I am late...Some Tag Heuer V4 pics

Haha...I met V4 finally! Don't talk too much...letz these pic tell you!

Yup...my hand again...and V4




Getting closer


The case have a very fine finishing... The sapphire crystal was cut to fit the shape of monaco case.


Let get closer on the most amazing part of V4. Mirco-belt are everwhere for transmitting energy between wheels. Tag use Femto laser to shape this mirco-belt with extremely small tolerance!

The sand-polished blued hand is a second hand. It connects to escapement with an intermediate wheel (right) and 3rd wheel (bottom)


This is how this intermediate wheel connecting with escapement wheel




Belts and wheels


V4 is very Photogenic...LOL


Back to technical stuff... A liner winding system with belt. I forgot which directions of the mass falling to, will wind up left / right main barrel modules. But one direction of mass movement will wind up one of the modules. Since the mass have to move backwards and forwards, the degree of winding in 2 modules must be the same when the mass is in middle.

4 barrels in 2 modules, symmetric design. The berrels is not parallel to the case, I feel it just like some pistons on engine!


The energy form barrels transfer to the dial with a coaxial trains on left and right. They are sharing the power with a bigger wheel between these 2 trains. This bigger wheel should be the central wheel as usual watch. And 4 barrels can release their energy at same rate.


But how can 2 non parallet wheel can interact with each other?


Answer is a wheel with special tooth. As you see in the pic, the train coaxial with barrel is tilted. Therefore the train were designed with a bottom-widened tooth, in order to get a largest contact with the intermediate wheel.


This pic tells you how they interact with each other as well! The intermediate wheel is a smaller wheel between tilted wheel and big central wheel.




Thanks for watching! Btw..... Is there any reason a technical innovative photo is photogenic???
