BTF 126500 LN Daytona with DD4131 Movement!

[sfbatman787]

Now this is very interesting!!! I can see what I think is a skeletonized escape wheel in one of the pictures. This is a big deal. The escape wheel starts and stops moving four times per second as it is locked and unlocked by the pallet fork. Each time it stops and restarts it requires energy — energy that comes from the mainspring and doesn’t make it to the balance. This is why Rolex designed the “chronenergy” escapement with a skeletonized escape wheel. By making the escape wheel as light as possible, the amount of energy needed to start it moving when it is unlocked is smaller.

The chronenergy escapement furst appeared on the Rolex 3235 movement, and while Dandong replicated its geometry on the vs3235 movement, they didn’t implement a skeletonized escape wheel. I would be very impressed if they’ve gone the extra mile and done so here for the dd4131.

Excellent observation! Can't wait to see a proper tear down of this movement. I have high hopes!

BT has thicker Subdial rings than Clean:

Also BTF seems to have the bezel numbers closer to the inner edge of the bezel than CF. Should be closer to Gen.

Color of subdial on BT looks more gen than Clean....

I was just quoted 3500 RMB from a non TD

hmm... that's cheap, in fact "too cheap"? I thought non-TD from PRC selling Daytona in the range of 5k RMB?

Nope that's about right for the BTF. Around 3500-4000 yuan for the new gen. 5000 RMB is around the price of the Clean Platona with the Mossainte Markers or the fancy MOP dials.
