance of the magnetic field in any of the four magnets, doubt the balance wheel will oscillate properly. I like your pictures, they are nice! Kong

I think the situation is same as spring drive as well...and i asked the agent from seiko HK before about the effect on magnetism of spring drive. They gave me an uncertain answer, but i still believe it works unless you bring them into a lab or near some ... 

Hi Ogygia Based on my understanding (till someone willing to loan one to test ) , even Spring Drive, it should be affected when near to any strong magnet as the electromagnetic field of the 'braking & release' would be interrupted, affecting the constant ... 

lol....I think no watch owner willing try, but a scientist...as you said... I love the seiko spring drive...especially the smooth motion of the second hand. It really tells the flow of time. I believe I will love this TAG when i meet it...since they are s... 

even in TAG Heuer's press materials. It is an 'alternative' without any electronics (like an integrated circuit, IC) so it is different from Spring Drive. Kong PS : Thanks Elvis for the kind words. Actually each time, I go to a new venue, I hope there is ... 

This is a piece i have been keeping tabs on.Awesome and i have to agree with most here..kinda big.Cheers

challenge, as most of us felt the same. Thanks for viewing. Kong

What does it sound like? A

escapement as the escape-wheel and pallets are still being used. The environment was not quiet enough for me to record. Kong

Very nice project!!! But i realy don't know how they adjust/keep the frequency? Isochronism problems? Some one might explain me?
