Calibers are the heart of the watch. The “ETHER” in the model name obtains the meaning from the word “etherealness”. The skeletonized tourbillon movement TM2357 of model ETHER-22 is the self-produced movement of TIMING WATCH. By removing all the excess parts of the movement mainplate, the skeletonized pinned tourbillon structure of the caliber is explicitly revealed. No other embellishment or complicated functions, this simple but supremely elegant timepiece charms many watch enthusiasts and horologists.
